Neurons in layer II of the entorhinal cortex (EC) are key elements in the temporal lobe memory system because they integrate and transfer into the hippocampal formation convergent sensory input from the entire cortical mantle. EC layer II also receives a profuse cholinergic innervation from the basal forebrain that promotes oscillatory dynamics in the EC network and may also implement memory fu...

Delayed and anomalous rectification was studied in inferior olivary (I.O.) neurons in guinea pig brain stem slices maintained in vitro. Hyperpolarization of the I.O. cell beyond rest membrane potential was accompanied by anomalous rectification (AR). This consisted of 2 parts: an instantaneous and a time-dependent component. The "instantaneous" component was blocked by bath addition of Ba2+ or ...
