Cellular Mechanisms of Learning and Memory
... PKA recruits the mitogen-activated kinase (MAPK) and together they translocate to the nucleus (long-term pathway), where PKA phosphorylates the cAMP-response element binding (CREB) protein. One gene activated by CREB encodes a ubiquitin hydrolase, which in turn cause persistent activity of PKA. The ...

... A stroke is a condition where a blood clot or ruptured artery or blood vessel interrupts blood flow to an area of the brain. A lack of oxygen and glucose (sugar) flowing to the brain leads to the death of brain cells and brain damage, often resulting in an impairment in speech, movement, and memory. ...
