Jan 4, 2023 · Think of the brain like the cast of a play or a musical. It has characters, or specific cell types, some of which are stars while others have supporting roles. They have names like neuron, astrocyte, microglia, interneuron, and oligodendrocyte. Several are utility players, performing different jobs depending on the scene. Brain cells begin to die in minutes. Another type of stroke is a hemorrhagic stroke. It occurs when a blood vessel in the brain leaks or bursts and causes bleeding in the brain. The blood increases pressure on brain cells and damages them. A stroke is a medical emergency. It's crucial to get medical treatment right away.Moreover, brain cholesterol horizontally transfers across various cell types not only to accommodate distinct cholesterol needs, but also to fulfill regulatory functions in target cells.
