Answer 6

The Frontal Lobe is involved in planning, abstract reasoning, and logic

Question 7

What is the role of the Spinal Cord?

Answer 7

Transfer messages to and from the brain

Answer 8

Somatic Nervous System and the Autonomic Nervous System

Question 9

What 2 components are within the Autonomic nervous system? + Their Fuctions

Answer 9

1) Systematic Nervous System (Prepares the body for fight or flight)
2) Parasympathetic Nervous System (Relaxes the body/Slows down heart rate)

Question 10

What are the 3 types of neurones?

Answer 10

1) Motor Neurone
2) Sensory Neurone
3) Relay Neurone

Question 11

What does the cell body inculde?

Answer 11

The Genetic Material Of The Cell

Question 12

What are the six components that make a motor neurone

Answer 12

1) Dendrite
2) Myelin Sheath
3) Axon’s
4) Cell Body
5) Nodes Of Ranvier
6) Axon Terminal

Question 13

What does the Nucleus contain?

Answer 13

The Genetic Material Of The Cell

Question 14

What does the Dendrite do?

Answer 14

Receives signals from other neurones

Question 15

What does the Axon do?

Answer 15

It carries the impulses away from the cell body down the length of the neurone

Question 16

What is the purpose of the Myelin Sheath?

Answer 16

It protects the Axon and speeds up Electrical transmission of the impulse

Question 17

What do the nodes of ranvier do?

Answer 17

Helps speed up an impulse by providing gaps in the Myelin Sheath for the impulse to jump along

Question 18

What does the Axon Terminal do?

Answer 18

It Communicates with the next neurone in the chain

Question 19

What are Neurotransmitters also known as?

Answer 19

The brains chemical messangers

Question 20

What is the Endocrine System?

Answer 20

A network of glands across the body that produces chemical messages called hormones that regulate many bodily functions

Question 21

What are the six brain areas?

Answer 21

1) Motor Cortex
2) Auditory Cortex
3) Visual Cortex
4) Somatosensory Cortex
5) Brocas Area
6) Wernicke’s Area

Question 22

What was the one word patient Tan could say?

Answer 22

Tan

Question 23

What does plasticity refer to?

Answer 23

The brains ability to change and adapt both physically and functionally as a result of experience and new learning

Question 24

What is synaptic pruning

Answer 24

As we get older the connections that we barley use are deleted

Question 25

What did Maguire et al (2000) find out about taxi drivers

Answer 25

They had significantly more grey matter in their rear hippocampus than in the matched control group (a group of non-taxi drivers) This part of the brain is associated with the development of spatial and navigational skills.

Question 26

Does Lashley's (1950) Equipotentiality Theory aid localisation? Why?

Answer 26

No Lashley proposed the Equipotentiality theory, which suggests that the basic motor and sensory functions are localised, but that higher mental functions are not.

Question 27

What is Hemispheric Lateralisation

Answer 27

An idea that 2 halfs of the brain do different things

Question 28

What does the Corpus Callosum do?

Answer 28

Connects the left and right Hemisphere

Question 29

What are the 3 Types of biological rhythms

Answer 29

Circidian - Less than 24H Infardian - Longer than 24H Ultraradian - Takes less than 24H

Question 30

Biological Rhythms are regulated by endogenouspacemakers and exogenous zeitgebers, what do both of these do?

Answer 30

EZ- External Cues EP- The bodys internal biological clocks

Question 31

How long do Circadian Rhythms Ultradian Rhythms Infradian Rhythms Take?

Answer 31

Circadian: 24 Hours (C is for clock) Ultradian: less than 24 hours (U is for under 24 hours) Infradian: Longer than 24 Hours (I is for Infinity)

Question 32

What are Endogenous Pacemakers?

Answer 32

Internal mechanisms that govern biological rhythms

Question 33

Give 3 ways of studying the brain

Answer 33

fMRI's EEG's ERP's

Question 34

What was the IV and DV in Sperry’s Split Brain Experiment?

Answer 34

IV- Whether or not the participant was ‘Splitbrain’ DV- How well they preformed on tasks

Question 35

Name one task Sperry gave to the ‘Splitbrains’ + What was the results of this task

Answer 35

Presenting a stimulus to the splitbrain patient so they couldn’t see the stimulus then asking to name it + If the stimulus was in the participants left hand they couldn’t name the stimulus due to senses of touch and language are dealt with by different hemispheres

Question 36

Give the results of Sperry’s Splitbrain research

Answer 36

Participants had been given an image in one half of their visual field then presented the same image in the other half, they responded like they hadn’t seen that image before

Answer 37

An individual who has undergone disconnection of their brains 2 hemispheres
