Medial Temporal Lobe (MTL)

A brain region essential for memory formation, consisting of structures like the hippocampus and entorhinal cortex.

Hippocampus

A crucial area for memory formation and consolidation.

Parahippocampal gyrus

Involved in processing spatial information and memory.

Entorhinal cortex

Acts as a relay between the hippocampus and neocortex, playing a role in memory encoding and retrieval.

Perirhinal cortex

Involved in object recognition and memory.

Cornu Ammonis (CA) regions

Subdivisions of the hippocampus (CA1, CA2, CA3, CA4) involved in different aspects of memory processing.

Long-Term Potentiation (LTP)

A process that strengthens synapses based on recent patterns of activity, crucial for learning and memory consolidation.

Synaptic consolidation

The initial phase of memory stabilization at the level of synapses, occurring in the hours after learning.

Systems consolidation

The reorganization of memories across different brain regions over a longer period.

Reconsolidation

The process by which previously consolidated memories become labile again upon retrieval.

False Memory

A recall of an event that did not occur; a result of the constructive nature of memory.

Episodic Memory

Memory of personal experiences and specific events, including their time and place.

Semantic networks

Models of knowledge representation where concepts are interconnected.

Highly Superior Autobiographical Memory (HSAM)

A rare condition that allows individuals to recall nearly every detail of their personal past with high precision.

Context-dependent memory

The improved retrieval of information when the context in which it was learned is re-encountered.

Mood-congruent memory

The phenomenon where a person's mood at retrieval can aid in the recall of memories consistent with that mood.

Distributed representation

A theory that semantic information is spread across multiple brain regions.

Hub-and-spoke model

A model suggesting the anterior temporal lobe acts as a hub for semantic memory, interacting with other regions for sensory and motor information.

Autobiographical Memory (AM)

Memory about oneself, consisting of personal memories (episodic) and general knowledge about oneself (semantic).
