associated with a lesions on the posterior inferior frontal gyrus of the brain, has cardinal features that distinguish is from other fluent and non-fluent aphasias (e.g. poor repetition, poor repetition and poor naming with good auditory comprehension). Within this model, the general assessment process of an aphasic person consists of: (1) Gathering the client’s case history (e.g. a car accident that results in an injury to the anterior superior frontal lobe (in the case of Transcortical motor aphasia));
Diversity across cultures differs remarkably when it comes to social norms, but among all these different cultures lies one similarity: psychopaths. A psychopath is defined as a person suffering from a mental illness who portrays abnormal or violent behavior, has deficient emotional processing, and an absence of morals pertaining to appropriate decision making. Despite the growing research in the field of psychopathology and neurobiology, the neural substrates underlying these bizarre and fierce
are also involved in the processing of spoken language. A difference between the processing of sign language and spoken language is that sign language activates the superior and inferior parietal lobules. The superior parietal lobule is thought to be important for proprioceptive monitoring during signing and that the inferior parietal lobule is needed for phonological processing and is employed during the production and imitation of hand movements. Sign language and spoken language have both similarities
Heatherton, Wyland, & Kelley, 2006). Furthermore, during the negative stereotype situation the left inferior temporal gyrus got activated, which processes advanced tasks (Kanwisher et al., 1997 in Wraga, 2006), as well as the right inferior and left superior parietal lobule spatial processing area (Wraga, 2006). The last two regions of activation in stereotype threat were the left fusiform gyrus and cerebellum (Wraga, 2006). The activation of the cerebellum, as well as the caudate and thalamus are
language processing was developed by Broca (1861) and Wernicke (1874), later extended by Lichtheim (1885). It implicated two brain regions involved in language production and comprehension - Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s area in the posterior superior temporal gyrus (pSTG), respectively. It suggested that Broca’s area stores motor representations of words while Wernicke’s area contains the information about what the words sound like as well as what their meanings are.
presented at the start of the trial increased. Moreover, it was established that the average visual short term memory capacity was capped at three to four objects. fMRI data was collected and analyzed from three brain regions: the intraparietal sulcus/inferior occipital sulcus (IPS/IOS), the ventral-occipital cortex (VO) and the anterior cingulate cortex (AC). Activity in the IPS/IOS seemed to increase as the load of the task increased and it was shown that this region was active during maintenance and
for spoken language, known as the Brodmann area 44 and 45, is situated in the left inferior frontal gyrus (Goodglass and Kaplan (2001). Damage affecting this Broca’s area may cause a ‘non fluent’ aphasia, in which comprehension remains relatively intact, however language production is impaired (McCaffrey, 2005). The most well known cause of Broca’s aphasia is a Middle Cerebral Artery (MCA) stroke in the left frontal lobe. John is cognitively aware of what he wants to say, however he is unable find
Evil is a metaphysical term used to describe the thoughts and actions of humans that are seen as morally wrong or ‘bad’. In extreme cases even a person can be labelled as overall evil, such as Adolf Hitler and Jeffrey Dahmer. Previously, it has been thought that a person has the ability to choose between being ‘good’ or ‘evil’ and that they simply make this decision based upon what pleases them. Recently, however, neuroscientists have shed some light upon the physical explanations of human thought
A psychopath is someone who is unable to live harmoniously in society due to their profound lack of compassion, empathy, conscience, and remorse (Hare, 1993). Many psychopathic symptoms have been proposed to result from cognitive and emotional processing impairments. The concept of a psychopath is often of a ruthless and dangerous criminal, an image commonly depicted in the media and film. Though psychopaths do make up an estimated 40% of dangerous offenders in Canada, it is the non-violent manipulators
In this article called, "The New Science Behind Your Spending Addition", by Sharon Begley and Jean Chatzky, they explain about the vice versa of immediate gratification versus delayed gratification and why more people tend to attract to immediate gratification. Begley and Chatzky expound on how humans choose to spend rather than save. Some people may call it "The American Quirk". Begley and Chatzky apply a short story about a father name, Leonard Green who is a professor of psychology at Washington
loss of ability to understand speech because of brain damage. Broca’s Aphasia can happen when an individual has a stroke and damages the frontal regions of the left-hemisphere. Aphasic disorders are categorized as fluent or nonfluent aphasia. Broca’s Aphasia is classified as nonfluent because of a lesion in the left frontal lobe on the left posterior inferior frontal region, called Broca’s area. This subdivision of the brain is important for the ability to form sentences and to string words together
is associated with the size of a brain. In 2001, scientists from Harvard University found that certain parts of the brain were differently sized in males and females, this may balance the overall size difference. The study found that parts of the frontal lobe (responsible for problem solving and decision making) and the limbic cortex (responsible for regulating emotions) were larger in females. In males, the... ... middle of paper ... ...O. (2013, december 3). the atlantic. Retrieved may 11, 2014
Introduction Psychopathy is a personality disorder whose core diagnostic features include increased fearlessness, shallow affect, callousness, and poor behavioral inhibition. The actions of psychopaths often come at a large cost to society and its citizens, and their empathetic deficit is one of the reasons psychopaths can be so efficiently destructive in many people’s lives. The importance of understanding this deficit cannot be over-asserted. If psychopathic empathetic deficit can be understood
Perceptual Agnosias Introduction Agnosia is a clinical condition characterized by disordered perception situated at an intermediate stage between primary sensory defect and general intellectual dysfunction (Hécaen & Albert, 1978; Mather, 2009). Agnosias are described as the loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not impaired nor is there any significant memory loss (Mather, 2009) A person can have a deficit in the visual, auditory, olfactory

Also, each nerve has a specific name such as, olfactory, optic,etc, which is
is recalled from short-term or long-term memory (Mastin, 2010). Information excerpted from sensory input into the memory system changed into a form that the system can cope with and then stored it. The scientist believes that the hippocampus with frontal cortex is responsible for analyzing various sensory inputs before deciding to store information in long-term memory (Martin, 2007). These various bits of information are then stored in different parts of the brain, then identified and retrieved to
Damage to the frontal lobe cortex of the brain can cause difficulty in everyday activities. The frontal lobes role in people’s behavior includes executive processes, language, emotional expression and movement. Ryan Godfrey has difficulties in some areas of executive processes due to the damage tumors caused in his brain. Ryan and others with frontal lobe damage can benefit from knowing these deficits by taking steps to reduce their impact. The brain tends to compensate for damaged parts and a faith
seen by performing tasks and examining brain activity before and after automaticity training.

As he may be creative to motivate students, he has to generate creativity in his pupils. In this way, understanding the relation between the neurobiology of creativity and its cognition is useful to every teacher. Introduction Creativity is a complex process to be studied, however a lot of recent researchers in Neuroscience and Education have worked in this topic and have established
Teal Jenkins NEUR/ZOO 5100 Dr. Prather Spring 2014 Broca’s Aphasia • Background Aphasia is defined as the inability to communicate and is caused by damage to areas of the brain responsible for language processing [1]. Strokes are the main cause of aphasia, while tumors, blows to the head, and infections can also be the culprits. Aphasia affects the ability to comprehend and produce language, whether written or verbal. Approximately 80,000 people acquire aphasia each year, with men and women being
