摘要
In Visual cortex layer II/III pyramidal neurons, lone-term depression (LTD) of synaptic currents was induced by a combination of the intracellular increase of inositol-1,4,5-trisphosphate (IP3), achieved by photolyzing caged-IP3, and the tetanization to nearby cortex, but not by either of these two procedures alone. A facilitatory role of an IP3-induced calcium release in LTD is suggested. (C) 2000 Elsevier Science Ltd. All rights reserved.
