...cortical spreading depression, which is thought to underlie many migraines. Even though the brains arteries expand dramatically and make a great deal more oxygen-rich blood available to meet the demand for energy, some parts of the brain still wind up experiencing severe oxygen shortage, or hypoxia.

...lses. It is key to the fast processing speeds that underlie our higher cognitive functioning, including, yes, wisdom. Myelination continues sheathing axons until we reach the age of about 50, but in these later stages, the myelin becomes more and more susceptible to damage.

... of the physical changes in brain cells thought to underlie memory, a discovery that is already uncovering clues about memory loss linked to cognitive disorders. Three decades of work by neuroscientists have established that a physiological effect known as long-term potentiation (LTP) encodes everyday forms...MIT reports key pathway in synaptic plasticity

Several key molecules are involved in normal synaptic formation, but their interactions are not well understood. Now MIT neuroscientists have taken an important step toward solving this challenging...Blocking stress protein decreases Alzheimer's peptide in mice

...d mutations in proteins in the DNA damage response underlie certain types of cancer and other disorders in humans. This work appears in the inaugural issue of Cell Stem Cell.

...rchers had thought that mutations were unlikely to underlie aging in blood-forming stem cells because they very rarely divide, and most mutations crop up during division. The infrequent divisions were believed to protect the cells from acquiring new mutations.
