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...

Orexin A/hypocretin-1 selectively promotes motivation for positive reinforcers.

7 Sep 2009 Orexin A/hypocretin-1 (oxA/hcrt-1) is known to be a modulator of dopamine-dependent neuronal activity and behaviors. However, the role of this system in driving motivated behaviors remains poorly understood. Here, we show that orexin/hypocretin ... Read more...

The role of serotonin in nonnormative risky choice: the effects of tryptophan supplements on the "reflection effect" in healthy adult volunteers.

30 Aug 2009 Risky decision-making involves weighing good and bad outcomes against their probabilities in order to determine the relative values of candidate actions. Although human decision-making sometimes conforms to rational models of how this weighting is ... Read more...
