Noradrenergic modulation of spontaneous activity in BLA neurons is altered after fourteen days of chronic cold exposure, but not seven. A) Example of a neuron from a control rat showing an inhibition in spontaneous activity during microiontophoresis of NE. B) Example of a neuron from a 14 day cold-exposed rat displaying an excitation of spontaneous activity during microiontophoresis of NE. C) Neurons from control rats and rats exposed to seven days of cold showed primarily inhibitory responses to NE, however in rats exposed to 14 days of cold, more neurons display excitatory responses to NE.
