(A) Experimental design for measuring dCA1 neuronal excitability.
(B) Representative traces showing adaptive firing responses to a 200pA current injection in dCA1 pyramidal neurons.
(C) Inhibition of LC cells projecting to dCA1 during context exploration reduced the firing rate of dCA1 neurons 5 hours later (Two-way repeated measures ANOVA; control n=15, LC inhibited n=15, #p<0.05). Clozapine-N-oxide was given to all mice. # is used to show significance between groups for two-way RM ANOVA.
All results are mean + s.e.m.
