putamen

 [pu-ta´men]
the larger, darker, and more lateral part of the lentiform nucleus, separated from the lateral globus pallidus by the lateral medullary lamina.

pu·ta·men

(pū-tā'men), [TA]
The outer, larger, and darker gray of the three portions into which the lenticular nucleus is divided by laminae of white fibers; it is connected with the caudate nucleus by bridging bands of gray substance that penetrate the internal capsule. Its histologic structure is similar to that of the caudate nucleus together with which it composes the striatum.
See also: striate body, lenticular nucleus.
[L. that which falls off in pruning, fr. puto, to prune]

putamen

/pu·ta·men/ (pu-ta´men) the larger and more lateral part of the lentiform nucleus.

putamen

(pyo͞o-tā′mən)
n. pl. pu·tamina (-tăm′ə-nə)
1. The hard endocarp of certain fruits; pyrene.
2. The reddish, outermost, and largest of the three portions into which the lentiform nucleus of the brain is divided.

putamen

[pyo̅o̅tā′mən]
Etymology: L, putamen, husk
a part of the lentiform nucleus that is lateral to the globus pallidus. It is associated with the corpus striatum and receives connections from the suppressor centers of the cortex.

The outer, larger, and darker gray of the three portions into which the lenticular nucleus is divided by laminae of white fibers; it is connected with the caudate nucleus by bridging bands of gray substance that penetrate the internal capsule. Its histologic structure is similar to that of the caudate nucleus; together they compose the striatum.

putamen

The outer shell of the lentiform nucleus of the BASAL GANGLIA of the brain.

basal ganglia

central nervous system ganglia (i.e. caudate nucleus and putamen [i.e. the striatum], lentiform nucleus and substantia nigra) that control and coordinate fine movement; their output inhibits movement (other than postural reflexes) when at rest, and assists movement initiation by inhibiting postural reflexes

putamen

the larger and more lateral part of the lenticular nucleus.

Neuroimaging studies have revealed that the dorsal striatum plays an important role in learning such stimulus-action-reward associations, with a functional difference between the putamen and the caudate nucleus.
Hence, the degree of Parkinsonism is associated with pathology in the striatum and especially the putamen and the substantia nigra.
In addition to imaging, short-TE single-voxel spectra (PRESS localization; TR/TE = 1,500 msec/30 msec; CHESS water suppression) were acquired from five different VOIs in each subject: frontal cortex (8 mL VOI, 96 averages), putamen (4 mL VOI, 128 averages), globus pallidus (4.
In this study, we aim to overcome this limitation and develop an algorithm capable of separating the striatum into four structures (caudate, putamen, ventral striatum, and white matter) [3].
Beyin MRG'sinde klinik bulgularla uyumlu olacak sekilde pons orta bolumunde, bilateral putamen lokalizasyonunda ve bilateral kaudat nukleuslarda lezyon alanlan izlendi.
A case report from 2003 of a patient with heat stroke revealed a bilateral external capsule, bilateral putamen, and a bilateral cerebellar process with probable blood products on T2- and T1-weighted images and some enhancement on gadolinium images.
Parkinson's disease is primarily associated with the loss of dopaminergic neurons Within the substantia nigra, allowing the caudate and putamen to become overly active and possibly cause continuous output of excitatory signals to the corticospinal motor control system (40).
Additionally, a relative increase in grey matter volume was observed bilaterally in the ventral part of the putamen and in the anterior cerebellum.
So, according to Montague, we have been brainwashed by years of advertising telling us that Coke is better, so that when we see a can and take a swig our ventral putamen thinks 'bingo'.
PUTAMEN AND BMI: THE RELATIONSHIP THROUGH THE MOTOR PATHWAY OF THE BRAIN.
Structures such as the caudate, putamen, and globus pallidus serve as inhibitors or modulators of behavior and have found to be abnormal.
The putamen is a region of the brain that undergoes degeneration and reduced dopamine production in Parkinson's disease patients, which has been closely linked to the major motor deficits in the patients.
