Neuronal mechanisms for the perception of ambiguous stimuli.

abstract：:Feeding history and the presence of food dramatically alter chemosensory behaviors. Recent results indicate that internal nutritional state can gate peripheral gustatory and olfactory sensory responses to affect behavior. Focusing primarily on recent work in C. elegans and Drosophila, I describe the neuromodulatory me...

abstract：:Recent studies suggest that endocannabinoids act as retrograde messengers at many synapses in the central nervous system. Activation of phospholipases, either through calcium-mediated or receptor-mediated signaling, leads to the formation and release of endocannabinoids. These lipophilic signaling molecules diffuse to...
