Definition of thalamus in English:

thalamus

nounPlural thalami ˈθaləməsˈθæləməs

Anatomy

Either of two masses of grey matter lying between the cerebral hemispheres on either side of the third ventricle, relaying sensory information and acting as a centre for pain perception.
Example sentencesExamples
- By contrast, reduced activation in the mesencephalic brainstem and the thalamus was noted to be exclusively associated with mental relaxation.
- Peripheral injury results in anatomic and physiologic changes within the dorsal horn, sensory thalamus and cerebral cortex.
- The sleep cycle is controlled by a complex system of neurones (messenger cells) in the brain stem, thalamus, hypothalamus, and basal forebrain.
- They note that there is evidence to suggest that a circuit involving the thalamus and frontal lobes functions abnormally in autism.
- However, after controlling for this overall increase in metabolism in the methamphetamine abusers, the investigators showed that metabolism was significantly reduced in two brain regions - the thalamus and striatum.

Derivatives

thalamic

adjective ˈθaləmɪkθəˈlamɪk

Anatomy

Computed tomography of the brain demonstrated an area of low attenuation in the left thalamic region.
Example sentencesExamples
- During sustained hypoxia, increased thalamic gating may decrease respiratory sensory projections to higher centers.
- When we are asleep, thalamic neurons prevent penetration of sensory information upward to the cortex.
- An extensive accumulation of axons connecting various thalamic nuclei to practically all cortical areas is seen in fan-like array and this, in three dimensions, reflects the profusion of the thalamic radiations.
- The authors conclude that thalamotomy and thalamic stimulation are effective treatments for patients with severe tremors.

Origin

Late 17th century (denoting the part of the brain at which a nerve originates): via Latin from Greek thalamos.

Rhymes

calamus, hypothalamus
