Membrane characteristics and excitability of CRF1⁺ and CRF1⁻ lateral amygdala neurons. A, Summary of membrane characteristics of CRF1⁺ (n = 28) and CRF1⁻ (n = 28) LA cells. B, Representative current-clamp recording of LA CRF1⁺ neuron action potentials elicited by 100 pA current injection (top) and the relative proportion of CRF1⁺ LA neurons displaying spike accommodation with current injection (bottom). C, Representative current-clamp recording of LA CRF1⁻ neuron action potentials elicited by 100 pA current injection (top) and the relative proportion of CRF1⁻ LA neurons displaying spike accommodation with current injection (bottom). D, Summary of rheobase at −70 mV (left) and the threshold to fire (right) of CRF1⁺ and CRF1⁻ LA neurons. *p < 0.05 by unpaired t test comparing CRF1⁺ to CRF1⁻ cells. E, Summary of action potentials by current injection in CRF1⁺ and CRF1⁻ LA neurons.
