Properties of piriform cortex pyramidal cell dendrites: implications for olfactory circuit design.

5 Oct 2009 Unlike the neocortex, sensory input to the piriform cortex is anatomically segregated in layer 1, making it ideal for studying the dendritic integration of synaptic inputs pivotal for sensory information processing. Here we investigated dendritic ... Read more...

Naloxone, but not flupenthixol, disrupts the development of conditioned ejaculatory preference in the male rat.

29 Sep 2009 Male rats display a conditioned preference to ejaculate with a female bearing an odor paired previously with copulation to ejaculation. The present study examined the role of endogenous opioid and dopamine systems in this preference. Male rats ... Read more...

Acute illness induces the release of aversive odor cues from adult, but not prepubertal, male rats and suppresses social investigation by conspecifics.

29 Sep 2009 The present study examined odorant communication during acute illness provoked by injection of lipopolysaccharide (LPS; 100 microg/kg) and how these effects vary between prepubertal and adult conspecifics. Exposure to odor of LPS-treated adult male ... Read more...
