Head direction (HD) cells, found in the rodent Papez circuit, are thought to form the neural circuitry responsible for directional orientation. Because NMDA transmission has been implicated in spatial tasks requiring directional orientation, we sought to determine if the NMDA antagonist dizocilpine (MK-801) would disrupt the directional signal carried by(More)
Head Direction (HD) cells of the rodent Papez circuit are thought to reflect the spatial orientation of the animal. Because NMDA transmission is important for spatial behavior, we sought to determine the effects of NMDA blockade on the basic directional signal carried by HD cells and on experience-dependent modification of this system. In Experiment 1, HD(More)
