After 50 years of research and the testing of over 1,000 drugs, there is new hope for preserving brain cells for a time after stroke. Treating acute ischemic stroke patients with an experimental neuroprotective drug, combined with a surgical procedure to remove the clot improves outcomes as show...
If brain cells are deprived longer, brain cells die, and some functions may be lost, sometimes permanently. How soon brain cells die after being deprived of blood varies. They die after only a few minutes in some areas of the brain but not until after 30 minutes or more in other areas....
Gray matter exists all throughout the various parts of the brain (as well as in the spinal cord); it consists of different types of cells, such as neurons. However, the brain also contains white matter, which comprises nerve fibers that connect the gray matter. The black component is ...

When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost. How a person is affected by their stroke depends on where the stroke occurs in the brain and how much the brain is damaged. For example, someone who had a ...
blood flow can damage brain tissue and, in severe or long-term cases, lead to serious neurological diseases. Brain ischemia, which is defined as a lack of oxygen and nutrients, causes the body to produce more inflammatory chemicals, which exacerbates t...
In an attempt to increase the potency of SCT, stem cells were permanently transfected with lentivirus (LV) encoding the IDUA gene. Following transfection, the LV vector copy number (VCN) of the stem cells ranged from 5 to 11 [121]. The FDA has established that the VCN must be < 5 for...
Deka’s blood flows gold rather than red. Deka is discovered and held in a cell where she is drained of her blood regularly. Now unable to die permanently, she suffers through several deaths while her blood is sold by the elite members of her village. When a strange woman arrives wielding...
Studies of the firing patterns of nucleus basalis neurons in nonhuman primates indicate that the cells are associated with arousing stimuli, both positive (appetitive) and negative (aversive). There is also evidence that the nucleus basalis promotes sustained attention, and learning and recall in long...
