Question 1

Answer 1

1) A (Thalamus 2-Glass sections; slide 6)
2) B (Thalamus 2-Glass sections; slide 13)

Question 2

Answer 2

Blue – Lateral ventricle (Thalamus 2-Glass sections; slide 6)

Orange – Interventricular foramen (of Monroe) (Thalamus 2-Glass sections; slide 6)

Yellow – 3rd ventricle (Thalamus 2-Glass sections; slide 6)

Question 3

Answer 3

1) Red – Anterior nucleus
1) It receives most afferent from: mammillary nucleus of hypothalamus (via mammillothalamic tract) and cingulate gyrus (Thalamus lecture; slide 26)
2) In what system does it mainly function: limbic system (Thalamus lecture; slide 20 and 26)
2) Green – this is the ventral anterior nucleus and it is involved in the motor planning and control relay (Thalamus lecture; slide 20 and 28)
3) Olive – known as both the dorsomedial (DM) or medialdorsal (MD) (Thalamus lecture - slide 13; Thalamus 2-Glass sections – slide 7)
1) With what brain lobe is it primarily associated: prefrontal cortex (Thalamus lecture; slide 22 and 23)

Question 4

Answer 4

1) Yellow – Reticular nucleus (Thalamus 2-Glass sections; slide 10)
1) Type of nucleus: ‘gatekeeper’ (Thalamus lecture – slide 20 and 34; Thalamus 2-Glass sections – slide 10)
2) Inputs and outputs from the cortex and dorsomedial nucleus and inputs from thalamocortical and corticothalamic collaterals (Thalamus lecture – slide 34)

Question 5

Answer 5

1) Blue – Pulvinar (Thalamus 2-Glass sections – slide 16)
2) Orange – Centromedian nucleus (Thalamus 2-Glass sections – slide 13)
3) Yellow – Red nucleus (Thalamus 2-Glass sections – slide 13)
4) Green – Mamillary body (Thalamus 2-Glass sections – slide 13)

Question 6

Answer 6

1) Ventral posterior medial nucleus (VPM) (Thalamus 2-Glass sections – slide 14)
1) Inputs from somatosensory cortex for face and anterior insula (taste) as well as the conscious trigeminothalamic and gustatory pathways (Thalamus lecture – slide 31)
2) Ventral posterior lateral nucleus (VPL) (Thalamus 2-Glass sections – slide 15)
1) Inputs from somatosensory cortex for limbs and trunk and also from the conscious somatosensory trunk and limbs (Thalamus lecture – slide 30)

Question 7

Answer 7

1) Orange – head of the caudate nucleus; Aqua – Superior colliculus (Reference this image from Netters: https://www.netterimages.com/thalamic-anatomy-labeled-felten-1e-neuroscience-frank-h-netter-8287.html)
2) Lemon grass – Pulvinar (reference image in link above)
1) Functions in the visual integration, interpretation and response (Thalamus lecture – slide 25)
3) Blue – this is the inferior colliculus and it projects to the medial geniculate nucleus (via the brachium) (Thalamus lecture – slide 33)
