influencing memory

Influencing memory: a comprehensive analysis of factors and mechanisms

I. Physiological foundations of memory

1. Neural networks and synaptic plasticity:

   • Definition and meaning: Memory, at the fundamental level, is the result of changes in synaptic connections between neurons. These changes, known as synaptic plasticity, allow neural networks to change their structure and functions in response to experience.

   • Mechanisms of synaptic plasticity:

     • Long -term potential (LTP): LTP is a process in which the repeating stimulation of the synapse leads to an increase in synaptic transmission. This mechanism is considered key to the formation of long -term memory. LTP includes an increase in the number of receptors on the postsynaptic membrane, a change in the morphology of synapses and the synthesis of new proteins.
     • Long -term depression (LTD): LTD, on the contrary, weakens the synaptic transmission. This process is important for removing unnecessary information and preventing oversaturation of neural networks. LTD can be induced by a weak, prolonged stimulation of the synapse.

   • The role of NMDA receptors: NMDA receptors activated by glutamate play a critical role in LTP and LTD. These receptors are sensitive to the coincidence of pre- and postsynaptic activity, which allows them to function as coinocation detectors necessary to strengthen or weaken synapses.

   • Structural changes in synapses: Sinaptic plasticity is accompanied by structural changes in synapses, such as a change in the size of the synaptic gap, the number of vesiculas with neurotransmitters and the number of receptors on the postsynaptic membrane. These changes can be long -term and underlying long -term memory.

2. Key areas of the brain involved in memory:

   • Hippocampus:

     • The role in the formation of new memories: Hippocampus plays a key role in the formation of new episodic and semantic memories. It functions as a temporary storage of information, which over time is consolidated in other areas of the brain.
     • Spatial memory: The hippocampus also participates in spatial memory and navigation. Neurons in hippocampus, called “neurons of places”, are activated when the animal is in a certain place in space.
     • Hippocampus damage: Damage to the hippocampus can lead to anterograd amnesia (inability to form new memories) and retrograde amnesia (loss of memories of events that occurred before damage).

   • Amygdala:

     • Emotional memory: The tonsil plays a key role in the formation and storage of emotional memories. It participates in the processing of the emotional significance of events and modulates the consolidation of memories in other areas of the brain.
     • Reaction fear: Almonds are especially important for the formation of a conditional reaction of fear. Damage to the tonsils can lead to impaired ability to recognize and respond to threats.

   • Prefrontal bark:

     • Working memory: The prefrontal bark plays an important role in working memory, which allows you to hold and manipulate information over a short period of time.
     • Executive functions: The prefrontal cortex also participates in executive functions, such as planning, decision -making and impulse control. These functions are necessary for the effective extraction and use of information from long -term memory.

   • Cerebellum:

     • Procedure memory: The cerebellum plays a key role in procedural memory, which includes skills and habits, such as cycling or playing a musical instrument.
     • Motor training: The cerebellum is involved in motor education and coordination of movements.

   • Cerebral cortex:

     • Storage of long -term memories: The cerebral cortex is a place of storage of long -term memories. Various areas of cortex specialize in storing various types of information, such as visual, auditory and language information.
     • Memory consolidation: The cerebral cortex is involved in the consolidation of memory, a process in which the memories are gradually stabilized and become independent of the hippocampus.

3. Neurotransmitters and memory:

   • Acetylcholine: Acetylcholine plays an important role in teaching and memory, especially in the formation of new memories. Acetylcholine deficiency is associated with a worsening memory in Alzheimer’s disease.
   • Glutamate: Glutamate is the main exciting neurotransmitter in the brain and plays a critical role in synaptic plasticity and the formation of memory.
   • Gamk (gamma-aminobral acid): GABA is the main brake neurotransmitter in the brain and plays an important role in regulating neural activity and preventing overexcitation.
   • Dofamine: Dopamine participates in training with reinforcement and motivation, which can indirectly affect memory.
   • Norepinephrine: Norepinephrine is involved in the regulation of attention and emotional excitement, which can modulate the consolidation of memories.

II. Types of memory

1. Sensory memory:

   • Iconic memory (visual): Short -term storage of visual information (less than a second).
   • Echoic memory (auditory): Short -term storage of auditory information (up to several seconds).

2. Short -term memory (short -term storage):

   • Definition and capacity: A short -term memory, also known as working memory, allows you to hold and manipulate information for a short period of time (usually a few seconds). The capacity of short-term memory is limited to approximately 7 +/- 2 elements of information.
   • Working memory: Working memory is a more complex system than just a short -term storage. It includes components that allow you to actively process information, such as a phonological loop (for storing and repeating verbal information) and a visual and spatial notebook (for storing and manipulating visual and spatial information).
   • Central Artist: The central performer controls attention and coordinates the activity of a phonological loop and a visual-spatial notebook.

3. Long -term memory:

   • Explicit (declarative) memory:

     • Episodic memory: It stores information about specific events and experiences related to a certain time and place (for example, memories of the latest vacation or the first day at school).
     • Semantic memory: It stores general knowledge about the world, facts, concepts and meanings of words (for example, knowledge of the capital of France or the meaning of the word “photosynthesis”).

   • Implicit (non -coolate) memory:

     • Procedure memory: It stores information about skills and habits, such as cycling, swimming or playing a musical instrument.
     • Price: The influence of previous experience on current behavior or perception.
     • Classical conditional reflection: Training in associations between incentives.
     • Non -accerative training (addiction and sensitization): Changing the reaction to the stimulus after repeated exposure.

III. Factors affecting memory

1. Age:

   • Age -related changes in the brain: With age, there are changes in the brain that can affect memory. These changes include a decrease in the volume of the brain, a decrease in the number of neurons and synapses, as well as a decrease in the level of neurotransmitters.
   • Age -related changes in memory: With age, working memory, episodic memory and speed of information processing may worsen. Semantic memory and procedural memory often remain relatively preserved.

   • Different stages of sleep and memory: Various stages of sleep, such as slow sleep (SWS) and a quick sleep (REM), play a different role in the consolidation of various types of memory. SWS is important for the consolidation of declarative memory, and Rem Sleep is important for the consolidation of procedural memory and emotional memory.
   • Lack of sleep and memory: The lack of sleep can worsen memory, attention and cognitive functions.

3. Stress and anxiety:

   • The effect of stress on the hippocampus: Chronic stress can damage the hippocampus, which can lead to a deterioration in memory and cognitive functions.
   • Cortisol and memory: Cortisol, stress hormone, can affect memory. A short -term increase in the level of cortisol can improve the consolidation of memories, but a prolonged exposure to a high level of cortisol can damage the hippocampus and worsen memory.
   • Anxiety and memory: Anxiety can worsen attention and working memory, which can complicate the process of training and memorizing information.

4. Nutrition:

   • The role of nutrients in the health of the brain: Nutrition plays an important role in the health of the brain and cognitive functions. The lack of certain nutrients can worsen memory and cognitive functions.
