1
Q

LTP is a proposed formation of consolidation of memories through what formation?

A

Hippocampus formation

2
Q

LTD is proposed to be responsible for motor learning through what circuitry?

A

Cerebellar cortical circuitry

3
Q

What is the guidance system for neuronal migration

A

Radial glial cells

4
Q

This synaptogenesis mechanism involves the growth toward negative pole in voltage variable environment. E-stim can be used to help aid this mechanism.

A

Galvanotropism

5
Q

This synaptogenesis mechanism involves spatial and chemospecific parts. This is a functional validation of the best suited wins

A

Competition

6
Q

This occurs after some pre-synaptic terminals are lost, result in an increase in neurotransmitter release from the unmanaged pre-synaptic terminal

A

Synaptic hyper-effectiveness

7
Q

In response to vacated synapses, adaptive changes occur to other synapses in the area. Increase in density of receptors in postsynaptic membrane. (Happens in BG of Parkinson’s Disease)

A

Denervation hypersensitivity

8
Q

Where is axonal regeneration occur in the human??

A

NOT the CNS

1mm/day in the PNS

9
Q

This type of axonal reorganization occurs when sprout from the injured axons start growing out within several days of the injury?

A

Axonal regeneration

10
Q

This type of axonal reorganization occurs when surviving neurons that innervated the same target organ are somehow stimulated to send out collateral branches from their axons to reinnervate the denervated target cells?

A

Collateral Sprouting

11
Q

What are the disadvantages of collateral sprouting?

A

May create abnormal connections and may be responsible for spasticity
