Firing properties of rat lateral mammillary single units: head direction, head pitch, and angular head velocity.
Many neurons in the rat anterodorsal thalamus (ADN) and postsubiculum (PoS) fire selectively when the rat points its head in a specific direction in the horizontal plane, independent of the animal's location and ongoing behavior. The lateral mammillary nuclei (LMN) are interconnected with both the ADN and PoS and, therefore, are in a pivotal position to influence ADN/PoS neurophysiology. To fur...
متن کاملRole of the Lateral Mammillary Nucleus in the Rat Head Direction Circuit A Combined Single Unit Recording and Lesion Study
We recorded head direction (HD) cells from the lateral mammillary nucleus (LMN) and anterior thalamus (ATN) of freely behaving rats and also made bilateral lesions of LMN while recording HD cells from ATN. We discovered that the tuning functions of LMN HD cells become narrower during contraversive head turns, but not ipsiversive head turns, compared to when the head is not turning. This narrowi...
متن کاملThe Irregular Firing Properties of Thalamic Head Direction Cells
23 Head-direction cells encode an animal’s heading in the horizontal plane. However, it is not 24 clear why the directionality of a cell’s mean firing rate differs for clockwise, compared to 25 counter-clockwise head turns (this difference is known as the ‘separation angle’) in anterior 26 thalamus. Here we investigated, in freely-behaving rats, if intrinsic neuronal firing properties 27 are li...
متن کاملPassive movements of the head do not abolish anticipatory firing properties of head direction cells.
Neurons in the anterior dorsal thalamic nucleus (ADN) of the rat selectively discharge in relation to the animal's head direction (HD) in the horizontal plane. Temporal analyses of cell firing properties reveal that their discharge is optimally correlated with the animal's future directional heading by approximately 24 ms. Among the hypotheses proposed to explain this property is that ADN HD ce...
