Basal ganglia

brain is to produce movements. Several different regions of motor cortex are involved in controlling the body's movements. The brain controls what you do over all. Sometime the half that is used is connected to which hand people use also. The basal ganglia consist of a set of neural structures buried deep inside the cerebrum. They also rescue or collect information from several different regions of…

Other evidence in support of the dopamine hypothesis relating to the substantia nigra include structural changes in the pars compacta. Some of the other changes in the substantia nigra include increased expression of NMDA receptors, and reduced dysbindin expression. Increased NMDA receptors may point to the involvement of glutamate-dopamine interactions in schizophrenia. Due to the changes to the substantia nigra in the schizophrenic brain, it may eventually be possible to use specific imaging…

and visual cortex using a functional MRI. The precuneus was active in both the amauter and professional players. Wan found that the caudate nucleus in basal ganglia, which is responsible for cognition and procedures, was significantly more active in the professionals. Shogi masters had more brain activity than others especially in the basal ganglia region of the…

the middle cranial fossa. The middle cerebral artery (MCA) is the region of interest as this is the most common site for ischemic strokes. The MCA consists of four sections. The M1 segment consists of lenticulostriate vessels which irrigate the basal ganglia. The M2 segment extends anteriorly on the insula, and the M3 segment expands laterally and exteriorly from the insula towards the cortex. Finally, the M4 segment supplies the cortex at the Sylvian fissure. The frontal, parietal, and temporal…

Fetal Alcohol Syndrome is a congenital syndrome. It is known to be caused by alcohol consumption by the mother during pregnancy. Intellectual and mental disabilities, stunt of growth, behavioral problems, learning disabilities and a lack of sense for cause and effect are just a few of the characteristics of Fetal Alcohol Syndrome. New research shows that the father's’ drinking habits prior to conception can also contribute to fetal abnormalities. Fetal Alcohol Syndrome is 100% preventable.…

disease was discovered and recognised as an inherited disease in 1872 by George Huntington, the discovery of the gene came later in 1993 when a group of scientist found it on the HTT gene. The disease causes degeneration of nerve cells in the basal ganglia in the brain and behavioral, cognitive, and movement problems for example, problems with mood, memory and speech. There are three main stages of Huntington's disease, early, mid, and late stages. In the early stage there are small noticeable…

Have you ever thought about where dreams come from? We have all been there in the middle of the night, where a dream seems so real that you wake up thinking you have actually experienced it. Some people think dreams happen because we are recalling events that occurred earlier in the day, or maybe because we are able to have visions from the future, but do we really know their main origin? Aristotle once defined dreams as a perceptionless state where our senses of our outside stimulus are shut…

2015; Satoh et al 2010). Regeneration can be saved by cDNA coding of the protein, nAG (Whited & Tabin 2009). This protein replaces a nerve. Skin wounds without a deviated nerve and wounds of denervated limbs reform a basal lamina within few days after injury. However, the basal lamina under the apical epidermal cap does not reform until the end of regeneration (Aguilar & Gardiner 2015). Humans Wounding occurs when the epidermal layer is breached. (Yeng 2011) Depending on the depth of the injury…

There has been recent research that has stated that obsession-compulsion disorder involves the dysfunction in a neuronal loop that runs from the orbital frontal cortex to the cingulate gyrus, striatum (cuadate nucleus and putamen), globus pallidus, thalamus and then back to the frontal cortex (Yerevanian, 2010). To back up The Carlat Psychiatry Report’s research, supporting the hypothesis is the results of neurosurgical treatment of obsession-compulsion disorder (Huey, 2010). Believed to…

Picture a sponge. A common household item that is very simple yet useful. Now compare that sponge to the human brain. It’s porousness allows outside substances to seep in and be collected. The sponge grows and holds more than expected of it. Much like the sponge, our brain can absorb and retain valuable resources. Without the brain, humans would not be able to function. The brain, a highly complex part of the human anatomy, is in charge of one’s intelligence, the senses, producer of all body…
