Bilateral deep brain stimulation of the subthalamic nucleus increases pointing error during memory-guided sequential reaching.

abstract：:Extracellular recordings were made from neurones in the ventromedial and parafasicular nuclei of the rat thalamus, many of which had demonstrable capsular or caudate projections. These cells responded to electrical stimulation of the ipsilateral substantia nigra with a short latency (4 ms) inhibition presumed to be mo...

abstract：:Emotional memory consolidation has been associated with rapid eye movement (REM) sleep, and recent evidence suggests that increased electroencephalogram spectral power in the theta (4-8 Hz) frequency range indexes this activity.
