Fear conditioning suppresses GABAergic transmission in dMHb neurons. A&B) Frequency and amplitude of spontaneous GABAergic currents in dMHb neurons of naïve [(13 cells/6 mice) and (11 cells/4 mice), respectively, for 2 and 24 hrs experiments] and FC [(9 cells/4 mice) and (13 cells/4 mice), respectively, for 2 and 24 hrs experiments] groups 2 and 24 hrs after fear conditioning. C) Light-evoked GABAergic currents in naïve and FC groups. PPR remained unaffected by the treatment, at both 50 and 100 ms intervals. Naïve: 14 cells/4 mice; FC: 14 cells/4 mice. Asterisk denotes statistical significance.
