Flashcards in Neuroplasticity Deck (10):
1

Define neuroplasticity

ability of nervous system to reorganize/rewire its structure and function in response to internal or external stimuli

2

Define long term potentiation

LTP is a long lasting strengthening of a synaptic connection that occurs with repeated stimulation

3

What two receptors does glutamate bind to? What is their effect?

AMPA and NMDA
Depolarization

4

What are the 3 effects of LTP on a synaptic level?

Phosphorylation of AMPA receptors
Creation of new AMPA receptors
Sprouting of dendrites

5

Define long term depression

Reverse process that can weaken the efficacy of the synapse

6

What is the neuroplasticity derived proposed therapy for stroke?

Constraint induced therapy

7

What are the three areas involved in pleasure control?

Prefrontal cortex inhibits nucleus accumbance
Nucleus accumbance stimulates ventral tegnmental area to release dopamine

8

What is the effect of continued use of drug/addiction?

loss of inhibition of prefrontal cortex

9

What are the two types and subtypes of transcranial magnetic stimulation?

Single TMS, multiple TMS
Multiple: high frequency--> stimulates
Low frequency--> supresses

10

What are the possible side effects of TMS?

Some case reports of seizures
