Heterogeneous Responses to Antioxidants in Noradrenergic Neurons
of the Locus Coeruleus Indicate Differing Susceptibility to Free Radical Content

Impact of DTT treatment in the pacemaker process of LC neurons. (a) Table demonstrating the effect of 1 mM DTT in the spontaneous firing of LC neurons and comparison of values obtained for AP before (ACSF) and 180 s after 1 mM DTT treatment ( for spontaneous firing and for AP comparison). (b) Averaged APs demonstrating comparison before (ACSF) and after 180 s after 1 mM DDT treatment (). Hyperpolarizing group was excluded from comparison demonstrated in (a) and (b) due to lack of APs at 180 s treatment. (c) and (d), Example for recordings demonstrating the two minor effects induced by 1 mM DTT where neurons hyperpolarized and ceased firing (c) and stopped firing without hyperpolarization (d) ().
