1

What is the daily energy allowance of our brain

20-30%

2

Advantages to having if a brain are:

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

3

EQ stands for?

Encephalization

4

What is encephalization?

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

5

Cerebral cortex does?

Higher order abilities I.e thinking and language

6

Sub-cortical structures:

Emotional and motivational responses

7

Psychosurgery example

Ablation

8

Ablation:

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

9

Neuroimaging:

Measuring Neural activity in the brain

10

Examples of neuroimaging

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

11

MRI:

Magnetic resonance imaging

Measure different types of tissue in brain

High spatial recognition

Detects white and grey matter

12

EEG:

Electroencephalography

Records electrodes that are placed at certain locations

Measure brain activity

Can see brain responses quickly

Poor spatial recognition

13

FMRI:

Functional magnetic resonance imaging

Measures oxygenated blood versus deoxygenated blood

More oxygen = more activity in regions

Poor resolution and delay in info

14

PET

Position emission tomography

Invasive neuroimaging
