[6] [1] [3] Infiltration of lymphoma cells into the pons and medulla is the most frequently reported cause of CNH, accounting for half of all CNH-inducing brain tumors, despite its considerable rarity. It has been suggested that these lymphomas are capable of diffusely penetrating the midbrain, without significantly destructing the overall ...
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.

Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

The central nervous system (CNS) controls most of the functions of the body and mind. It comprises the brain, spinal cord and the nerve fibers that branch off to all parts of the body. The CNS viral diseases are caused by viruses that attack the CNS. Existing and emerging viral CNS infections are major sources of human morbidity and mortality.
Communication, i.e. aviation communication, refers to communication between two or more aircraft, the exchange of data or verbal information between aircraft and air traffic control and the ground based communication infrastructure of the ATM network (like the aeronautical fixed service). [2]
Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is a rare condition in which parts of the brain are affected by swelling, usually as a result of an underlying cause.
The San Francisco 49ers on Monday suspended linebacker De'Vondre Campbell for the final three games of the regular season for refusing to play Thursday night against the Los Angeles Rams.. Niners ...
Postsynaptic potentials are essential in how the brain processes information, integrates signals, and coordinates complex behaviors. These temporary changes in a neuron's membrane potential determine if a neuron will fire an action potential which allows neurons to communicate within neural circuits.
