Music and the Brain: Processing and Responding (A General Overview)
For any individual who either avidly listens to or performs music, it is understood that many melodies have amazing effects on both our emotions and our perception. To address the effects of music on the brain, it seems most logical to initially map the auditory and neural pathways of sound. In the case of humans, the mechanism responsible for receiving and transmitting sound to the brain are the ears. Briefly stated, the outer ear (or pinna) 'catches' and amplifies sound by funneling it into the ear canal. Interestingly, the outer ear serves only to boost high frequency sound components (1). The resonance provided by the outer ear also serves in amplifying a higher range of frequencies corresponding to the top octave of the piano key board. The air pressure wave travels through the ear canal to ultimately reach and vibrate the timpanic membrane (i.e.-- the eardrum). At this particular juncture, the pressure wave energy of sound is translated into mechanical energy via the middle ear. Here, three small bones, the ossicles, vibrate in succession to produce a unique pattern of movements that embodies the frequencies contained in every sound we are capable of hearing. The middle ear is also an important component in what music we actually keep out of our 'head'. The muscles grasping the ossicles can contract to prevent as much as two thirds of the sound from entering the inner ear. (1, 2)
The mechanical motions of the ossicles directly vibrate a small membrane that connects to the fluid filled inner ear. From this point, vibration of the connective membrane (oval window) transforms mechanical motion into a pressure wave in fluid. This pressure wave enters and hence passes vibrations into the fluid filled structure called the cochlea. The cochlea contains two membranes and between these two membranes, are specialized neurons or receptors called Hair cells. Once vibrations enter the cochlea, they cause the lower membrane (basilar membrane) to move in respect to the upper membrane (i.e. --the tectorial membrane in which the hair cells are embedded). This movement bends the hair cells to cause receptor potentials in these cells which in turn cause the release of transmitter onto the neurons of the auditory nerve. In this case, the hair cell receptors are very pressure sensitive. The greater the force of the vibrations on the membrane, the more the hair cells bend and hence the greater the receptor potential generated by these hair cells.
Hearing allows us to take in noises from the surrounding environment and gives us a sense of where things are in relation to us. All those little folds on the outside of the ear, called the tonotopic organization, make it so sound waves in the air are directed to the ear canal, where they can be further processed. Once in the ear, the sound waves vibrate the ear drum, which tell the ear exactly what frequency it is sensing. The vibration of the ear drum is not quite enough to send a signal to the brain, so it needs to be amplified, which is where the three tiny bones in the ear come into play. The malleus or hammer, incus or anvil, and stapes or stirrup amplify this sound and send it to the cochlea. The cochlea conducts the sound signal through a fluid with a higher inertia than air, so this is why the signal from the ear drum needs to be amplified. It is much harder to move the fluid than it is to move the air. The cochlea basically takes these physical vibrations and turns them into electrical impulses that can be sent to the brain. This is...
Nuclear power is a relatively new method of supplying the ever growing population with the electricity that is required. Although the majority of people are unsure of how generation occurs, nuclear power provides roughly 17% of the world’s power. (Rich, Alex K...) This makes nuclear power a deciding factor in how the race progresses in technology and energy fabrication as it is able to produce mass amounts of electricity in short periods of time. The limit potential for nuclear power is unclear in not only energy but also weaponry and some medical uses. The fact that uranium and the radioactivity that comes with it are used in facilities and other inventions often lead people to distrust the inventions which, while not entirely un-called for, hinders progress and leads to fables and tales around nuclear energy, its creation, and the nuclear power plants that are springing up around the world. This causes nuclear facilities to slow in their development which only makes things worse because as things progress the facilities will only get increasingly safe as long as they are handled professionally. (Rich, Alex K…) Some of the slanderous fables around nuclear power include things like claiming that nuclear facilities cannot operate during droughts and water shortages. (Kharecha, Pushker…) While nuclear power is accompanied by several risks, it can also be the solution for various global strains and difficulties.
Music is defined as vocal or instrumental sounds combined in such a way as to produce beauty of form, harmony, and expression of emotion, but music is not bound by its meaning. Music can be almost anything a person wants it to be. No one can put a date on the beginning of music. Some say it began before humans spread around the world or possibly originated in Africa. A conclusion that most people would agree on is that music has been around for mostly all of time. Whether or not people know it, music is a key aspect of their lives, and it affects them in many ways. One may begin to question why do humans participate in and enjoy music so much? This question can never have a concrete answer, but many have ideas of what might be the reason.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
But as long as the note is in the right context, it sounds fine. As humans, we have grown to develop a sort of musical grammar in detecting a wrong note. We develop an awareness to the knowledge of the rules of how certain sequences are made, very much like grammar with linguistics. Now, musical grammar can be a lot more complex than just a sour note, and can greatly differ depending on the culture you were raised in. And just as with language, this grammar has to be learned. The evidence being that infants don’t seem to be sensitive to this (21).
A transducer is a mechanism that changes one form of energy to another form. A toaster is a transducer that turns electricity into heat; a loudspeaker is a transducer that changes electricity into sound. Likewise, an ultrasound transducer changes electricity voltage into ultrasound waves, and vice versa. This is possible because of the principle of piezoelectricity, which states that some materials (ceramics, quartz, and others) produce a voltage when deformed by an applied pressure. Conversely, piezoelectricity also results in production of a pressure whe...
The brain is a very powerful organ, no doubt. It tells your body how to react and what to do. But what happens when you listen to music? How does your brain react? Let’s take a look.
The need for nuclear energy is more widespread today than it has been for decades. Drastic climate change and the rising prices of fossil fuels such as oil have made many scientists seek an alternative energy source. Although nuclear energy has been around for decades, the use of it has always been approached by pessimism. Because, the misuse of nuclear energy could spell disaster for any country involved in the process. Events like Three Mile Island, Chernobyl, and Japan’s Fukushima accident are reminders of how nuclear energy can go wrong. However, the continued use of fossils fuels can spell disaster for the international and domestic security of any country that is dependent on the energy source. Fossil fuel is a limited resource, meaning that the continued use of this energy source can run out one day and this could mean disaster to any country dependent on fossil fuels. Therefore, the continued use of such an energy source could spell disaster for a country's domestic and international security in the future. An alternative energy source is needed in order to control the world's consumption of fossil fuels, nuclear energy is that energy source. Although nuclear energy has been establish as a feasible energy source, it has not yet caught on due to certain nuclear events. Events like Chernobyl and Three Mile Island reinforce the belief of nuclear energy as a dangerous risk. But, we can see France as a perfect example of using nuclear energy without any nuclear disasters. Nuclear energy can be the energy source we need to be free from fossil fuels, and benefits outweigh the cons of nuclear energy.
Music is one of the few things that has remained constant through the centuries this world has existed. Not only does music provide entertainment, it also has several effects linked to it. Music allows emotions of happiness and sadness to arise. From those emotions, physical effects, negative or positive, can occur. Music has a profound effect on the emotional, social, intellectual, and physical aspects of a person.
When we listen to music a number of things occur: we process sound through the auditory complex, an artist’s movement through the visual cortex, dancing and other rhythmical movement through the cerebellum. The Motor Cortex also enables movement such as foot tapping or hand clapping. Our Hippocampus stores our experiences through music and enables musicians to remember musical pieces. Finally, the Amygdala allows for emotional reactions to music. Because music is a combination of our different senses, we as individuals can process things differently and naturally we will like some genres more than others. Music is one of th...
Bullying has been a part of schooling for as long as children have been congregating. To some it seems like a natural, though uncomfortable, part of life and school experience, while to others it can mean terrifying experiences which spoiled and characterized otherwise happy years in school. Dan Olweus, a pioneer in bully behavior research documented that 2.7 million children are affected as victims, and that 2.1 children act as bullies (Fried, 1997, as cited in Aluedse, 2006). With bullying cited as the reason for violent, gun-related crime in the past few years, school districts as well as national governments have put anti-bullying policies in place. Bullying is a complicated phenomenon, involving more than one child demanding lunch money from a smaller child. It is a worldwide epidemic hitting schools everywhere. Virtually everyone has seen or experienced bullying. With technological advances, bullying is even hitting the internet. Parents, teachers, students and governments agencies alike are attempting to put a stop to bullying practices.
The ear is looked upon as a miniature receiver, amplifier and signal-processing system. The structure of the outer ear catching sound waves as they move into the external auditory canal. The sound waves then hit the eardrum and the pressure of the air causes the drum to vibrate back and forth. When the eardrum vibrates its neighbour the malleus then vibrates too. The vibrations are then transmitted from the malleus to the incus and then to the stapes. Together the three bones increase the pressure which in turn pushes the membrane of the oval window in and out. This movement sets up fluid pressure waves in the perilymph of the cochlea. The bulging of the oval window then pushes on the perilymph of the scala vestibuli. From here the pressure waves are transmitted from the scala vestibuli to the scala tympani and then eventually finds its way to the round window. This causes the round window to bulge outward into the middle ear. The scala vestibuli and scala tympani walls are now deformed with the pressure waves and the vestibular membrane is also pushed back and forth creating pressure waves in the endolymph inside the cochlear duct. These waves then causes the membrane to vibrate, which in turn cause the hairs cells of the spiral organ to move against the tectorial membrane. The bending of the stereo cilia produces receptor potentials that in the end lead to the generation of nerve impulses.
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
Music has incredible effects on the brain and body! Ever since the beginning of time, music has been around. It can influence the way a person thinks and behaves, and also social interactions. Teens are more susceptible to this (Revatto 1). Music can be used in therapy by helping people with depression, and can even be a more natural way to heal the body (“How Music...” 1). In some cases, songs and melodies can help or make diseases worse. Music is a powerful thing and can affect your brain and many other things in your body in numerous ways.
Bullying has always been present within the United States. Although the issue has been around for a long time, it continues to grow and become more of problem. It is said that about 160,000 children within the United States are refusing to go to school because of bullying. Another statistic is that within American schools alone, there are an estimated 2.1 billion bullies and 2.7 billion victims (Dan Olewus, MBNBD). The numbers presented here are outrageous and although there are organizations to stop bullying, obviously there needs to be a new set of solutions. Any type of bullying presents problems to children, “Suicide, depression, anxiety, substance abuse, trouble with the law, poor performance in school and work, and lack of involvement in socially accepted activities are some of the difficulties resulting from bullying (Austin, Reynolds, Barnes, Shirley). Of course, there is more than just a single type of bullying. Feeding ground for bullies can range anywhere from text-message or cyberbullying to physical bullying in schools. Also, bullies can begin to strike at a young age and could also be; teenage, middle-age, or even the elderly. Even though there are these many versions of problematic bullies, the largest bullying problems take place within the school setting: a place that is supposed to be safe for children rather than harmful. Although it seems impossible to completely get rid of bullying, these are a few suggested solutions; making the school informed on bullying issues, schools implementing rules on bullying, and having students positively use electronics to stop bullying.
