Alteration of theta timescale dynamics of hippocampal place cells by a cannabinoid is associated with memory impairment.

5 Oct 2009 The integrity of the hippocampus is critical for both spatial navigation and episodic memory, but how its neuronal firing patterns underlie those functions is not well understood. In particular, the modality by which hippocampal place cells ... Read more...

Prenatal phencyclidine exposure alters hippocampal cell proliferation in offspring rats.

30 Aug 2009 Multiple case reports have described pregnancy in phencyclidine hydrochloride (PCP) abusers. Characteristic clinical symptoms of PCP-exposed infants have revealed neurobehavioral or physical abnormalities. We designed this study to evaluate whether ... Read more...

Cannabinoid modulation of hippocampal long-term memory is mediated by mTOR signaling.

31 Jul 2009 Cognitive impairment is one of the most important negative consequences associated with cannabis consumption. We found that CB1 cannabinoid receptor (CB1R) activation transiently modulated the mammalian target of rapamycin (mTOR)/p70S6K pathway and ... Read more...
