Multiple Sclerosis My symptoms started off with extreme muscle spasms and cramps. It would get worse when I was on my monthly. I was walking and running at the time to lose some weight that I thought was causing the muscle aches, headaches, and the pain that I was feeling in my whole body. One day it got overwhelming.

In 1995, Swanson, L. and his team conducted an experiment, hoping to confirm that phantom limb pain was in fact coming from the two previously mentions sources; neuromas and abnormal discharges in the spinal cord. In their experiment, they used anaesthetics to inhibit the brachial plexus and spinal anaesthesia to reduce pain from the spinal cord in already amputated rats. However, it was reported that 17% of the rats continued to show discomfort, suggesting yet another source for phantom limb pain

According to ADDitude, the way the game works is the player where's a headset and the character/vehicle in the game is controlled by one's brain waves. For example, in a car race the car slows down when the player “exhibits low-frequency patterns…his car slows and other cars

drugs produce may beneficial effects. While some studies suggest smart drugs to be effective, others have shown it to be ineffective and also poses adverse effects. Smart drugs will not work for everyone because the brain is a complex system also because the structure of everyone's brain varies. Smart drugs are fictional because they help individuals focus and pay attention. Smart drugs are not only used to perform better in school and on standardized tests, they are helpful performing tasks at work

Stressful experiences manifested effects through the activation of several mechanisms that linked to the onset of a variety of affective disorders. Investigations on the interaction between stress and memory experiences focused mainly on behavioral and neurological mechanisms of memory conformation (such as conditional fear), and fewer studies on the fear memory extinction as a treatment for psychiatric conditions based on learned fears Such as phobias, PTSD, and general anxiety. Post-traumatic stress

The brain and spinal cord have the vital job of controlling every bodily function thus controlling every body system. Two systems which they interact with are the endocrine and respiratory system. Central Nervous System’s Interactions with the Endocrine System The endocrine system sends hormones into the blood, sending messages throughout the body. This role is much like the central nervous system’s, which sends messages throughout the body by neuron synapse. The hypothalamus is a tiny collection

warmth and give a signal to the interneurons in your spine. The interneurons then synapse to the motor neurons, which make sure your hand is pulled away. Only later comes the realization of the action. A reflex happens without giving a signal to the brain, whereas a determined action does give a signal to the

stabilization. There are a group of cells known as gangli that receives information from the cerebral cortex and sends that information to the striatum, which is the central part of the brain. The cerebral cortex and the gangli allows for smooth movement. The impulses involved are passed between neurons, moved from the brain to the spinal cord and eventually to the muscles. In Parkinsons Disease, the lack of dopamine in the body cause the body to react and begin firing other neurotransmitters such as Glutamate

Lissencephaly is a brain malformation, in which the brain does not fully develop the gyri or ridges that cover the surface of the brain. Lissencephaly can be caused by a genetic mutation of at least two different genes on chromosome seventeen and X-chromosome called doublecortin. It could also be caused by a viral infection. It is also most common in Miller-Dieker syndrome and Norman-Roberts syndrome (“Lissencephaly”,2012). Miller-Dieker is a condition where an individua has facial abnormalities
