Premium Nervous system Neuron Brain
The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

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

Parkinson’s disease. Background information: In Parkinson’s disease‚ molecular mechanisms that function to mediate the deterioration of dopamine neurons located at the midbrain not clearly comprehended by many. In the pattern of a mouse of this disease‚ empirical evidence in support for the role of calcium-dependent protease‚ in the failure of dopamine neurons is provided

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

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
