Decoding signal processing in thalamo-hippocampal circuitry: implications for theories of memory and spatial processing.

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
