Oscillatory entrainment of thalamic neurons by theta rhythm in freely moving rats.

Take-home message: The thalamus plays a key role in  learning and memory. However, the neurons of the anteroventral nucleus have not been characterised in vivo. Here, we provide a framework for the classification of neuron type, based on their electrophysiological phenotype, and show that many of these cells are theta-modulated (a strong 7-12 Hz oscillation in the EEG, studied most frequently in… Read More

Theta-modulated head direction cells in the rat anterior thalamus.

Take-home message – two key findings: (1) there are head-direction cells in the anteroventral thalamus (head direction cells fire when the head is pointed in a particular orientation); (2) a large fraction of these cells are theta-modulated (a strong 7-12 Hz oscillation in the EEG, studied most frequently in the hippocampal formation). These data are interesting because they suggests that the anterior thalamus… Read More
