| Research Abstract |
Perception and recognition of human face are critical cognitive function in humans. Aim of the present study is to investigate brain mechanisms of face perception and recognition using normal human subjects and functional magnetic resonance imaging. We conducted brain activation studies involving processing of negative expressions, false memory of faces, and emotional empathy for happy and sad expressions. We also translated English version of "Hereditary Prosopagnosia Questionnaire" to Japanese. The results indicate that transient activity in the amygdala is critical when the subjects recognize negative emotion. False memory of faces involved neural activity in the amygdala and medial prefrontal cortex. Emotional empathy for happy and sad expressions is subserved by activation in distinct and common brain regions. We provided data of prosopagnosia questionnaire obtained from a large sample of Japanese university students.
