  2. Long-term memory - Wikipedia

    en.wikipedia.org/wiki/Long-term_memory

    Long-term memory. Long-term memory (LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to sensory memory, the initial stage, and short-term or working memory, the second stage, which persists for about 18 to 30 seconds. LTM is grouped into two categories known ...

  3. Long-term potentiation - Wikipedia

    en.wikipedia.org/wiki/Long-term_potentiation

    Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.

  4. Memory development - Wikipedia

    en.wikipedia.org/wiki/Memory_development

    The development of memory is a lifelong process that continues through adulthood. Development etymologically refers to a progressive unfolding. Memory development tends to focus on periods of infancy, toddlers, children, and adolescents, yet the developmental progression of memory in adults and older adults is also circumscribed under the umbrella of memory development.

  5. Memory consolidation - Wikipedia

    en.wikipedia.org/wiki/Memory_consolidation

    Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. [ 1 ] 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 ...

    Approximate number system. Parallel individuation system. v. t. e. Overview of the forms and functions of memory. Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. [1]

  7. Dendritic spine - Wikipedia

    en.wikipedia.org/wiki/Dendritic_spine

    A dendritic spine (or spine) is a small membranous protrusion from a neuron's dendrite that typically receives input from a single axon at the synapse. Dendritic spines serve as a storage site for synaptic strength and help transmit electrical signals to the neuron's cell body. Most spines have a bulbous head (the spine head), and a thin neck ...

  8. Muscle memory - Wikipedia

    en.wikipedia.org/wiki/Muscle_memory

    Muscle memory. Entering the same code into a keypad may, over time, become a muscle memory. Muscle memory is a form of procedural memory that involves consolidating a specific motor task into memory through repetition, which has been used synonymously with motor learning. When a movement is repeated over time, the brain creates a long-term ...

  9. Sensory memory - Wikipedia

    en.wikipedia.org/wiki/Sensory_memory

    Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. [2] A common demonstration of SM is a child's ability to write letters and make circles by twirling a sparkler at night. When the sparkler is spun fast enough, it appears to leave a trail which forms a continuous image.
