Researchers find protein that makes long-term memory possible
...olleagues reported in Nature that, in a laboratory simulation
using rodent brain cells, BDNF fostered changes in the cells indicative of memory. In 1998 Nobel laureate Eric Kandel reported that tissue plasminogen activator was also involved in the formation of long-term memory. Tissue plasminogen activator, o...
