a. True
b. False

A

B
Neurons are individual cells composed of dendrites, cell body, axon and terminal buttons. Nerves, on the other hand, are bundles of neuron fibers (axons) which transmit signals over some distance. Both comprise the nervous system.

Q

The more active the neurons, the more neurotrophins generate and the better they respond
a. True
b. False

A

A
Learning increase neural activity which in turn regulated specific molecules that are produced and secreted by neurons to act as a brain nutrient that can promote their health (neurotrophins). The more active the neurons, the more neurotophins generate and the better they respond.

A

19
Q

Glutamate is necessary for
long-term potentiation to occur.
a. True
b. False

A

Glutamate is deemed as no longer required for long-term potentiation to occur as previously thought

20
Q

The prefrontal cortex remains underdeveloped until the age of 25.
a. True
b. False

A

A

21
Q

Action potential occurs when
neural communication takes the form of electrical transmission within the length of the neuron.
a. True
b. False

A

A
Involves electrical signals (action potentials) along axons to achieve long distance and rapid communication

22
Q

When we try to rest by sleeping,
our brain also rests and becomes idle momentarily.
a. True
