Basal ganglia

Fox and Mohammad Ali and lack of a cure thereof. Afflicting the basal ganglia of the brain, its well-known symptoms include tremor and loss of motor control [1]. Since no cure exists, patients with PD rely primarily on symptom relief. Groiss et al. describe in great detail the purpose and effectiveness of DBS in relation…

processing and object recognition. The cerebellum underlies the temporal and occipital parts. The prefrontal cortex is involved in memory, language, and intelligence functions. The nucleus accumbens, on the other hand, is found the region called the basal forebrain and is important in the reward system in the addiction process (“Gray matter”, 2002). Cannabis affects all of these parts of the brain through…

Strong neural circuitry makes the DLPFC and PPC highly interconnected and communication between the two regions represents the executive level of the sensorimotor hierarchy. John’s cortex relays the movement goal with the subcortical nuclei of the basal ganglia to strategically gate muscle activity via selective initiation/inhibition. Next, the premotor cortex and supplementary motor area coordinate with the cerebellum to specify the precise sequence of contractions of the various muscles that…

Tourette's syndrome is a problem with the nervous system that causes people to make sudden movements or sounds, called tics, that they can't control. For example, someone with Tourette's might blink or clear their throat over and over again. Some people may blurt out words they don't intend to say. Treatments can control tics, but some people don’t need any unless their symptoms really bother them. Your nervous system is involved in everything your body does, from regulating your breathing to…

Schizophrenia and motivation Literature review Ohio State University Francis Robinson Schizophrenia and Motivation Literature review Schizophrenia is a debilitating psychiatric disorder that is often defined by its signs and symptoms (Giusti-Rodriguez & Sullivan, 2013). It is a lifelong disorder that is often distinguished by its severity and identified by its remissions, symptoms, and functional impairments. Disorders range from schizophrenia to schizophrenia like personality…

“And she said 'We are all just prisoners here, of our own device’/And in the master 's chambers/They gathered for the feast/They stab it with their steely knives/But they just can 't kill the beast,” states the song “Hotel California.” The Eagles had a special meaning in mind while writing that song. The topic was addiction, and this paper will touch on the same topic; however, there will be a slight twist. The twist being this question: Is a habit an addiction? This question has been asked…

Sleeping is a natural part of our daily life. It is a behavior that is displayed every day and is necessary for us to function. To be able to rest efficiently an animal, be it a human or another mammal, needs to fall asleep in a matter of seconds or minutes; but since a sleeping animals are more vulnerable to predation, it also needs to wake easily in case of threat. Those requirements show how well regulated the sleep-wake regulation has to be. Historically, sleep studies have been done by a…

one’s eyes shift their focus from one object to another. The FEF produces saccade movement through four major pathways, “(1) a projection to the ipsilateral superior colliculus concentrated in the intermediate layers, (2) a pathway through the basal ganglia via the ipsilateral striatum, (3) a projection to the cerebellum via the pontine nuclei, and (4) a weaker projection to mesencephalic and pontine nuclei that make up the saccade generator circuit” (Schall…

contains the hypothalamus and thalamus. Which that maintains functions like controlling everyday functioning, relaying information, motor control. The telencephalon maintains the functions such as the cerebral cortex, amygdala, the hippocampus,basal ganglia,and the olfactory…

brain activity of someone without the disease. The most significant clinical sign in diagnosing someone with Parkinson’s is bradykinesia. Bradykinesia is the abnormal function of the basal ganglia-cortical neuronal circuits, which then results in a disorder of the motor functions (7). The neurons in the basal ganglia output structures are being disturbed resulting in increased bursting, firing, correlated activity, an augmented synchrony, and a tendency towards loss of specificity in their…
