Flashcards in Q7 Deck (10):
1

T/F: The neuron in the Site of Impulse Initiation Tutorial is the simplest computational type of computational representation of a neuron.

True

2

In the Site of Impulse Initiation Tutorial, is the dentrite isopotential?

No

3

The neuron's morphology per se causes the spike to initiate in the axon in a region close to what part of the axon?

The soma

4

Evidence suggest that there may be a greater density of what in the region close to the soma?

Na channels

5

In the Synaptic Integration tutorial, the channel densities are matched to experimental observations in the spinal motoneuron of what animal?

Cat

6

T/F: The amount of current is the important factor in whether a neuron will depolarize enough to initiate an action potential.

True

7

What lizard preparation was used in the Impulse Invasion of the Presynaptic Terminal tutorial?

Bouton-type neuromuscular junction

8

What technique did Lindgren and Moore (1989) use to record currents from lizard presynaptic terminals?

Loose patch

9

How has nature ensured that an action potential can invade a myelin-free presynaptic arbor despite increased capacitive load?

Short arbor branches

10

What is the other factor for ensuring an action potential?

High Na channel density
