Q

Somatosensory Cortex

A

Process incoming sensory information

19
Q

What happens when a body area is more sensitive

A

If a body area is more sensitive a larger of the somatosensory cortex is devoted to it

20
Q

When does the pre frontal cortex develop

A

Not fully developed until 20-25 years of age

21
Q

Motor cortex

A

Initiates motor movements

22
Q

What does damage to Broca’s area do (Language production)

A

causes language impairment

22
Q

What side of the brain is language

A

Language is in the left side of the brain

23
Q

What does aphasia in Wernickkes area cause (speech comprehension)

A

causes a lack of comprehension but not production of speech

24
Q

Aphasia

A

The loss of ability to understand speech/language

25
Q

Contralateral organization

A

Left hemisphere controls right side of the body and vice versa

26
Q

Cell body (Neurons)

A

Coordinates information processing and keeps cell live

26
Q

Dendrites (Neurons)

A

Receives information from other neurons and relays it to the cell body

27
Q

Axon (Neurons)

A

Long slender projection that conducts electrical impulses away from cell body

28
Q

Synapse (Neurons)

A

The region between the axon of one neuron and dendrite of another

29
Q

Myelin Sheath (Neurons)

A

Fatty sheath that insulates axon resulting in increased speed of and efficiency of neural communication

30
Q

How do neurons send and receive messages

A

When a neuron is at rest / resting potential

31
Q

What happens when the axon is stimulated

A

Depolarization when stimulated sodium channels open and + ions rush in

32
Q

Repolarization

A

After the sodium gates closes. Potassium moves out

33
Q

Actional potential

A

An electrical signal is conducted along the length of a neuron’s axon to synapse

34
Q

Synaptic Cleft

A

When the action potential reaches the terminal buttons it causes the release of neurotransmitters into the synaptic cleft

35
Q

Excitatory

A

increase the likelihood of an action potential (by causing the membrane potential to be less negative)

36
Q

Inhibitory

A

decrease the likelihood of an action potential (by causing the membrane potential to be more negative)

37
Q

Acetylcholine

A

Involved in a number of functions including voluntary motor control

38
Q

Dopamine

A

Regulates motor behavior, motivation, pleasure and emotional arousal

39
Q

What happens if there is degeneration in Dopamine

A

Degeneration of these neurons in a particular part of brain linked to parkinson’s disease

40
Q

Serotonin

A

Involved in regulating sleep and wakefulness and eating behavior

41
Q

Agonist

A

drug that increases the action of neurotransmitter

42
Q

Antagonist

A

Drugs that diminishes the function of neurotransmitter
