Mémoire (psychologie)

thumb|350px|Les formes et fonctions de la mémoire en sciences. En psychologie, la mémoire est la faculté de l'esprit d'enregistrer, conserver et rappeler les expériences passées. Son investigation est réalisée par différentes disciplines : psychologie cognitive, neuropsychologie, et psychanalyse. thumb|Pyramide des cinq systèmes de mémoire. Le courant cognitiviste classique regroupe habituellement sous le terme de mémoire les processus dencodage, de stockage et de récupération des représentations mentales.

Le cortex moteur désigne l'ensemble des aires du cortex cérébral qui participent à la planification, au contrôle et à l'exécution des mouvements volontaires des muscles du corps. D'un point de vue anatomique, le cortex moteur est situé dans la partie postérieure du lobe frontal, au niveau de la région caudale de la circonvolution frontale ascendante en avant du sillon central. Le cortex moteur est en interaction constante avec d'autres structures nerveuses impliquées dans le mouvement comme le système des ganglions de la base et le cervelet.

Memory consolidation

Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term potentiation, occurs on a small scale in the synaptic connections and neural circuits within the first few hours after learning.

Explicit memory

Explicit memory (or declarative memory) is one of the two main types of long-term human memory, the other of which is implicit memory. Explicit memory is the conscious, intentional recollection of factual information, previous experiences, and concepts. This type of memory is dependent upon three processes: acquisition, consolidation, and retrieval. Explicit memory can be divided into two categories: episodic memory, which stores specific personal experiences, and semantic memory, which stores factual information.

Implicit memory

In psychology, implicit memory is one of the two main types of long-term human memory. It is acquired and used unconsciously, and can affect thoughts and behaviours. One of its most common forms is procedural memory, which allows people to perform certain tasks without conscious awareness of these previous experiences; for example, remembering how to tie one's shoes or ride a bicycle without consciously thinking about those activities.
