Topic: TH/GFP+ cells

Sensory systems deploy diverse strategies for discriminating similar stimuli. For instance, spatially isotropic lateral inhibition between neurons showing overlapping receptive fields allows contrast enhancement of primary stimulus representations in the visual system. In the olfactory bulb (OB), odorant identity is primarily represented as a spatially discontinuous map of activated glomeruli. Prior observations on mixture inhibition across glomeruli led us to hypothesize that so-called superficial short-axon-cells -a sub-population of GABAergic/dopaminergic juxtaglomerular cells- underlie a t
