Activity-dependent endocytosis of AMPA receptors at postsynaptic sites、which underlies long-term depression (LTD), is thought to mediate certain forms of learning and memory in vivo。However、whether LTD at synaptic levels is causally related to learning and memory at system levels has remained unclear。In thisNeuron paper、using a new optogenetic tool, termed PhotonSABER, which could acutely and reversibly inhibit LTD in a light-dependent manner、we show that LTD at parallel fiber-Purkinje cell synapses、is essential for eye movement-based motor learning in vivo。Dr. Kakegawa, Associate Professor at Keio University、and Dr. Matsuda, Associate Professor at the University of Electro-Communications、performed all experiments with great helps from Dr. Kato, Associate Professor (Tokai Univ.), Dr. Fukasawa, Professor (Fukui Univ) and Dr. Kohda, Professor (St. Mali University School of Medicine)。
