Study offers some details at cellular level

In order for us to use our minds for memory, for learning, and so forth, our brains must continually reinvent themselves. How do they do it? A Harvard Medical School research team has looked at the complicated interactions within nerve cells of ion channels, peptide hormones, growth factors, and a host of regulatory proteins and transcription factors. What they have seen is an amazing dance that requires exquisite timing. Their research was reported in the Oct. 12, 2001, issue of the journal Science. The research team was led by Michael Greenberg, Harvard Medical School professor of neurology at Children’s Hospital, and included Ricardo Dolmetsch and other colleagues.
