this technique‚ real life examples and concluding it with its advantages over the prevailing one. Introduction A Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer.The 100 billion neurons communicate via minute electrochemical impulses‚ shifting patterns sparking like fireflies on a summer evening‚ that produce movement‚ expression‚ words. Mental activity leads to changes of electrophysiological signals. The BCI system detects

Cerebral Cortex • Contains the cell bodies of neurons (gray matter) that control the voluntary activity of the body • The cortex is subdivided into 4 main lobe: – Frontal lobes (Control of muscle movement‚ the motor components of speech‚ abstract thinking & problem solving activity) – Parietal

Sensory neurons respond to an appropriate sensory stimulus with a change in membrane potential that is You correctly answered: b. graded with the stimulus intensity. 2. If the depolarization that reaches the axon is large and suprathreshold‚ the result in the axon is You correctly answered:

thinking‚ memory‚ and of detecting sensations (such as hot/cold‚ sharp/dull)‚ and others for vision‚ hearing‚ and other bodily functions. Basically‚ motor neurons provide voluntary movements and muscle power. As motor neurons degenerate‚ they can no longer send impulses to the muscle fibers that normally result in muscle movement. Motor neuron in ALS leads to their death so when it dies‚ the ability of the brain to initiate and control muscle movement is lost. Patient may become totally paralyzed

disorders than the classical acute form. In this pathway increased glutamate levels are not required as disturbances with the neuronal resting membrane potential cause glutamate receptors to be over-activated by physiological levels of glutamate. In a neuron which is affected by another pathological process and shows reduced ATP production‚ Na+ dysfunction or impaired glucose metabolism and as a result has an abnormal membrane potential‚ the voltage-dependent Mg2+ block within NMDA receptors may be eliminated

system is made up of your brain and the many different neurons that transmit signals to and from the body. One of the most common ways the nervous system deteriorates is when the connections between two neurons diminish‚ or build plaque. The brain uses neurons to send signals to each other‚ in order to get our bodies to move‚ think‚ and react to different situations. As people age‚ the neurons lose their normal functioning quality. Some neurons will deteriorate and be called Huntington’s disease‚
