| Outline of Final Research Achievements |
Insufficient/improper behaviors toward goal-direction appear when something else occupies one’s mind. This study aimed to solve such failure of cognitive behaviors by investigating the neural mechanisms and to make coping plans on the basis of the mechanisms, being conducted beyond the influence of Great East Japan Earthquake.
Recent clinical studies have increased to report that “working memory” was disturbed by “negative feeling.” These wits were reportedly involved in the “hippocampo-prefrontal pathway” and the “prefrontal-amygdala pathway” of rats, respectively, and worked with dopaminergic transmission in the prefrontal cortex and the amygdala. We electrophysiologically and/or neurochemically analyzed above subjects, and mainly reported relationship between behavioral property and synaptic transmission of the prefrontal-amygdala pathway in early-weaned rats.
