ILA (Infralimbic area) functionally connects to BLN (basolateral amygdaloid nuclear complex)

Bipolar electrical stimulation of the medial prefrontal cortex (electrode in infralimbic cortex, possible spread to prelimbic) reliably evoked single spikes in putative projection neurons of the lateral and basolateral amygdala in anesthetized rats; 11 responsive neurons were found in Exp 1 and 9 in Exp 2. Only units with onset latencies under 30 ms, little latency shift with increasing intensity and low jitter were kept, which the authors take as monosynaptic and not antidromic; stimulus current was titrated so that baseline evoked spike probability was about 0.5 of 50 trials (49.3 ± 3.6% before and 50.3 ± 7.6% after drug application in 6 neurons).
