The effect of insulin on different types of pyramidal neurons. (A) Histogram of burst index for SP and SL. (B) Comparison of RMP between SP and SL [unpaired t-test, n = 20 and 18, t₍₃₆₎ = 2.67, P = 0.01]. (C–E) Comparison of effects of insulin on SP and SL for ISI [C, unpaired t-test, n = 20 and 18, t₍₃₆₎ = 1.12, P = 0.27], latency [D, unpaired t-test, n = 20 and 18, t₍₃₆₎ = 0.13, P = 0.90], and RMP [E, unpaired t-test, n = 20 and 18, t₍₃₆₎ = 0.81, P = 0.42], respectively. The error bars represent mean ± SE.
