Circadian Modulation of the Cl− Equilibrium Potential in the Rat Suprachiasmatic Nuclei

is shifted from the estimated from the Nernst equation in subpopulations of the SCN neurons recorded in whole cell configuration. At an estimated of −30 mV, the dorsal SCN neurons recorded during the day showed an of mV (a), while in ventral SCN the predominant is − mV (b), close to the hypothetical equilibrium potential. At an estimated of −60 mV, when recorded during day, the predominant GABAergic sPSCs equilibrium potential in the dorsal SCN was − mV (c), while in the ventral SCN was − mV (d). Conversely, during the night, the predominant equilibrium potential in the dorsal SCN was − mV (e) and in the ventral SCN was − mV (f).
