Individual and morphological differences in the behavioural response to apomorphine in rats.

abstract：RATIONALE:Endogenous γ-aminobutyric acidA receptor (GABAAR)-active neurosteroids (e.g., allopregnanolone) regulate central nervous system excitability and many physiological functions, so fluctuations are implicated in several neuropsychiatric disorders. Pertinently, evidence supports an inverse relationship between en...

It is known that cannabinoid CB1 agonists reduce sensorimotor gating in rats, suggesting that the CB1 receptor and the cannabinoid system are involved in sensorimotor gating. OBJEC...
