Introduction To Macro-neuroanatomy

Question 1

What is the daily energy allowance of our brain

Answer 1

20-30%

Question 2

Advantages to having if a brain are:

Answer 2

1. Make and use tools
2. Solve old and new problems
3. Use language and symbols to communicate
4. Abstract thought and logic
5. Highly complex social groups
6. Capacity to remember past and apply to future

Question 3

EQ stands for?

Answer 3

Encephalization

Question 4

What is encephalization?

Answer 4

Species brain mass divided by species body mass = size of brain relative to body mass, can compare across species

Question 5

Cerebral cortex does?

Answer 5

Higher order abilities I.e thinking and language

Question 6

Sub-cortical structures:

Answer 6

Emotional and motivational responses

Question 7

Psychosurgery example

Answer 7

Ablation

Question 8

Ablation:

Answer 8

Surgical removal or inserting electrodes into particular areas of brain to examine how it effects behaviour

Question 9

Neuroimaging:

Answer 9

Measuring Neural activity in the brain

Question 10

Examples of neuroimaging

Answer 10

1. Electroencephalography (EEG) 2. magnetic resonance imaging (MRI)
2. Functional magnetic resonance imaging (FMRI)
3. Position emission tomography (PET)
4. Brain stimulation (TMS and DBS)

Question 11

MRI:

Answer 11

Magnetic resonance imaging

Measure different types of tissue in brain

High spatial recognition

Detects white and grey matter

Question 12

EEG:

Answer 12

Electroencephalography

Records electrodes that are placed at certain locations

Measure brain activity

Can see brain responses quickly

Poor spatial recognition

Question 13

FMRI:

Answer 13

Functional magnetic resonance imaging

Measures oxygenated blood versus deoxygenated blood

More oxygen = more activity in regions

Poor resolution and delay in info

Question 14

PET

Answer 14

Position emission tomography

Invasive neuroimaging
