Figure 4.
Effect of inactivating the BLA with TTX on VTA DA neuron
activity. Histological slice showing track of the guide cannula in the
BLA (A). Coronal brain section adapted from (Swanson, 2018) (VEH: black
dots; TTX: white and black dots) (B). Number of spontaneously active DA
neurons recorded per electrode track (C, left), number of spikes per
second (firing rate; C, middle) and percentage of action potential
firing in bursts (C, right) in cocaine WD26-45 rats after VEH or TTX
infusion in the BLA. Data are mean ± SEM; *p<0.05; cocaine
WD26-45 VEH: 7 rats, 32 neurons; cocaine WD26-45 TTX: 6 rats, 50
neurons. Coronal brain sections adapted from (Swanson, 2018).
