Abstract Neurosteroids can alter neuronal excitability interacting with specific neurotransmitter receptors, thus affecting several functions such as cognition and emotionality. In this study we investigated, in adult male rats, the effects of the acute administration of pregnenolone-sulfate (PREGS) (10 mg/kg, s.c.) on cognitive processes using the Can test, a non aversive spatial/visual task which allows the assessment of both spatial orientation–acquisition and object discrimination in a simple and in a complex version of the visual task. Electrophysiological recordings were also performed in vivo , after acute PREGS systemic administration in order to investigate on the neuronal activati…
