Cerebral cortex

In a study it was discovered a structural difference in two parts of brain, in the cerebral cortex and thalamus. The cerebral cortex it is a six layer in the outer part of the brain which processes sensory, motor, memory, language, and attention. The thalamus is located in the center of the brain it processes information from the eyes and ears (Neuroscience

2014). To obtain a better understanding of this theory, the history of this theory will be explored. In 1825, the localization of mental processes was introduced by Franz Joseph Gall. Gall proposed that the brain contained distinct organs within its cortex, each of which served a specific moral, spiritual, or intellectual ability. Localization was mostly a discredited concept until Paul Broca’s critical supporting contribution

The fundamental ability of the prefrontal cortex is to represent information not currently in the environment; its role within the temporal lobe is to create a mental sketch pad within an individuals mind (Goldman-Rakic). It regulates short term and long term decision making and helps individuals focus thoughts and houses active working memory. Due to the funtions that the prefront cortex displays, damage to this area commonly leads to multiple problems such as the inability to plan or even behaving

questions. 2. List the five subcortical structures of the forebrain. Then, briefly explain the function of each structure. The Thalamus receives most of the incoming sensory information (excluding smells) and then relays that information to the cortex. The Hypothalamus receives input form the body and the brain and then sends its influence to the out to the entire body, affecting and regulating things such as body functions, body rhythms, and behavior motivations. The Hippocampus helps us in forming

Hypoglycemia describes an abnormally low level of sugar (glucose) in the blood. Hypoglycemia is not a disease in itself, rather it is a sign of a health problem. The aspect of this study is as followed: Hypoglycemia has been a common clinical condition known to affect human development. Little has been done to define the resultant brain biochemical alterations. A controlled study of hypoglycemia in the newborn human infant is impossible, the infant rat was chosen as a model. During this experiment

Histological /Anatomic levels In a macroscopic view of the nervous system, we can distinguish two morphological entities within its different parts, a first, grey (called grey matter), hosts mostly the somas, which qualifies it to play a role of processing centers, while the other is white (White matter) where we can find the axons of the somas covered by a myelin sheath (enhancing the membrane’s capacitance) who plays mostly the role of cables. Anatomically speaking, the nervous system is divided

I) Describe what would happen if there was a thrombosis (clot) in the middle cerebral artery? Anterior cerebral artery? Basilar artery? MCA: hemiparesis or hemiplegia of lower half of the contralateral face, Hemiparesis/hemiplegia of the contralateral upper and lower extremities, sensory loss of contralateral face arm and leg, ataxia and contralateral extremities, speech impairments or aphasia usually from a left brain lesion; perceptual deficits, visual disorders -ACA: hemiparesis or hemiplegia

Over the years, brain-computer interfaces (BCIs), or brain-machine interfaces (BMIs), have advanced into a technology that can be regularly be applied to the medical field. BCIs have been used for rehabilitative purposes, such as patients suffering from loss of speech and motor functions. Every year, approximately 795,000 people suffer a stroke. Out of these people, 600,000 of these are first attacks and 185,000 are recurrent attacks [9]. Stroke patients often suffer from paralysis and loss of speech

Alzheimer’s disease is a progressive mental deterioration that can happen in middle or old age, due to generalized degeneration of the brain. Alzheimer’s disease is one form of dementia that gets harmful over time. Dementia is a loss of brain function that occurs with other diseases such as Alzheimer’s. Scientists believe that Alzheimer’s disease results from genetics, lifestyle, and environmental factors that impact the brain. Alzheimer’s disease damages and kills brain cells and it also leads

During these seizures, high-voltage, synchronous discharges occur over the entire cortex. Furthermore, the same type of discharge occurs on both sides of the brain at the same time, showing that the abnormal neuronal circuitry responsible for the attack strongly involves the basal regions of the brain that drive the cortex. In humans, grand mal attacks can be initiated by administering neuronal stimulants, such as the drug Metrazol, or they can be caused
