半个多世纪以来,神经学家们一直以为长期记忆是由于多个短期记忆储存起来形成的。而最近一项对记忆形成的神经回路的研究则表明这一说法有可能是错的,因为两种类型的记忆(长期与短期)能够同时产生。这项研究是由来自MIT的研究者们做出。他们参考了此前标记特殊“记忆”细胞的手段,并更进一步地强制性使小鼠对特定的记忆作出反应,并且断开了长期与短期记忆的连接。 For more than half a century, neuroscientists have long believed that long-term memory is formed by the storage of multiple short-term memories. A recent study of neural circuits in memory suggests that this statement may be wrong because both types of memory (long-term and short-term) can occur simultaneously. The study was made by researchers from MIT. They refer to the previous means of tagging special “memory” cells and, further, forcing mice to respond to specific memories and disconnecting long-term and short-term memories.
