Sex- and diet-dependent responses to bath application of 12.5 nM insulin in CA1 pyramidal neurons from male rats. a Averaged AHP traces are shown from CD (insulin-sensitive) neurons and HFD (insulin-insensitive) male neurons. b Bath application of insulin significantly reduced peak AHP amplitudes in CD but not HFD neurons. c AHP durations were significantly reduced in CD neurons, but not in HFD neurons. d While mAHP and sAHP measures were significantly reduced by insulin in neurons from CD rats, both mAHPs and sAHPs from HFD rats were insulin-insensitive. *p < 0.05
