Bad for memory and concentration: improve brain function

Section 1: Understanding of memory mechanisms and concentration

1.1. Memory neurobiology: the foundation of cognitive processes

Memory is not a single process, but a complex system that includes various types and stages. Understanding the neurobiological foundations of memory is the key to the conscious use of dietary supplements and other methods for its improvement.

  • Sensory memory: Short -term retention of information received from the senses (vision, hearing, touch). The fraction of a second lasts. Neural ties here are minimal and quickly disappear. Example: a fleeting look at the phone number.

  • Short -term memory (working memory): Holds the information for a short period (a few seconds or minutes) and allows you to manipulate it. The prefrontal cortex of the brain is actively involved. Used to solve problems, oral account and other cognitive operations. Example: memorizing a list of purchases.

  • Long -term memory: It stores information for a long time (days, months, years). Requires consolidation – a process in which short -term memories turn into long -term ones.

    • Declarative (obvious) memory: Contains facts and events that can be consciously recall.
      • Semantic memory: General knowledge about the world (capital of France, chemical formulas).
      • Episodic memory: Personal experiences and events (memories of birthday).
    • Non -coolate (implicit) memory: Includes skills and habits that are remembered unconsciously.
      • Procedure memory: Skills of action (cycling, playing a musical instrument).
      • Price: The influence of previous experience on current answers.
      • Classic determination: The formation of associations between stimuli (conditional reflex).

The main structures of the brain involved in the formation and storage of memory:

  • Hippocampus: He plays a critical role in the formation of new long -term declarative memories. Damage to the hippocampus leads to anterograd amnesia (inability to form new memories).
  • Amygdala: Participates in the emotional processing of memories. Emotionally significant events are better remembered.
  • Prefrontal bark: Is responsible for working memory, planning, decision -making and cognitive control.
  • Cerebellum: Participates in the formation of procedural memory and coordination of movements.

Neurotransmitters important for memory:

  • Acetylcholine: Plays an important role in teaching, attention and memory formation. A decrease in the level of acetylcholine is associated with Alzheimer’s disease.
  • Glutamate: The main exciting neurotransmitter in the brain. Participates in synaptic plasticity – a process underlying training and memory.
  • Gamk (gamma-aminobral acid): The main inhibitory neurotransmitter in the brain. It regulates the excitability of neurons and is important for the concentration and control of pulses.
  • Dofamine: Participates in motivation, reward and training. It is important for working memory and concentration.
  • Serotonin: Regulates mood, sleep and appetite. It is important for cognitive function and memory.

Sinaptic plasticity: The ability of synapses (contact places between neurons) to change its strength over time. Lies at the heart of training and memory. Long -term potential (LTP) and long -term depression (LTD) – two main mechanisms of synaptic plasticity.

1.2. Concentration mechanisms: focus of attention and cognitive control

Concentration is the ability to focus on a certain task or stimulus, ignoring distracting factors. It includes several cognitive processes:

  • Attention: Selective focusing on certain information.

    • Selective attention: The ability to choose what to pay attention to, ignoring other incentives.
    • Sustainable attention: The ability to maintain attention for a long period of time.
    • Separated attention: The ability to simultaneously focus on several tasks.

  • Working memory: Hold and manipulation of information in the mind.

  • Cognitive control: The ability to suppress impulsive reactions, switch between tasks and control your behavior.

  • Executive functions: Complex cognitive processes necessary for planning, organization and achievement of goals.

The main structures of the brain involved in the concentration:

  • Prefrontal bark: He plays a key role in monitoring attention, working memory and executive functions.
  • Parietal bark: Participates in spatial attention and processing of sensory information.
  • Talamus: Filters sensory information and directs it to other areas of the brain.
  • Front waist bark: Detects errors and conflicts, regulates cognitive control.

Neurotransmitters important for concentration:

  • Dofamine: It is important for motivation, attention and concentration. Dopamine deficiency is associated with the syndrome of attention deficit and hyperactivity (ADHD).
  • Norepinephrine: Enhances attention, vigilance and stress reaction.
  • Acetylcholine: It is important for attention and cognitive function.

Factors affecting concentration:

  • Dream: The lack of sleep worsens concentration and cognitive functions.
  • Stress: Chronic stress can negatively affect attention and memory.
  • Diet: Improper nutrition can lead to a deficiency of nutrients necessary for the normal functioning of the brain.
  • Physical activity: Regular physical exercises improve the blood supply to the brain and cognitive functions.
  • Medications: Some drugs can affect concentration and memory.
  • Age: Cognitive functions, including memory and concentration, can decrease with age.

1.3. Factors affecting memory and concentration: from lifestyle to genetics

The functioning of memory and concentrations is influenced by numerous factors that can be conditionally divided into the following categories:

  • Age: With age, a natural decrease in cognitive functions occurs, including memory and concentration. This is due to a decrease in the volume of the brain, a decrease in synapses density and a change in the level of neurotransmitters. However, the cognitive reserve, which is formed throughout life thanks to education, active mental activity and a healthy lifestyle, can compensate for these age -related changes.

  • Genetics: A genetic predisposition plays a certain role in cognitive abilities. Some genes are associated with the risk of developing neurodegenerative diseases, such as Alzheimer’s disease, which lead to serious memory disorders. However, genetics is not a determining factor, and lifestyle can significantly affect cognitive health.

  • Life:

    • Nutrition: A balanced diet, rich in antioxidants, omega-3 fatty acids and vitamins of group B, is necessary for normal brain function. The deficiency of nutrients can negatively affect memory and concentration.
    • Dream: The lack of sleep leads to a deterioration in cognitive functions, including attention, memory and decision -making. During sleep, memory consolidation occurs and brain cleaning of toxins.
    • Physical activity: Regular physical exercises improve the blood supply to the brain, contribute to neurogenesis (the formation of new neurons) and improve cognitive functions.
    • Mental activity: Constant training, problem solving and mental exercises stimulate the brain and support the cognitive reserve.
    • Social activity: Communication with other people, participation in social events and maintaining social ties contribute to cognitive health.
    • Stress management: Chronic stress can negatively affect memory and concentration. It is important to learn how to manage stress with the help of relaxation, meditation and other methods.

  • Medical conditions: Some medical conditions can affect memory and concentration.

    • Neurodegenerative diseases: Alzheimer’s disease, Parkinson’s disease and other neurodegenerative diseases lead to a progressive deterioration in cognitive functions.
    • Vascular diseases: Stroke, transient ischemic attacks and other vascular diseases can damage the brain and cause cognitive impairment.
    • Endocrine diseases: Diseases of the thyroid gland, diabetes and other endocrine diseases can affect cognitive functions.
    • Mental disorders: Depression, anxiety disorders and other mental disorders can worsen memory and concentration.
    • Deficiency of vitamins and minerals: The deficiency of vitamin B12, iron and other nutrients can lead to cognitive disorders.

  • Medicines: Some drugs can affect memory and concentration as a side effect.
