|
NoradrenaLine is one of the four monoamines; with cell bodies of the NA pathways in brain in pons & medulla where are the respective clusters |
LC Locus coeruleus (pons) LTC Lateral tegmentum (of brainstem reticular formation) |
|
|
|
The reticular formation is the neuronal core of the brainstem & has 3 main "zones" |
Lateral (predominantly sensory) Medial (predominantly motor) Raphe nuclei (serotonergic) |
|
|
|
NA transmission is believed to be important in arousal (wakefullness/alertness); blood pressure regulation; control of mood (low NA=>depression). Where do the NA pathways run? |
NA pathways from locus coeruleus & LTA project to cortex, Hippocampus, thalamus, hypothalamus & cerebellum. They do not form succinct contacts, rather being released diffusly |
NMMT |
|
|
There are 4 main dopaminergic pathways. Name these & where the respective cell bodies are located? |
Nigrostriatal- substantia nigra Mesolimbic-VTA Mesocortical- VTA Tuberohypphyseal- Hypothal |
|
|
|
Seritonin pathways are widespread (similar to NA projections). Where are the nuclei located? |
Raphe (midline) nuclei in pons & upper medulla |
|
|
|
Seritonin pathways are widespread (similar to NA projections). Where are the nuclei located? |
Raphe (midline) nuclei in pons & upper medulla |
|
|
|
Serotonin nuclei are located in the Raphe nuclei in pons & upper medulla. What functions are associated with serotonin pathways? |
-various behavioural responses (incl hallucinations) -feeding behaviour -mood & emotion -control of sleep/wakefulness -control of body temp! -vomiting |

|
What Neurotransmitter has its main cell bodies located in the Nucleus of meynart (basal frontal cortex) |
Ach |
|
|
|
Cholinergic Nuclei in the "nucleus of meynard"(Nucleus Basalis-ventral forebrain) project to the cortex. Degeneration of these nuclei is associated with what illness? |
Alzheimers disease is associated with the degreneration of cholinergic neurons in the forebrain and specifically the nucleus of meynart. |
