Slow wave sleep induction
Some of the brain regions implicated in the induction of slow-wave sleep include: • the parafacial zone (GABAergic neurons), located within the medulla oblongata • the nucleus accumbens core (GABAergic medium spiny neurons; specifically, the subset of these neurons that expresses both D2-type dopamine receptors and adenosine A2A receptors), located within the striatum Webbpossible to reliably and non-invasively induce sleep slow waves in humans was obtained by perturbing the cortex at a rate of approximately 1 Hz using transcranial magnetic …
