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

Interactions Between Paired-Pulse Facilitation, Low-Frequency Stimulation And Behavioral Stress In The Pathway From Hippocampal Area CA1 To The Subiculum: Dissociation Of Baseline Synaptic Transmission From Paired-Pulse Facilitation And Depression Of The Same Pathway.

Here’s an old and difficult to access paper (Download: Commins & O’Mara Psychobiol) of ours from Psychobiology – from the days before all journals were online. Hard to remember those days now… Psychobiology evolved into Cognitive, Affective, & Behavioral Neuroscience (see past titles here – scroll to bottom). (This is the longest title on any paper I have ever published…) Commins,… Read More
