Myoclonus Information Page Myoclonus can also occur due to specific diseases affecting the nervous system, such as Parkinson’s disease, dementia, epilepsy, structural abnormalities in the spinal cord, or a lack of oxygen to the brain. In some diseases, myoclonus is a primary symptom, such as in myoclonus-dystonia.

Neuroscience For Kids The Primary Somatosensory Cortex. Parts of the cerebral cortex in the parietal lobe are involved with processing information related to touch. One such area is the primary somatosensory cortex which is located behind the central sulcus.Neurons in the primary somatosensory are activated when the skin is touched.However, the body is NOT represented in the cortex in proportion to the amount of skin. A map of the human somatosensory cortex was drawn by Dr. Wilder Penfield, a neurosurgeon, in the 1950s.eurons in the primary somatosensory are activated when the skin is touched.

- The somatosensory cortex integrates sensory information from the body, producing a map similar to that of the primary motor cortex. Transcript: The somatosensory cortex (postcentral gyrus) receives tactile information from the body.Sensory information is carried to the brain by neural pathways to the spinal cord, brainstem, and thalamus, which project to the somatosensory cortex (which in turns has numerous connections with other brain areas).t integrates sensory information (e.g. touch, pressure, temperature, and pain, spatial attention), producing a 'homunculus map', similar to that of the primary motor cortex. Sensory information about the feet, for example, map to the medial somatosensory cortex.

Progressive Supranuclear Palsy (Symptoms, Stages, Treatment, and Life Expectancy) What is progressive supranuclear palsy? Progressive supranuclear palsy (PSP) is an uncommon brain disorder that affects movement, control of walking (gait) and balance, speech, swallowing, vision, mood and behavior, and thinking. The disease results from damage to nerve cells in the brain. The disorder’s long name indicates that the disease worsens (progressive) and causes weakness (palsy) by damaging certain parts of the brain above nerve cell clusters called nuclei (supranuclear). These nuclei particularly control eye movements.

What Are Frontotemporal Disorders? Damage to the brain’s frontal and temporal lobes causes forms of dementia called frontotemporal disorders. Frontotemporal disorders are the result of damage to neurons (nerve cells) in parts of the brain called the frontal and temporal lobes.As neurons die in the frontal and temporal regions, these lobes atrophy, or shrink.hanges in the Brain. Frontotemporal disorders affect the frontal and temporal lobes of the brain. They can begin in the frontal lobe, the temporal lobe, or both. Initially, frontotemporal disorders leave other brain regions untouched, including those that control short-term memory.

What Is the Primary Somatosensory Cortex? The primary somatosensory cortex is a region of the brain where nerve signals from the sense of touch are normally received. It is generally located in a part of the brain called the parietal lobe, in a structure called the post central gyrus.f this area is damaged, a person can touch something, feel it, but not be able to figure out what it is. Scientists first mapped the primary somatosensory cortex in the 1950s. During brain surgery, surgeons could stimulate parts of the brain and see where a patient felt something.

- From Wikipedia, the free encyclopedia. Basal ganglia disease refers to a group of physical dysfunctions that occur when the group of nuclei in the brain known as the basal ganglia fail to properly suppress unwanted movements or to properly prime upper motor neuron circuits to initiate motor function.long with other structures, the basal ganglia are part of a circuit that is integral to voluntary motor function. It was once believed that the primary function of the basal ganglia was to integrate projections from the cerebral cortex, and project information via the thalamus to the motor cortex.

The somatically preoccupied patient in primary care: use of attachment theory to strengthen physician-patient relationships Somatic preoccupation is similar to somatoform disorders in that the patient has somatic symptoms which occur despite there being no causal disease or clinical finding [ 1 ]. Estimates of the prevalence of somatoform disorders in primary care range from 14% to as high as 26% [ 2 - 4 ]. Somatic Preoccupation and the Physician-Patient Relationship: This section introduces how working with somatically preoccupied patients presents unique risks for physicians in terms of establishing and maintaining a good physician-patient relationship.

Somatosensory system The somatosensory system is spread through all major parts of a mammal 's body (and other vertebrates). It consists both of sensory receptors and sensory (afferent) neurons in the periphery (skin, muscle and organs for example), to deeper neurons within the central nervous system.rocessing primarily occurs in the primary somatosensory area in the parietal lobe of the cerebral cortex: information is sent from the receptors via sensory nerves, through tracts in the spinal cord and finally into the brain.

Test Bank Of Essentials of Anatomy And Physiology 7th Edition by Martini Bartholomew Once in the thalamus, the secondary afferents synapse in a thalamic nucleus called the ventrolateral posterior nucleus (VPL). The thalamocortical afferents (from thalamus to cortex) travel up through the internal capsule to get to primary somatosensory cortex, the end of the pathway. Primary somatosensory cortex is located in the post-central gyrus, which is the fold of cortex just posterior to the central sulcus.

Von Recklinghausenâs Disease (Neurofibromatosis 1) Von Recklinghausen’s disease (VR) is a genetic disorder characterized by the growth of tumors on the nerves. The disease can also affect the skin and cause bones deformities.There are three forms of VR: neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis, considered a variant of type 2.ymptoms of Von Recklinghausen’s Disease. VR affects the skin and the peripheral nervous system. The first symptoms are usually observed in childhood and affect the skin.

- Lesson Summary. The somatosensory cortex is an important part of the cerebral cortex in the brain that processes sensory information from the body. Neurons from different parts of the body that receive environmental stimuli all send their information to the somatosensory cortex.cientists have mapped out which part of the somatosensory cortex processes information from which part of the body. This map is called the homunculus and is important to understanding how sensory information is processed. To unlock this lesson you must be a Study.com Member.

Posterior cortical atrophy Posterior cortical atrophy (PCA), also called Benson's syndrome, is a form of dementia which is usually considered an atypical variant of Alzheimer's disease.he main symptom resulting from PCA is a decrease in visuospatial and visuoperceptual capabilities. Because the posterior region of the brain is home to the occipital lobe, which is responsible for visual processing, visual functions are impaired in PCA patients.
