We conducted a slow event-related fMRI experiment with naïve subjects’ passively viewing yawn and various other control videos along with correlative behavioral testing. Specifically associated with the viewing of the contagious yawn was an area of activation in the ventromedial prefrontal cortex ...

The relationship among self, mind and brain is not clearly known. Self’s subjective experiences of perception and cognition of words, feelings, thoughts etc. is supported by the integrity of human brain. The relationship between the self and the human brain activity is not understood. Recent experimental evidence suggests that the neural correlate of consciousness is located in certain parts ...

5/28/2012 · The Kana Pick-out Test (KPT), which uses Kana or Japanese symbols that represent syllables, requires parallel processing of discrete (pick-out) and continuous (reading) dual tasks. As a dual task, the KPT is thought to test working memory and executive function, particularly in the prefrontal cortex (PFC), and is widely used in Japan as a clinical screen for dementia.
