Cerebral aneurysm

and internal organs. The largest part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which develop from the forebrain. The hemispheres have the cerebral cortex which contains ten billion nerve cells. Underneath is the brainstem, and behind that is where the cerebellum is. The outermost layer of the cerebrum is the cerebral cortex is divided…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

Evidence that Neurological Mirroring Extends to Humans: While the findings on specific mirror neuron system functioning is remarkable, it must be noted that the initial breakthrough single cell recording studies were not done with human participants, but with monkeys. Therefore, the systems and the presence of mirror neurons in humans can be deduced but not directly tested due to the ethical concerns of the single mirror neuron recording methods. As a result, skeptics have emerged with…

One of the many diseases caused by faulty cell-to-cell communication is Alzheimer’s disease. This disease causes many cells in the brain to die. Therefore, as more and more of the cells die, it causes the brain to shrink. What causes the brain cells to die, which then causes the brain to contract, is the unusual twist of the protein called tau. Tau is a protein in the brain that delivers nutrients and other important elements to the brain cells. The effect of the twisted protein inhibits the…

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,…

The cerebral cortex is formed up of overlapped and intertwined gray matter in the cerebrum of the brain. It is associated with the superior brain functions, coordination of sensory information, the capability to gain knowledge, the consciousness of being able to receive memory, along with the expression of originality, therefore playing an essential part in our consciousness. The cerebral cortex consists of very small layers of cells composed of billions of neurons as well as their endless…

termed memories. As MDhealth.com informs us, “The hippocampus also helps people analyze and remember spatial relationships, allowing for accurate movements.” This part of the brain can be found in the middle of the bottom of the temporal lobe in the cerebral hemisphere. If this part of the brain were to be damaged, you would just forget everything eventually and you could only live in the present. The next part of the limbic system is the amygdala; this part of the limbic system controls your…
