Laminar patterns of excitatory and inhibitory input to burst-spiking cells. A, B, Example maps of excitatory and inhibitory input from a BS cell (for morphological and electrophysiological features of BS cells, see supplemental Fig. S2G–I, available at www.jneurosci.org as supplemental material). C, D, Summary data of laminar input strength (mean ± SE; %EI), calculated from eight excitatory input maps and nine inhibitory input maps from BS cells. Scale bars, 100 μm. Conventions are as in previous figures.
