A novel local circuit in the olfactory bulb involving an old short-axon cell.
Many local circuit interactions in the olfactory bulb involve atypical dendrodendritic synapses. In this issue of Neuron, Pressler and Strowbridge report a functional analysis of a class of short-axon interneurons in the bulb called Blanes cells. Blanes cells make GABAergic axonal contacts onto granule cells and may mediate a form of local feedforward disinhibition.
