Cerebral hemisphere

the brain, as these levels are important and often become altered following a concussion. Functional magnetic resonance imaging (fMRI): is an anatomically based measurement that is able to detect the activity within the brain by measuring the cerebral blood flow. This type of imaging could be used in the assessment of a concussion because blood flow to the brain is essential given its high metabolic demand,…

an indirect pathway. The direct pathway facilitates a particular behavior while the indirect pathway suppresses the competing behavior. The hyper direct pathway connects the cerebral cortex and the Subthalamic nuclei which are responsible for termination of the behavior (6). The Striatum receives major input from the cerebral cortex and has an inhibitory effect on the Globus Pallidus(6). The STN provides glutamatergic input to G.P (Internal and external). The globus pallidus is the source of…

Neurodevelopmental disorders are disorders wherein impairments in neural development lead to deficits in various cognitive and/or social abilities (Reynolds & Goldstein, 1999). Historically, researchers have often assumed that human cognition is served by numerous “modules”, each of which performs a specific cognitive function. It is typically argued that each module is supported by a specific brain region whose evolutionarily-defined characteristics confer neural properties that facilitate…

significantly differ from non-sports related concussions (Gavett et al., 2011). CTE is considered a distinct disorder after numerous neuropathological studies of athletes with a history of repeated mild head injuries produced consistent findings of cerebral atrophy,…

Write an essay describing the neuron function. The nervous system is made of the central nervous system which includes: - The brain - Spinal cord It is also made up of the peripheral nervous system which is consisted of the sensory and motor neurons and lastly the autonomic nervous system which helps in modifying the body processes such as the digestion and heart rate for the body to function properly. [1] Neurons are excitable cells that help in processing and transmitting information. Even…

These are the normal contributions to everyday life. Amazing is the word that describes this small complex organ that cannot be mastered. Signals for body parts are forwarded from different parts of the brain, which are called the left and right hemispheres. Broca’s area is on the frontal left lobe known for transforming words from thoughts. There are four types of lobes designed to send and receive messages. There are names for frontal lobes, parietal lobes, occipital lobes, and temporal…

Multisensory integration is not an innate capability of the superior colliculi neurons, and is something that develops gradually as the organism matures. Because a large majority of the neurons in the superior colliculus are visually responsive, Wallace et al.1 hypothesized that visual stimuli was necessary for the development of multisensory integration. To test this claim, he and his colleagues reared 9 cats in complete darkness and tested each neuron in the superior colliculus for responses…

Primarily, Cerebral Palsy was called “Little disease” because the first medical description of this disorder was written by an English surgeon, William John Little (1810-1894) in late 1830s. Little described it as a brain injury, caused by asphyxia (Oxygen deficiency). He approached that this incidence happened during complicated processes of delivery that suffocated the child, and the child couldn’t get enough oxygen. The lack of oxygen damage the nervous system of the brain and cause spastic…

at the top of the spinal cord. The brain has three main parts, the cerebellum, and the cerebrum which has two parts, the left and right hemispheres and the brain stem. The corpus callosum is a thick band of nerve fibres that divides the cerebrum into left and right hemispheres, the left controls the right side of body responsible for language the right hemisphere controls the left side of body, responsible for spatial skills. It connects and communicates between the left and right sides of the…

There are many studies which suggest that cortical connection mostly occurs through feedback connections. However, feedback connections are not clearly understood. In these research papers, the experimenters focus on the role of feedback in the visual cortex. Although research has been done on this topic, it is difficult to study cortical feedback signals. I will use research by researchers Nassi, Lomber & Born (2013) for the first article. For the second article I will use the work of Bastos,…
