Basal ganglia disease The basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus. Along with other structures, the basal ganglia are part of a circuit that is integral to voluntary motor function.

Basal ganglia Learn about this topic in these articles: structure of the brain. ...within the cerebral hemispheres, large gray masses of nerve cells, called nuclei, form components of the basal ganglia. Four basal ganglia can be distinguished: (1) the caudate nucleus, (2) the putamen, (3) the globus pallidus, and (4) the amygdala.

Basal ganglia The main components of the basal ganglia – as defined functionally – are the dorsal striatum (caudate nucleus and putamen), ventral striatum (nucleus accumbens and olfactory tubercle), globus pallidus, ventral pallidum, substantia nigra, and subthalamic nucleus.

- WASHINGTON, May 3, 2002- Venezuelan President Hugo Chavez survived last month's popular uprising, but democracy in that troubled country may not be so lucky unless the Bush administration takes an active role in promoting it, a new Heritage Foundation paper says.t can, for example, encourage international watchdog organizations to assess human rights, civil liberties, press freedoms and labor rights in Venezuela. It can press for much-needed reforms, from rooting out corruption to reducing state control of the economy.

Beta thalassemia Beta thalassemia is a blood disorder that reduces the production of hemoglobin. Hemoglobin is the iron-containing protein in red blood cells that carries oxygen to cells throughout the body.In people with beta thalassemia, low levels of hemoglobin lead to a lack of oxygen in many parts of the body.Affected individuals also have a shortage of red blood cells (anemia), which can cause pale skin, weakness, fatigue, and more serious complications.eta thalassemia is classified into two types depending on the severity of symptoms: thalassemia major (also known as Cooley's anemia) and thalassemia intermedia. Of the two types, thalassemia major is more severe. The signs and symptoms of thalassemia major appear within the first 2 years of life.

Insular cortex From Wikipedia, the free encyclopedia. In each hemisphere of the mammalian brain the insular cortex (often called insula, insulary cortex or insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes).he cerebral cortex processing vestibular sensations extends into the insula, with small lesions in the anterior insular cortex being able to cause loss of balance and vertigo. Other noninteroceptive perceptions include passive listening to music, laughter, and crying, empathy and compassion, and language.

Nucleus basalis magnocellularis The nucleus basalis magnocellularis (aka Nucleus Basalis of Meynert (' NBM)) is a nucleus in the basal ganglia. This is a group of cholinergic neurons in the substantia innominata of the basal forebrain which has wide projections to the neocortex and is rich in acetylcholine and choline acetyltransferase.n Parkinson and Alzheimer diseases the nucleus undergoes degeneration. A decrease in acetylcholine production is seen in Alzheimer's disease, Lewy body dementia and some Parkinson disease patients showing abnormal brain function, leading to a general decrease of mental capacity and learning.

- Plaques form when protein pieces called beta-amyloid (BAY-tuh AM-uh-loyd) clump together. Beta-amyloid comes from a larger protein found in the fatty membrane surrounding nerve cells. Beta-amyloid is chemically sticky and gradually builds up into plaques. The most damaging form of beta-amyloid may be groups of a few pieces rather than the plaques themselves. The small clumps may block cell-to-cell signaling at synapses. They may also activate immune system cells that trigger inflammation and devour disabled cells.

Basal ganglia The basal ganglia (or basal nuclei) comprise multiple subcortical nuclei, of varied origin, in the brains of vertebrates, which are situated at the base of the forebrain. Basal ganglia nuclei are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.

Basal ganglia nuclei are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.he largest component, the striatum (dorsal and ventral), receives input from many brain areas beyond the basal ganglia, but only sends output to other components of the basal ganglia. The pallidum receives input from the striatum, and sends inhibitory output to a number of motor-related areas.
