Where are the cortices?

In the frontal, temporal and parietal lobe

1

What do association cortices receive?

The input directly from other cortical areas. Insilateral and interhemispheric cortico-cortical connections. Also, highly processed info from primary sensory and motor areas via the thalamic nuclei and subcortical imputs.

2

Define attention?

The state of selectively processing simultaneous sources of information.

3

What does attention involve?

Preferential processing of sensory information eg. Visual and auditory

4

What does attention allow?

Covert shifting and increased reaction time to stimuli.

5

What is smaller in attention-deficient hyperactivity disorder?

Prefrontal cortex and basal ganglia

6

What is contralateral neglect syndrome?

Failure to attend to objects in a portion of space

7

What causes contralateral neglect syndrome?

Lesion in the right parietal cortex

8

What else is caused by a lesion to the parietal cortex?

Balints syndrome

9

What is emotional processing?

Composite of feelings, expressive behaviours and physiological changes.

10

What is the generation of emotion?

Evaluation, conscious of unconscious experience and expression

11

How many components does an emotional response consist of? Name them.

3, behavioural, autonomic and hormonal.

12

What are the brain systems involved in emotions in processing?

Limbic system, amygdala, orbitofrontal cortex, cingulate gyrus, thalamus and ventral basal ganglia

13

What is speech produced by?

Lungs, larynx, pharynx, oral cavity and nasal cavity

14

What is language?

Speech of a group of people or speech production and comprehension by the brain

15

Language is both ..... and ....?

Localised and lateralised

16

Give the areas of the brain involved in language?

Association cortices in the left hemispheres, the Broca's area (left frontal cortex) and the wernickes area (left temporal cortex)

17

What is aphasias?

Damage to specific brain regions which compromises language functions, without affecting sensory/motor processing.

18

Give the three types of aphasias and brief descriptions?

Broca's- motor or expressive
Wernickes- sensory or receptive
Conduction- difficulty repeating words

19

What parts of the brain are important for executive control systems?

Prefrontal cortex, dorsolateral prefrontal cortex, ventromedial prefrontal cortex, basal ganglia, anterior cingulate cortex and posterior parietal cortex.

20

What is the dorsolateral prefrontal cortex responsible for?

Initiating and shifting behaviour, inhibiting behaviour and simulating behavioural consequences.

21

What is the venrtomedial prefrontal cortex responsible for?

Inhibition of socially inappropriate behaviour and sensitivities to the co sequence of action
