Our brains are made of billions of neurons, which are connected forming complex networks. They communicate between themselves by sending electrical signals, known as action potentials, and chemical signals, known as neurotransmitters, ...

Students of physiology are invariably taught that the primary function of myelin is to insulate nerves. In particular, to make action potentials more efficient by increasing the thickness of the membrane and thereby decreasing ...
When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. MIT neuroscientists have discovered a novel mechanism that contributes to the strengthening of these ...

(Medical Xpress)—When Descartes turned his critical eye to the nervous system, he reasoned that the nerves must transduce hydraulic power to control the musculature. In the circulatory system, blood is pushed comparatively ...
(Medical Xpress)—Pioneering experiments back in 1982 by Tasaki and Iwasa at the NIH revealed that action potentials in neurons are more than just the electrical blips that physiologists readily amplify and record. These ...
Astrocytes, as vital cells in the central nervous system, are crucial for brain health and function. Recent research shows that they influence higher cognitive functions and behaviors by regulating local neuronal activity.
