Dentate gyrus

hypothalamic pituitary adrenal (HPA) axis (Kolb and Whishaw, 2013). Aged individuals tend to exhibit elevated levels of corticosteroids, which promote hippocampal deterioration (Cameron and McKay, 1999). A specific region within the hippocampus, the dentate gyrus, is unique in that it not only succumbs to such effects but continues to undergo neurogenesis (Cameron and McKay, 1999). However, the rate of neurogenesis is reduced if not inhibited in old

reseach in cognitive neuroscience” (p. 287). Sensory basis for prosopagnosia are important to be looked at, because it tells you what areas of the brain are associated. Prosopagnosia occurs due to the damage to the fusiform face area, in the fusiform gyrus that is located in the temporal lobe and damages to the to the occipital face area located in the occipital lobe (Grüter, Grüter, & Carbon, 2008, p. 82). However in individuals who experiences developmental prosopagnosia seem to have normal fusiform

Agnosia is defined as the inability to recognize objects through the processing of sensory information, which means there is no deficit in semantic memory or problems with naming objects. An individual suffering from agnosia still possesses all the relevant semantic information tied to a precept, but they cannot recognize the precept when it is presented to them and therefore trigger the recall of said information. There are many types of agnosia, but this essay will focus on visual object agnosia

Are faces special? Critically evaluate the evidence that we have evolved a specialised neural network dedicated to processing faces. Brian Marron, 11461992, SF TSM. INTRODUCTION Processing faces is extremely important to humans as social beings. We are able to put and identity on thousands of faces (Gazzaniga, 2002) with ease, something we might take for granted. The value of this ability can be better understood when the world is viewed through the eyes of somebody with prosopagnosia, the inability

Recognizing a face is a starting point when interacting socially, as it is the most important stimuli we see. The face portrays information about a person’s identity, their emotional state and where they are directing their visual attention. To be able to process this information within a very short space of time is crucial in social interactions and probably dates back to our ancestor’s survival. The human brain is very adept in processing an abundance of information in a simple yet effortless

The face recognition model developed by Bruce and Young has eight key parts and it suggests how we process familiar and unfamiliar faces, including facial expressions. The diagram below shows how these parts are interconnected. Structural encoding is where facial features and expressions are encoded. This information is translated at the same time, down two different pathways, to various units. One being expression analysis, where the emotional state of the person is shown by facial features. By

specifically, aiming to find the precise area that this face recognition is processed in. Is there a specific area of the brain that is responsible for recognizing faces? More specifically, is the fusiform gyrus the area

correct response rates for recognizing affect via emotional words and facial emoticons. They also found that the part of the brain, called the fusiform gyrus, in the participants with ASD had a greater activation rate during emotional word tasks when compared to their typically developing peers. Interestingly, the investigators found that the fusiform gyrus of the participants with ASD had less of an activation response to facial emoticons when compared to their typically developing peers (Han et al.,

Prosopagnosia, or face blindness, is a neurological disorder that prohibits an individual’s ability to recognize faces. It can occur in several different manners, each with different levels of severity. Some who have it are simply unable to recognize faces of familiar individuals, while those with more severe forms cannot distinguish between objects and faces, or even their own reflection. In some of these cases, it can be accompanied by issues with recognizing other objects such as cars or places

In today’s modern world, more and more schools are incorporating electronics in the curriculum, but these changes are having immeasurable effects on students including the demise of their handwriting. The art of handwriting has been around since its invention in 4000 BC, and according to Anne Chemin, Mesopotamia was more than likely the birthplace of handwriting (Chemin). In recent years, however, handwriting has become more of a chore than a learning utensil to students. But at what cost? Handwriting
