Document Summary

Acetylcholinergic neurons are located in the dorsal pons, the basal forebrain and in the medial. Acetylcholinergic neurons: acetylcholine (ach, neorepinephrine (ne, serotonin (5-ht, histamine, hypocretin. Acetylcholinergic neurons agonists decrease and increase cortical arousal, respectively (as measured by eeg activity). are located in the dorsal pons, the basal forebrain and in the medial septum. Neural control of arousal: acetylcholine (ach): septum: ach antagonists and agonists decrease and. Ach release in striatum, hippocampus and frontal cortex is agonists decrease and associated with animals level of arousal (as measured by increase cortical arousal, microdialysis). respectively (as measured by eeg activity). Electrical stimulation of the dorsal pons region activates and stimulates ach release in cerebral cortex. This can be be blocked by deactivating cholinergic neurons in the basal forebrain. increase cortical arousal, respectively (as measured by eeg activity: ach release in striatum, hippocampus and frontal. This can be blocked by deactivating stimulates ach release in cerebral cortex.
