Neural activity mapping with inducible transcription factors.

abstract：:It is difficult to induce long-term potentiation (LTP) in CA1 of hippocampal slices from 120-day-old rats when a single 100 Hz, 1 s tetanus is administered in extracellular solution containing 2.0 mM calcium and 2.0 mM magnesium. However, in the presence of 2.5 mM calcium and 1.3 mM magnesium LTP is reliably induced b...
