Synchrony in RB-ET cells ramifying
in the same glomerulus
Whole-cell
current clamp paired recording from 2 External Tufted cells filled with
biocytin and reconstructed using NeuroLucida software (middle right panel).
First panel shows a sample of 5 sec recording of membrane potentials: the
blue and red superimposed traces correspond to recording from the 2 neurons
drawn in red and blue, respectively. Note that the 2 neurons fire bursts of
action potential either together or alone. The 2 neurons exhibited highly
synchronous membrane potential oscillations and bursting as also indicated by
the cross-correlogram. The coefficient of correlation at zero time lag was C
= 0.56
