Figure 3. Isolated thalamic inputs exhibit weak correlation during ongoing activity.
(a) Simultaneous whole cell recordings of two putative excitatory L4 cells during ongoing activity in current clamp and voltage clamp (at the reversal potential of inhibition) modes recorded in anaesthetized mouse. (b) Example traces of ongoing excitatory currents in two simultaneously recorded L4 cells during LED OFF and LED ON conditions. Upper insets, average excitatory responses to whisker stimulation. Lower insets, cross-correlation between the cells. (c) Population CC values for L4–L4 pairs n=10, P=0.002, Wilcoxon signed-rank test) and L4–L5 pairs n=6, P=0.0313, Wilcoxon signed-rank test). Example pair in b is depicted in red.
