The concept that makes sense the most is the basic cells of the nervous system. The concept of the neuron forms the basis of understanding cells and the nervous system. I recognize the importance of neurons (nerve cells), where the chemical excitation process created by the dendrites. Neuron communication also depends on resting potentials, where it is necessary that there are chemical contrasts that are necessary to create equilibrium. Additionally, in communication, the neurons require energy redistribution, and the neurons are useful when connections are made. The structure of neuron explains how the communication process takes place where the neurons grow appendage is the form of dendrites. Information is sent to a neuron through the axon formation and even as neurons have various dendrites they have one axon. It is the axons that carry information to other neurons, and dendrites receive input from various neurons.

Neuroscientists have made discoveries on the way the brain operates, but the neurons are complex, even when integrated into a network. Even though, there was the representation of how the synapses enhance neuron communication, the relation of synapses to other aspects of neuronal communication is not very clear to me, there are tiny gaps that allow two neurons to meet and mostly share one synapse. However, there is the possibility that the two neurons share multiple synapses, and this was not explored. It seems that the message transited from a neuron to another depends on the synapses, where even changes in the synapses influence how the message is transmitted. The reasons for the transmission of signals being either electrical or chemical and how this influences how two neurons communicate needs to be elaborated
A synapse is the space between a presynaptic neuron and postsynaptic neuron. This is the location where chemical and electrical messages are transmitted from one neuron to another. Synapses are essential to neuronal function. They serve as a means of communication between neurons.
During her presentation, Bonnie Bassler expends many different aspects of communication in a bacterial level and how successful communication is important to survival and efficient functioning. It is evident from her presentation that without a common language to communicate with, bacteria could not work as efficiently as they do, neither to immunize people nor create havoc in them. In her presentation, Bassler asserts the importance of the use of language in communication in bacteria, using rhetorical appeals – logical, ethical and emotional – and how it is consequently related to humans.
Neurons dispatch signals to other cells through thin fibers called axons, that cause chemicals acknowledged as neurotransmitters to be released at junctions identified as synapses. A synapse gives a command to the cell and the entire communication process typically takes only a fraction of a millisecond.
"Neurones monitor or control specific cells or groups of cells" (Martini et al. 2014). The nervous response is rapid, however precise and short-lived, due to the fact that neurotransmitters are broken down and recycled very quickly after they have diffused across the synaptic cleft - in contrast, not all life processes are short-lived, and many require a longer response time. For example; the body continually maintains reproductive capabilities for many years, and other life processes such as growth and development require responses with a long-life span. In addition, not all of the cells in the body are innervated, which means that some cells in the body cannot be reached by the nervous system. As such it is evident that hormones have a major role to play in cellular communication, and the nervous system on its own would not suffice. (Martini et al.
The brain is part of the central nervous system, which consists of neurons and glia. Neurons which are the excitable nerve cells of the nervous system that conduct electrical impulses, or signals, that serve as communication between the brain, sensory receptors, muscles, and spinal cord. In order to achieve rapid communication over a long distance, neurons have developed a special ability for sending electrical signals, called action potentials, along axons. The way in which the cell body of a neuron communicates with its own terminals via the axon is called conduction. In order for conduction to occur, an action potential which is an electrical signal that occurs in a neuron due to ions moving across the neuronal membrane which results in depolarization of a neuron, is to be generated near the cell body area of the axon. Wh...
Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system.
I did find it interesting how the individual neurons receive messages as to how a computer does. “An individual neuron may receive information from thousands of other neurons.” From my basic study of how a computer functions this is not the case in them. Computers receive information from various sources but nowhere near thousands, and when the message is relayed it is immediately carried out. However in neurons this is not the case as stated by Chudler. “Remember, the receiving neuron may be getting thousands of small signals at many synapses. Only when the total signal from all of these synapses exceeds a certain level will a large signal (an action “potential”) be generated and the message continued.” This is much different from a computer, for every keystroke and action is immediately taken, where as in our brain it takes thousands of synapses milliseconds to make me type. The speed and accuracy of my typing is affected by the ability of my neurons to send action potentials.
The number of synaptic inputs recieved by each nerve cell in our (human) nervous system varies from 1-100,000! This wide range reflects the fundamental purpose of nerve cells, to integrate info from other neurons.
The neuron plays an important role in the occupation of the brain (Rollin Koscis). A neuron is...
As the human body goes through different experiences, the brain grows, develops, and changes according to the environmental situations it has been exposed to. Some of these factors include drugs, stress, hormones, diets, and sensory stimuli. [1] Neuroplasticity can be defined as the ability of the nervous system to respond to natural and abnormal stimuli experienced by the human body. The nervous system then reorganizes the brain’s structure and changes some of its function to theoretically repair itself by forming new neurons. [2] Neuroplasticity can occur during and in response to many different situations that occur throughout life. Some examples of these situations are learning, diseases, and going through therapy after an injury.
Synaptic transmission is the process of the communication of neurons. Communication between neurons and communication between neuron and muscle occurs at specialized junction called synapses. The most common type of synapse is the chemical synapse. Synaptic transmission begins when the nerve impulse or action potential reaches the presynaptic axon terminal. The action potential causes depolarization of the presynaptic membrane and it will initiates the sequence of events leading to release the neurotransmitter and then, the neurotransmitter attach to the receptor at the postsynaptic membrane and it will lead to the activate of the postsynaptic membrane and continue to send the impulse to other neuron or sending the signal to the muscle for contraction (Breedlove, Watson, & Rosenzweig, 2012; Barnes, 2013). Synaptic vesicles exist in different type, either tethered to the cytoskeleton in a reserve pool, or free in the cytoplasm (Purves, et al., 2001). Some of the free vesicles make their way to the plasma membrane and dock, as a series of priming reactions prepares the vesicular ...
The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place.

Neuro Linguistic Programming (NLP) was developed in the 1970s by a linguist John Grinder and by a mathematician Richard Bandler. Neuro Linguistic Programming (NLP) is a therapy that deals with one’s perceptions of the world by their experiences, beliefs, values, assumptions, and sensory systems. NLP was developed by studying and examining the modeling pattern of human internal and external behaviors of the world. According to NLP website, “NLP investigates the inner functions of the human mind: how we think, how we develop our desires, goals and fears and how we motivate ourselves, make connections, and give meaning to our experiences” (NLP Comprehensive, 2013). NLP entails various collections of psychological practices that target to improve peoples’ lives. Mainly, it is a therapy of motivating the conscious mind by acting upon the unconscious mind; the experience is subjective to the person.
The most basic elements of a neural network, the artificial neurons, are modeled after the neurons of the brain. The "real" neuron is composed of four parts: the dendrites, soma, axon, and the synapse. The dendrites receive input from other neuron's synapses, the soma processes the information received, the axon carries the action potential which fires the neuron when a threshold is breached, and the synapse is where the neuron sends its output, which are in the form of neurotransmitters, to the dendrites of other neurons. Each neuron in the human brain can connect with up to 200,000 other neurons. The power and processing of the human brain comes from multitude of these basic components and the many thousands of connections between them.
