Question 1

What is Multiple Sclerosis (MS)? Describe some of the common symptoms and 4
types.

Question 2

How does a damaged neuron look in MS patients?

Question 3

Describe the process of a neuron firing starting from when it receives neurotransmitters from a neighboring cell to its release of its own neurotransmitters.

Question 4

What are the input, trigger, conducting, and output signals during neural
transmission?

Question 5

What is the resting voltage of a neuron and what decides whether it fires?

Question 6

What is hyperpolarization and what are the possible refractory periods?

Question 7

When do neurons influence each other (summations of inputs) and what are EPSPs and IPSPs?

Question 8

How do neurons change?

Question 9

Describe epigenetics and neuronal changes.

Question 10

Describe on way that life can influence gene expression can influence brain/mental health.

Question 11

What is backpropagation?

Question 12

What is synaptic pruning?

Question 13

Describe the mechanisms of neuroplasticity.

Question 14

What imaging technique(s) can we use to record electrical activations?

Question 15

What imaging technique(s) can we use to see soma activations (grey matter)?

Question 16

What imaging technique(s) can we use to see axon activations (white matter)?

Question 17

What are the main differences between single-cell recordings and EEG?

Question 18

What imaging technique(s) can we use to record brain structures?

Question 19

What are the hemodynamic response, assumption, and delay?

Question 20

What are the main differences between fMRI and fNIRS?

Answer 21

7t
