Functional odor map heterogeneity is based on multifaceted glomerular connectivity in larval Xenopus olfactory bulb
Summary: Glomeruli are the functional units of the vertebrate olfactory bulb (OB) connecting olfactory receptor neuron (ORN) axons and mitral/tufted cell (MTC) dendrites.In amphibians, these two circuit elements regularly branch and innervate multiple, spatially distinct glomeruli.Using functional multiphoton-microscopy and single-cell tracing, we
