Thalamus
2022-03-07: Neuroanatomy reference:
- How thalamic relays might orchestrate supervised deep training and symbolic computation in the brain
Thalamus #
(this structure shown is the Diencephalon)
- The sole relay between sensorimotor systems and the Cerebral Cortex, thus playing a key role in consciousness - small lesions lead to its loss. Surprisingly though, apparently conditions related to its damage are rare
R.
- Glutamatergic projections to the cerebral cortex.
- The cerebral cortex also gives it feedback on the thalamic reticular nucleus, almost entirely in the form of inhibitory neurons that synapse onto relay cells.
- Mainly Gray Matter
