Neuronal physiology refers to the biology of neuronal function, including an understanding of the molecular and cellular processes that underlie neuronal activity.
Snyder et al. report that hippocampal neurons in Egyptian fruit bats modulate their activity depending on the position and identity of human experimenters when bats are flying and encode experimenter position and identity when bats are stationary.
Whole-cell recordings of retinal ganglion cells responses to high-frequency stimulation (HFS) revealed that membrane depolarization mediates both inhibition and preferential activation. The results indicate that understanding ion-channel dynamics is crucial for improving HFS-based stimulation.
A new biotinylation-based approach identifies previously unknown cell surface proteins of the axonal initial segment (AIS) and shows a role for contactin-1 in assembly of the AIS extracellular matrix.
