Our findings suggest that the patients who responded poorly to antidepressants were morphologically and cognitively impaired, whereas the treatment responsive patients showed less structural changes and relatively preserved cognitive functions. Keywords: Antidepressant responsiveness; Cognitive There is a local representation of the retinal receptors. Between-group analysis of DKI parameters. 3) Begin masking -motor homunculus. Finally, weaker cortisol reactivity in BD cases exposed to high levels of trauma was associated with increased activation in the lingual gyrus only, representing potential disorder-specific impact of changes of the stress system on emotional brain function, following childhood trauma exposure. Further, impaired visual memory is related to either damage to the region or disconnections between the gyrus and other brain structures. Visual memory dysfunction and visuo-limbic disconnection have been shown in cases where the lingual gyrus has been damaged (due to stroke or other traumatic brain injuries).
