Mysteries of the extrastriate body area

Visual perception of human body is a critical component of this complex task as long as it provides cues which enable the observer to make the required inferences to accurately extract the meaning of daily action events. During the last decade, neuroimaging studies have identified two brain regions of the extrastriate visual cortex that are highly sensitive to the perception of human bodies and body parts.

You can always count on the journal Medical Hypotheses published by Elsevier for a good laugh. The Editor-in-Chief Bruce G. Charlton accepts all sorts of completely speculative crackpot articles. Who can forget the classic, Is there an association between the use of heeled footwear and schizophrenia?

The behavioural cluster associated with depression includes adoption of a hunched posture, avoidance of eye contact, loss of appetite for food and sex and sleep disruption. When viewed in this context, it becomes clear that many of the brain areas that mediate these behaviours e.

In consequence, it is proposed that depression has its origins within this ventricle. Therefore, it is hypothesised that the behavioural expression of this adaptation is mediated by a single or pulsatile release of a yet to be identified noxious factor into the ventricular space.

Where did these ideas come from??

How hearing 'twist my arm' engages the brain

Like most everyone else, Hendrie and Pickles are not satisfied with the current crop of antidepressants or with the monoamine hypothesis of depression Hirschfeld,which is incomplete at best.

Then they take a giant leap and make up one of those evo psych just-so stories: This analysis accounts for why it is life events such as the death of a spouse or a child that are major causes of depression.

How about the death of a sister or a grandmother or an uncle? Or a beloved pet? Do these tragic events damage the reproductive potential of those who are prone to depression in such circumstances?

And why is the third ventricle so important? Hence, it is proposed that this may well be the site where the behavioural expressions of depression are initiated. Functions of structures closely associated with the third ventricle. The table shows those structures that directly border the third ventricle and those that are connected to it via structures that pass through.

The function of the behavioural cluster associated with depression is to reduce the emission of attack provoking stimuli.

This is achieved through increased defensiveness, decreased motivation to engage in consummatory behaviours and sleep disturbance, so that there are activity peaks at times when other individuals are inactive.

The damage produced by the release of a noxious substance into the CSF [cerebrospinal fluid] is not under precise control And how are we supposed to identify this unknown toxin released into the CSF in order to develop new treatments?

They come up with two ideas:Nov 01,  · These regions are the extrastriate body area (EBA), located at the posterior inferior temporal sulcus/middle temporal gyrus (Downing et al., ) and the fusiform body area (FBA) found ventrally in the fusiform gyrus (Peelen and Downing, ; Schwarzlose et al., ).
