Question 19

all thalamic nuclei (except reticular) consist of

Answer 19

projection neurons

interneurons

Question 20

projection neurons

Answer 20

provide output from thalamus

Question 21

interneurons

Answer 21

inhibitory projections

Question 22

2 types of thalamic input

Answer 22

specific

regulatory

Question 23

convey thalamic nuclei info directly to cortex

Answer 23

specific input

Question 24

regulatory input

Answer 24

thalamic nucleus contributes to it before it is passed to cortex

Question 25

only thalamic nucleus that does not project to cortex

Answer 25

reticular nucleus

Question 26

reticular nucleus

Answer 26

important source of regulatory thalamic inputs | no projections to cortex

Question 27

reticular nucleus input

Answer 27

cortex and thalamus

Question 28

reticular nucleus output

Answer 28

inhibitory axons to thalamus

Question 29

how does reticular nucleus send collaterals to thalamus?

Answer 29

axons must traverse nucleus to enter/leave thalamus and send collaterals
