What is Long-term memory?
'''Long-term memory''' (LTM) is our [[memory]] of past events. It follows from [[short-term memory]], and involves the growth of nerve [[synapses]] which are very long-lasting. == Types of LTM == The [[Human brain|brain]] does not store memories in one unified structure, as might be seen in a computer's [[hard disk drive]]. Instead, different types of memory are stored in different regions of the brain. Long term memory is typically divided up into two major headings: [[wikt:explicit|explicit]] memory and [[wikt:implicit|implicit]] memory.<ref name=Atkinson68>Atkinson R.C. & Shiffrin R.M. 1968.

''The psychology of learning and motivation'' '''2''': 89–195.</ref> === Explicit memory === Explicit or 'declarative' memory refers to memories which can be [[conscious]]ly recalled such as [[fact]]s and [[knowledge]]. These are partly encoded by the [[hippocampus]], stored elsewhere. Exactly where is unknown, but the [[temporal cortex]] has been proposed as a likely candidate. Research shows that [[amnesia]]c patients with damage to the [[medial temporal lobe]] performed more poorly on explicit learning tests than did healthy controls. However, the same patients performed at the same rate as healthy controls on ''implicit'' learning tests. This implies that the medial temporal lobe is heavily involved in explicit learning, but not in implicit learning.<ref>Meulemans, Thierry & Van der Linden, Martial 2003.
