Neuroplasticity

Question 1

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

Answer 1

Hippocampus formation

Question 2

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

Answer 2

Cerebellar cortical circuitry

Question 3

What is the guidance system for neuronal migration

Answer 3

Radial glial cells

Question 4

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

Answer 4

Galvanotropism

Question 5

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

Answer 5

Competition

Question 6

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

Answer 6

Synaptic hyper-effectiveness

Question 7

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)

Answer 7

Denervation hypersensitivity

Question 8

Where is axonal regeneration occur in the human??

Answer 8

NOT the CNS

1mm/day in the PNS

Question 9

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

Answer 9

Axonal regeneration

Question 10

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?

Answer 10

Collateral Sprouting

Question 11

What are the disadvantages of collateral sprouting?

Answer 11

May create abnormal connections and may be responsible for spasticity
