Systematic morphological and morphometric analysis of identified olfactory receptor neurons in .

The biophysical properties of sensory neurons are influenced by their morphometric and morphological features, whose precise measurements require high-quality volume electron microscopy (EM). However, systematic surveys of nanoscale characteristics for identified neurons are scarce. Here, we characterize the morphology of olfactory receptor neurons (ORNs) across the majority of genetically identified sensory hairs.
