Document Summary
Lecture 10 convergence, divergence and lateral inhibition. Last time, we were talking about these neuromodulatory systems, which originate in the brainstem and then project up into the cerebral cortex and all over the thalamus and . These ascending arousal systems that originate in the brainstem and project up to. This is reflecting the fact that the neurons in the cortex are synchronized together, (doing different things, they cancel out) certain region of the cerebral cortex. Eeg recording technique, you"re recording from 1000 of neurons distributed over a. When you drift into sleep, the initial stage of sleep is called slow wave sleep , they are firing together, and that"s why the amplitude gets big. Secondly, they"re firing in these rhythmic bursts, it"s like the cortex is sort of. The eeg has the same look as when you"re awake. After a while, you drift into the next stage of sleep which is called the rem sleep.
