25
Where is the hindbrain located?
At the base of the brain
26
What is the hindbrain responsible for?
It controls and influences motor functions and vital automatic responses
27
What is the hindbrain made up of?
- The cerebellum - The medulla - The pons
28
What is the function of the cerebellum?
It coordinates fine muscle movements, posture and balance
29
What is the function of the medulla?
Control vital survival functions
30
What is the function of the pons?
Regulate sleep, arousal and breathiing
31
What is the deep furrow that divides the brain into 2 halves called?
The Corpus Callosum
32
What is the corpus callosum?
A bundle of axons which connects the 2 halves of the brain
33
What is the function of the corpus callosum?
Enable communication between the 2 hemispheres
34
Where is the corpus callosum located?
In the white matter of the cerebrum
35
What happens if the corpus callosum gets damaged?
Disables communication between the left hemisphere and right hemisphere
36
What is the cerebral cortex?
The outer layer of the brain
37
How thick is the cerebral cortex?
Between 1-4mm thick
38
How much of the cerebral cortex is visible from outside the brain?
Only 1/3
39
What does the cerebral cortex look like?
A highly-wrinkled structure
40
Why is the brain a highly wrinkled structure?
Makes the brain more efficient + increases the surface area of the brain & the neurons within it
41
What does the cerebral cortex consist of?
4 lobes
42
What are the names of the lobes that make up the cerebral cortex?
- Frontal lobe - Parietal lobe - Occipital lobe - Temporal lobe
43
What is a characteristic of the frontal lobe?
Largest of the 4 cortical lobes
44
Where is the frontal lobe located?
At the front of the brain
45
What are some key functions of the frontal lobe?
- Control high order thinking - Motor coordination - Expression + regulation of emotions - Personality
46
What does the frontal lobe do?
It integrates messages from all over the brain and coordinates appropriate responses
47
What can go wrong with the frontal lobe?
Diseases and disorders can be acquired or developed naturally
48
What happens if damage occurs to the frontal lobe?
Impairs the function
49
What is the primary motor cortex in the frontal lobe?
Strip of neutral tissue at the back of the frontal lobe
50
What does the primary motor cortex do?
Controls voluntary bodily movement through its control of skeletal muscles
51
What does the space devoted to the body structure correspond to (primary motor cortex)?
The complexity of the movements associated with it
52
Where is the Broca's area located?
In the left frontal lobe next to the motor cortex for the lips, mouth and tongue
53
What is the function of the Broca's area?
Enable articulate and fluent speech production
54
What happens when damage occurs to the Broca's area?
Impacts production of speech
55
What is the term associated with damage to the Broca's area?
Broca's aphasia
56
Where is the temporal lobe located?
In the lower central part of the brain, near the ears
57
What is the temporal lobe primarily involved in?
Auditory perception
58
What are some roles of the temporal lobes?
- Memory - Aspects of visual perception - Decision making - Object identification - Facial recognition
59
How does the temporal lobe have an important role in our decision making?
Helps us perceive + remember certain features of an environment
60
What are some examples of how the temporal lobe has a huge role in long-term memory formation?
- Factual information - 'How to' information - Personal experiences
61
What can go wrong with the temporal lobe?
- Disturbance of auditory sensation + perception - Memory impairment - Disturbance of language comprehension
62
What does the primary auditory cortex do?
Receive + process sound from both ears
63
What does the left auditory cortex specialise in?
Verbal sounds (voice, words etc)
64
What does the right auditory cortex specialise in?
Non-verbal sounds (music)
65
Whats term does the term "Word Salad" refer to?
Wernicke's Aphasia
66
How does Wernicke's Aphasia impact a patient?
- Great difficulty comprehending speech - Difficulty speaking in a meaningful way - Fluent + grammatically correct speech
67
Where is the occipital lobe located?
At the rearmost part of the cerebral cortex (back of the head)
68
What is a key function of the occipital lobe?
Processing and interpreting visual sensory information
69
What can go wrong with the occipital lobe?
- Blindness - Severity + location of the damage determines the long and short term outcomes - Impairment to the perception of colour, shape, size and distance
70
What is the primary visual cortex?
The final destination of visual information received from both eyes
71
What occurs in the primary visual cortex?
- Raw visual information is organised and processed - Neurons are specialised and respond to specific information
72
Where is the parietal lobe located?
Behind the frontal lobe
73
What does the parietal lobe occupy?
The upper back half of the brain
74
What are the key functions of the parietal lobe?
- Receive + process sensory information from the body and skin cells (somatosensory information) - Spatial awareness + attention
75
What can go wrong with the parietal lobe?
- Deficit function in lack of sensitivity - Tactile agnosia (inability to interpret sensation)
76
What does tactile agnosia do?
Deficiency in recognising objects
77
Where is the somatosensory cortex located?
In front of the parietal lobe behind the primary motor cortex
78
What does the somatosensory cortex do?
- Receives + processes sensory information from the skin and body such as: - Touch - Temperature of the skin - Information about muscle movement
