Topic: thalamo-cortical projections

During sleep, memories formed in the hippocampus when awake are progressively transferred to the neocortex, where they are reorganised and stabilised to become long-term memories. This consolidation process is believed to occur concurrently with neuronal oscillations such as sleep spindles. Spindles are waxing-and-waning oscillations in the 10-16 Hz frequency range recorded from the brain's surface, originating in the thalamus and transmitted to the neocortex via thalamo-cortical projections. Several types of spindles have been identified, but how they are linked to specific consolidation proc
