Brain cells incude mostly neurons and glial cells. Neurons perform the processing and storage of information involved in brain function. Neurons are cells that are adapted to carrying the electrical signals called action potentials that are the basic building blocks of information transmission in the brain. They communicate to one another via synapses. Glia function to support and provide nutrition to neurons. Other cells in the brain include epithelial cells that make up the lining of blood vessels. Drawing by Santiago Ramón y Cajal of cells in the pigeon cerebellum. ... Neuroglia cells of the brain shown by Golgis method. ... Comparative brain sizes In animals, the brain, or encephalon (Greek for in the head), is the control center of the central nervous system. ... Cells in culture, stained for keratin (red) and DNA (green). ... A. A schematic view of an idealized action potential illustrates its various phases as the action potential passes a point on a cell membrane. ... Illustration of the major elements in a prototypical synapse. ... In zootomy, epithelium is a tissue composed of a layer of cells. ... The arterial system The blood vessels are part of the circulatory system and function to transport blood throughout the body. ...

Braincells are the only type of cells in the human body that do not regenerete.
Braincell transplantation with controlled-release nerve growth factor is demonstrated in rats by Cornell bioengineers
For example, the adult brain produces molecules that inhibit cell migration and the growth of axons (the part of the nerve cell that carries the nerve impulse) that could connect nerve cells, while scars that form on the glial (or connecting) cells after brain injuries also inhibit the elongation of axons.
Working with braincells, their plan was for some NGF to be released almost immediately, when the cells were implanted, while remaining amounts were to be released over a two-week period.
