| Outline of Final Research Achievements |
Neuregulin (NRG) and epidermal growth factor (EGF) have various influences on phenotypic and synaptic development of neocortical GABAergic neurons during postnatal period. Administered animals with these factors as neonate exhibit behavioral abnormalities related with schizophrenia in adulthood. Though many animal models for neuropsychiatric diseases exhibits functional abnormalities of GABAergic function, it is not so far analyzed in adult EGF/NRG-treated animals. Here, in vivo GABAergic function, evaluated with gamma oscillation of electroencephalogram, spike firing and channel properties, and neurochemical property of fast-spiking neurons were analyzed in frontal cortical areas of these models. Results of these analyzes suggest that perturbations of EGF/NRG signaling during neonatal period induce functional impairments of fast-spiking neurons in medial prefrontal cortex, which more prominently appeared in adulthood.
