|
One is to put an electrode in the brain to destroy the pea-sized area in the thalamus responsible for the shakes. |
|
The brain sends a message under an electric form to the thalamus, and the thalamus send a message under a chemical form in all the cells of our body. |
|
The brain sends an electrical pulse, an information which is transformed in chemistry by the thalamus and which goes through the body, all the cells, on a chemical way. |
|
Researchers are interested in the central nervous system processing of information, including pain, which is thought to occur in the spinal cord, thalamus and cortex. |
|
Other cerebral structures include the hypothalamus, which controls metabolism and maintains homeostasis, and the thalamus, a principal sensory relay centre. |
|
The dorsal column-medial lemniscus system has classically been viewed as a pathway involved in conveying somatic epicritic tactile and kinesthetic sensory information to the thalamus. |
|
The thalamus receives blood from both the anterior and posterior systems to varying degrees. |
|
Four of the tumors were located in superficial cerebrocortical locations and 1 case arose in the thalamus. |
|
|
Stereotactic Thalamotomy, surgery of the brain in which a lesion is made in the thalamus to block the electric impulses that cause tremor. |
|
The inferior colliculus receives both crossed and uncrossed auditory fibres and projects upon the medial geniculate body, the auditory relay nucleus of the thalamus. |
|
The hypothalamus is located at the base of the forebrain beneath the thalamus and posterior to the optic chiasma. |
|
The spongiform changes are most evident in basal ganglia and thalamus. |
|
This condition is a result of absent subthalamic nucleus inhibition, which increases motor activity through the motor thalamus. |
|
Although a number of medications are effective in reducing the movements, surgical destruction of the ventrolateral nucleus of the thalamus may be performed to relieve muscle rigidity in severe cases. |
|
The cerebellum continuously receives input from the trunk, limbs, eyes, ears, and vestibular apparatus, maintaining in turn a continuous transfer of information to the motor parts of the thalamus and to the cerebral cortex. |
|
It is at the hormonal level of the thalamus that it happens. |
|
The information was obviously being processed somewhere beyond the thalamus, but not in the auditory cortex, in order that the fear reaction occurred. |

In regard to lesioning, pallidotomy and thalamotomy involve making a permanent lesion in the Gpi and thalamus, respectively. |
|
During this measure of executive function, decreases were seen in the cuneus, middle temporal gyrus, inferior parietal lobule, insula, and medial dorsal nucleus of thalamus. |
|
Additionally, afferent mechanoreceptor impulses travel up the cord to the cerebellum and thalamus, affecting thalamic summation and integration and cortical representation. |

After those first neurons fire in response to a tickle, however, the signal travels to the brainstem and then on to another part of the brain, the thalamus. |
