A single sensory neuron directs both attractive and repulsive odor preferences.

23 Sep 2008 Animal behaviors are subjected to innate preferences, which are usually encoded by dedicated sensory neurons. In this issue of Neuron, Tsunozaki and colleagues show that one olfactory neuron in Caenorhabditis elegans produces two opposing ... Read more...

A behavioral switch: cGMP and PKC signaling in olfactory neurons reverses odor preference in C. elegans.

23 Sep 2008 Innate chemosensory preferences are often encoded by sensory neurons that are specialized for attractive or avoidance behaviors. Here, we show that one olfactory neuron in Caenorhabditis elegans, AWC(ON), has the potential to direct both attraction ... Read more...

Basolateral amygdala neurons facilitate reward-seeking behavior by exciting nucleus accumbens neurons.

26 Aug 2008 Both the nucleus accumbens (NAc) and basolateral amygdala (BLA) contribute to learned behavioral choice. Neurons in both structures that encode reward-predictive cues may underlie the decision to respond to such cues, but the neural circuits by ... Read more...
