| Pronunciation (US): |  | (GB): | |
Irregular inflected form: thalami
I. (noun)
Sense 1
Meaning:
Large egg-shaped structures of grey matter that form the dorsal subdivision of the diencephalon
Classified under:
Hypernyms ("thalamus" is a kind of...):
neural structure (a structure that is part of the nervous system)
Meronyms (parts of "thalamus"):
geniculate body (one of four small oval masses that protrude slightly from the underside of the thalamus and function as synaptic centers on the way to the cerebral cortex)
subthalamus (the ventral part of the thalamus)
Holonyms ("thalamus" is a part of...):
betweenbrain; diencephalon; interbrain; thalmencephalon (the posterior division of the forebrain; connects the cerebral hemispheres with the mesencephalon)
Context examples:
An expansion of the subarachnoid space extending forward between the corpus callosum and the thalamus; it encloses the internal cerebral veins.
(Ambient Cistern, NCI Thesaurus)
A very rare congenital brain defect in which the cerebral cortex, striatum, globus pallidus, thalamus, hypothalamus, and eyes are absent or rudimentary.
(Aprosencephaly, NCI Thesaurus)
A large, cone-shaped area of gray matter within the basal ganglia comprised of the globus pallidus and putamen that is surrounded primarily by the caudate nucleus and the thalamus.
(Lenticular Nucleus, NCI Thesaurus)
The anterior and posterior paraventricular nuclei of the thalamus are included with the THALAMIC NUCLEI although they develop from the same pronuclear mass as the epithalamic nuclei and are sometimes considered part of the epithalamus.

They found beta-amyloid increases of about 5 percent after losing a night of sleep in brain regions including the thalamus and hippocampus, regions especially vulnerable to damage in the early stages of Alzheimer’s disease.

Although the exact mechanism of meprobamate is largely unknown, it appears to act as a depressant at multiple sites in the central nervous system, mostly likely through the GABAergic neurotransmitter system, including the thalamus and limbic system.

“In heavy drinkers, we saw less regional power for example in the thalamus, the sensory gateway, and frontal cortex of the brain, which is important for decision making,” said Dr. Shokri-Kojori of the NIAAA Laboratory of Neuroimaging.

Within these studies, MRI scans measured each participant's overall brain volume plus the volume of seven brain regions thought to be linked to ADHD: the pallidum, thalamus, caudate nucleus, putamen, nucleus accumbens, amygdala and hippocampus.
