Popis: An electroencephalographic (EEG) and behavioral model of head injury in unanesthetized, free moving mice has been used to test the effects of TRH and GM1. In our experimental conditions a mechanical head injury capable of including loss of righting reflex for 2 to 60 sec, also induces a consistent decrease of the total power of the spectrum of EEG and a decrease of the power of fast beta band (20–40 Hz) for at least 120 min. TRH, injected after trauma in dose of 10 mg/kg, caused improvement of EEG total power of the spectrum. GM1 in high (30 mg/kg) but not in low dose (5 mg/kg) caused more rapid restoration of both the total power and fast as well as slow beta band power. These results suggest that GM1 has favorable effects on post-concussive neurophysiological symptoms in head injured animals.
