Figure 5. Intrinsic and synaptically driven excitability of FS cells are unaltered by deprivation.

Figure 5

(A) Current-firing rate relationship for FS cells, for 500-ms current injection. Rheobase is the current required to elicit a single spike. Scale bar: 40 mV, 200 ms. (B) Intrinsic properties of FS cells in deprived vs. sham-deprived D columns. Tau is the membrane time constant. (C) Left, experimental design to measure the L4-evoked excitatory conductance required to elicit 50% spike probability in an FS cell. Right, consecutive sweeps showing L4-evoked spikes recorded in cell-attached mode from an FS cell at 50% spike probability. Scale bar: 50 pA, 10 ms. (D) Peak and integrated Ge at 50% spike probability (integrated from response onset to spike latency for each neuron) for cells from deprived vs. sham-deprived rats. See also Figure S2.
