To move or not: Previous experience in a runway avoidance task determines the appearance of hippocampal Type 2 sensory processing theta

Rats in a runway avoidance task responded to a test shock probe with a period of immobility lasting from 2 to 6 s. The shock avoidance-trained group displayed hippocampal theta during the immobility response. The inescapable shock group, in contrast, displayed large amplitude irregular activity (LIA...

Description
Summary:Rats in a runway avoidance task responded to a test shock probe with a period of immobility lasting from 2 to 6 s. The shock avoidance-trained group displayed hippocampal theta during the immobility response. The inescapable shock group, in contrast, displayed large amplitude irregular activity (LIA). Following reversal training to escapable shock, all shock avoidance-trained rats responded with LIA and inescapable shock trained rats, reversed to shock avoidance, displayed theta.
