Long-term memory stored in the cortex

'Where' and 'how' memories are encoded in a nervous system is one of the most challenging questions in biological research. The formation and recall of associative memories is essential for an independent life. The hippocampus has long been considered a centre in the brain for the long-term storage of spatial associations. Now, researchers have provided the first experimental evidence that a specific form of memory associations is encoded in the cerebral cortex and is not localized in the hippocampus as described in most neuroscience textbooks. The new study is a game changer since it strongly suggests that the motor cortical circuits itself, and not the hippocampus, is used as memory storage.
