- Shh (high levels at ventral floor)
- What four signals are involved in the A/P axis formation?
- Wnt, BMP, retinoic acid, FGF
- What ECM molecule is involved in migration?
- main one: Reelin
- What are ApoE and VLDL receptors involved in?
- cortical development
- What happens if megalin is knocked out?
- holoprosencephaly- LDL receptor
- blocks Na channels
- What is the cause of Charcot-marie tooth disease?
- loss of peripheral axons due to demyelination
- in high doses blocks GABA receptors
- methylasomethanol- causes neuromigratory problems (heterotopias- Kv4.2)
- K channel blocker
- RCK loop?
- regulatory domain involved in K conductance also has neg. charged aa.
- what channel has constitutively bound calmodulin?
- acetylcholinesterase inhibitor
- irreversibly binds antibody in MG against AchR (nicotinic)
- blocks nicotinic AchR
- Ca sensor for fusion of vesicles
- What are the Small MW NT (4 groups)?
2.A.A.- Glutamate, GABA, glycine

- benzodiazepines, barbituates, alcohol
- GABA antagonist?
- ketamine and PCP?
- NMDA antagonist
- amphetamines with respect to both Dop and NE?
