feedback to motor cortex
what are the 4 nuclei of the reticular acitvating site
raphe nucleus
ventral tegmental
locus correoleus
basal forebrain- nucleus of myhert
what neurotransmitter is from the raphe nucleus
sertonin
what are the seretonergic connections from the raphe nuclues
pontomedullary neurones project to the spinal cord for the modualtion of slow pain
rostral pons projects to thalamus, limbic system and cerebral cortex
what is the seretonergic pathwya involved in
sleep wake, mood and emotional behaviors
what neurotransmitter is from the basal forebrain(nuc of meynert)
ach
where do cholinergic axons project from
pontomesoencephalic tegmental neurones to the thalamus
from basal forebrain nuclei (nuc of meynert) and hypothalmus project to hte cerebral cortex
what the major role of the projections of the nucleus of meynert
cortical excitability
memory and learning
where are dopaminergic projections frm
the ventral tegmental area
where do dopaminergic projections go
accumbens srtiatum prefrontal cortex and limbic system
what does the mesocorticolimbal system do
plays a major role in motivation, reward, addiction, depression
where do noradrenergic axons project from
loceus cerelues
where do nor adrenergic axons project to
cerebral cortex, thalmus, hypothalamus, cerebellum brainstem and spinal cordd
what are the nor adrnerrgic pathways involved in
regulation of attention, cortical arousal, learning and memory, anxiety and mood plus the sleep wake cycle
