Q

What is the definition of behavioural neuroscience?

A

The use of biology to study the physiological mechanism that is responsible for human behaviours.

2
Q

What was ancient Egypt’s view of the brain?

A

they would take heart and liver, take out of the body preserve it and put it back- not the brain. Though they recognized that it was partly responsible for movement and stuff, they didn’t think it had anything to do with the mind.

3
Q

What did Cajal discover and how?

A

he used black room chemicals to stain part of the brain- found out units - neurons.

4
Q

_____ ____ is how neurons communicate through the network.

A

neural transmission

5
Q

The _____ neurons travels from the muscles to the brain.
The _____ type of neurons travels from the brain to the muscles.
_____ are responsible for the connections between the neurons.

A

sensory
motor
interneurons

6
Q

The dendrites send the signals to the ____.
The soma ___ the signal and makes a ____.
The _____ signals away from the soma.
The ____ ___ insulates the axon with ___ and ___ to make the signal faster.

A

Soma
processes decision
axon
myelin sheath - fat and protein

7
Q

To study axon’s scientist used an animal, what was it and why did they use this one even though it was hard to find?

A

giant squid

cause huge axon

8
Q

What discovery was made with the axon of the giant squid?

A

electrical signals are sent down the axon

Q

We say that the action potential is an __________ law, because if it doesnt reach ___mV, the action doesnt tak place.

A

all-or-none

40

12
Q

the third phase is called the ____ ___ ___ phase, because while one section ______ (more ____ ions), it stimulates the next section. Then the neurons will ____ to reach the next step.

A

spreading action potential
depolarizes
positive
repolarize

13
Q

The last step is called the ___ ____ ___. The neurons will be, for a short period, ______, which means below -70mV. During this period, they ____ fire.

A

recovery period phase
hyperpolarized
cant

14
Q

The neurotransmitters needs to fit in the ____ __, like a lock and key, for the communication to occur.

A

receptor site

15
Q

Name and explain the 2 ways for a neurotransmitter to be dealt with after communication.

A

1- broken down by enzymes and trashed

2- reuptake: recycled by the presynaptic neuron

16
Q

_____ neurotransmitters are exitatory while ____ are inhibitory.

A

Glutamate

GABA
