记忆通常被认为体现在神经元之间的连接强度上。起初,从数百万亿的记忆中找到负责记忆的确切突触连接似乎是不可能的。但新的研究可能会让我们更近一步。众所周知,新大脑皮层下的特定脑区是形成记忆所必需的(包括海马体和基底节),而与事实和知识有关的长期记忆(语义记忆)被认为驻留在新大脑皮层。然而,语义记忆的确切位置仍然未知,这阻碍了研究人员了解记忆是如何以及在哪里形成的。
Memories are generally considered to be embodied in the connection strengths between neurons. Finding the exact synaptic connections responsible for memories out of hundreds of trillions at first appears impossible. But new research may be taking us a step closer. Specific brain areas under the neocortex are known to be required for memory formation (including the hippocampus and basal ganglia), while long-term memory relating to facts and knowledge (semantic memory) is thought to reside in the neocortex . However, the precise location of semantic memory is still unknown, preventing researchers from understanding how and where memories are formed.
