Figure 2. Dual whole‐cell voltage recording from a pyramidal cell in a brain slice.

A, pyramidal cell and two pipettes recording membrane voltage from the soma and apical dendrite, respectively, of the same cell. B, verification of dual whole‐cell recording by filling a neuron with two different fluorescent indicators, blue and yellow, via two whole‐cell recording patch pipettes at the soma and apical dendrite of the same cell.
