6. what does the superior colliculus do
- relay information to other areas
- co ordinate fast responses eg eye movements
- regulate breathing
7. what is intracellular transmission
8. other brain cells aside neurons
- glia (microglia, oligodendrocytes, astrocyte)
- blood supply
- pyramidil
9. where does csf exist
- in ventricles
- in subarachnoid space between meninges
- in spine
10. what does spinal white matter do
- transport ascending / descending
- reflexes and pain regulation
- processing
11. what happens after sodium gated channels open
- they shut and potassium gated channels open causing + to leave and repolarising
- they remain open
12. what does autonomic nervous system branch onto
- pain, parasympathetic and sympathetic
- central
- perhiperal
- somatic
13. What is Na+
- Chloride
- Sodium
- Potassium
14. how is nerve conduction different to wire conduction
- ~100ms slower
- ~50ms slower
- ~50ms faster
15. What is Cl
- Sodium
- Chloride
- Potassium
16. what does the thalamus do
- gates relays and modifies info
- processes emotions
- sequences fast movements
17. what happens after potassium gated channels open
- more potassium leaves than normal because more channels open than normal and hyperpolarisation
- it balances out
- the cycle repeats
18. where does most of the output from the cerebral cortex go
- to motor outputs
- to the cerebral cortex
- to the central nervous system
19. what nervous system processes the input
- autonomic
- central
- peripheral
- somatic
20. what do brainstem nuclei do
- relay information to other areas
- create certain neurotransmitters
- process emotions
