Term
|
Definition
| This structure disrupts synchronized activity between the cortex and thalamus during wakefulness. |
|
|
Term
| Ventrolateral Preoptic Area of the Hypothalamus (VLPO) |

Term
|
Definition
| The acting out of dreams. Caused by lesions in the pons or medulla where motor inhibition is released. |

Term
|
Definition
| Disorder characterized by excessive daytime sleepiness, cataplexy, and hypnagogic and hypnopompic hallucinations. Correlates to a reduced number of orexin neurons. |
