Lots of thinking on consciousness and what it’s about around at the moment: some comments and links

There’s lots of interesting work around on the psychology, neuroscience and philosophy of consciousness at the moment, including issues to do with volition and free will. I sometimes make the observation to my students when we discuss consciousness and the brain that ‘our consciousness is at the centre of almost all that matters to us as humans,… Read More

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
