Understanding Memory: A Detailed Overview

  • Memory is the faculty of the mind that encodes, stores, and retrieves data or information.

  • It is made up of sensory memory, short-term memory, and long-term memory.

  • Declarative memory is the conscious storage and recollection of data, while non-declarative memory is the unconscious storage and recollection of information.

  • Memory can be affected by various factors, such as pain, attention, physical damage to the brain, and decay over time.

  • Sensory memory holds information for less than one second after an item is perceived.

  • Short-term memory allows recall for a period of several seconds to a minute without rehearsal, with a capacity of 4-5 items.

  • Long-term memory can store much larger quantities of information for a much longer duration, potentially for a whole lifespan.

  • The multi-store model proposes that rehearsal is the only mechanism by which information eventually reaches long-term storage, but evidence shows us capable of remembering things without rehearsal.

  • The working memory model consists of three basic stores: the central executive, the phonological loop, and the visuo-spatial sketchpad, with the episodic buffer added later.

  • Researchers distinguish between recognition and recall memory, and declarative memory can be further sub-divided into semantic memory and episodic memory.Overview of Memory

  • Memory is the ability to encode, store, and retrieve information over time.

  • Declarative memory is used for abstract knowledge, while episodic memory is used for personal memories.

  • Procedural memory is used for remembering how to do something and is a subset of implicit memory.

  • Retrospective memory involves remembering information from the past, while prospective memory involves remembering future intentions.

  • Researchers use various techniques to assess memory in infants, children, and older adults.

  • The neuroanatomy of memory involves various brain areas, such as the hippocampus, amygdala, striatum, and mammillary bodies.

  • Long-term memory is dependent on the synthesis of new proteins, and DNA methylation and demethylation play a role in memory formation.

  • Epigenetic mechanisms, such as modifications of histone proteins, are involved in memory formation.

  • DNA topoisomerase II beta (TOP2B) activity is essential for the expression of immediate early genes (IEGs) in associative fear memory.

  • Double-strand breaks in promoter DNA of IEG genes are induced by TOP2B during learning experiences, allowing for the expression of these genes.Memory: An Overview

  • Contextual fear conditioning in mice causes hundreds of DNA double-strand breaks (DSBs) in the brain, activating genes involved in synaptic processes important for learning and memory.

  • Infants as young as 6 months can recall information after a 24-hour delay, and infants can store information for longer periods of time as they grow older.

  • Memory loss in normal aging is different from Alzheimer's disease, with older adults exhibiting deficits in tasks that involve knowing the temporal order of learned information and remembering specific circumstances or context.

  • Gene transcription profiles show a marked reduction in the expression of genes involved in memory and learning after age 40, especially after age 70, with a corresponding increase in DNA damage in their promoters.

  • Amnesia can result from extensive damage to specific regions of the brain, and studying different forms of amnesia provides insight into the brain's memory systems.

  • Stress can hamper memorization and retrieval through retroactive and proactive interference, but positive transfer can occur in certain situations.

  • Stress has a significant effect on memory formation and learning, with chronic stress producing hormones that impact the hippocampal structure in the brain and impairing memory recall in humans.

  • Sleep enhances memory consolidation by strengthening neural connections in the brain and stabilizing memories during slow-wave sleep (SWS).

  • Memories are constructed and can be distorted when people encode or recall them, as shown in the classic study by Loftus and Palmer.

  • The more stressful situations that someone encounters, the more susceptible they are to memory loss later on, and stressful life experiences can cause repression of memories and destruction of neurons in the hippocampal region of the brain.

  • Prenatal stress can hinder the ability to learn and memorize by disrupting hippocampal development and lead to unestablished long-term potentiation in offspring.

  • Short-term exposure to stress also impairs memory by interfering with the function of the hippocampus, and low-income children may display poorer memory performance due to the effects of stress accumulated over the course of their lifetime.

  • Viral infections, such as COVID-19, can elicit memory dysfunction.

  • Memory dysfunction can also occur in disorders such as hyperthymesia, Korsakoff's syndrome, and anomic aphasia.The Science of Memory

  • Imagining actions, events or repeatedly remembering them can result in false memories

  • Memories can be artificially implanted in mice

  • Memories are not stable and can be further strengthened or manipulated during the process of reconsolidation

  • Simple lifestyle changes such as healthy eating, physical fitness, and stress reduction can improve cognitive function and brain efficiency

  • The art of memory is a set of loosely associated mnemonic principles and techniques that can be used to improve memory

  • Memorization is a method of learning that allows an individual to recall information verbatim

  • The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time

  • Plants have neurotransmitters and memory systems that encode, store, and retrieve basic short-term memories

  • Venus Fly Trap plants exhibit rudimentary memory through cytoplasmic calcium levels

  • The field of plant neurobiology has gained interest over the past decade, leading to an influx of research regarding plant memory.
