thalamus

Question 1

main function of the thalamus

Answer 1

filtering and processing different types of sensory information

Question 2

where is thalamus located:

A) Within the brainstem.
B) Adjacent to the cerebellum.
C) In the diencephalon.
D) Within the cerebral cortex.

Answer 2

C) In the diencephalon (base of the centre of the brain)

Question 3

what does the thalamus filters specifically and why?

Answer 3

filter things that can be done automatically without necessary getting through the cortex because the cortex gets overwhelmed and overloaded so easily

Question 4

does all sensory information passes through the thalamus to reach the cortex? true or false

Answer 4

true

Question 5

does all sensory information passes through the frontal cortex to reach the cortex? true or false

Answer 5

false

Question 6

is the thalamus a unique structure? true or false

Answer 6

false.

thalamus is composed go many different nuclei

Question 7

what is the thalamus important for?

A) Visual information and spatial awareness.
B) Attention and executive functions.
C) Movements and muscle tone.
D) Sensory gating and sleep.

Answer 7

D) Sensory gating and sleep.

Question 8

which nuclei require sensory gating?

A) Anterior nuclei
B) Pulvinar nuclei
C) Lateral geniculate nuclei
D) Mediodorsal nuclei

Answer 8

B) Pulvinar nuclei

Question 9

what improves sensory gating?

A) Nicotine
B) Dopamine
C) Serotonin
D) Glutamate

Answer 9

A) Nicotine

Question 10

which nuclei are necessary for sleeping?
A) Anterior nuclei
B) Pulvinar nuclei
C) Lateral geniculate nuclei
D) Mediodorsal nuclei

Answer 10

A) Anterior nuclei
D) Mediodorsal nuclei

Question 11

relate cortical region with their function when we perceive information incoming from the thalamus:

A) frontal a) processes visual info
B) parietal b) recognise nature of stimuli
C) temporal c) decides appropriate response
D) occipital d) recognise where it comes from

Answer 11

4. frontal - decides what to do
5. parietal - recognise where the stimuli comes from
6. temporal - recognise the nature of the stimuli
7. occipital processes the visual information

Question 12

What structure of the brain is responsible for this ‘selective attention’?

A) Anterior nuclei of the thalamus
B) Mediodorsal nuclei of the thalamus
C) Pulvinar nucleus of the thalamus
D) Thalamus

Answer 12

C) Pulvinar nucleus of the thalamus
