Main Topic: Enhancing the Nervous System

Nervous System

• Includes the brain, spinal cord, and connections with body organs
• Responsible for behaviors, emotions, experiences, and beliefs

Neuroplasticity

• Specific capabilities to change the nervous system
• Focus on motor commands and aspects of movement and balance

Types of Neurons

Lower Motor Neurons

• Located in the spinal cord
• Connect with muscles and allow their contraction
• Neural memory rather than muscle memory

Upper Motor Neurons

• Located in the motor cortex
• Send signals for deliberate actions
• Coordinate complex movements (e.g., making coffee)

Central Pattern Generators (CPGs)

• Located in the brainstem
• Generate repetitive movement patterns (e.g., breathing, walking)

Plasticity and Behavior

Changes in Behavior and Brain

• Different behavior can change the brain
• Need to send error signals to promote neuroplasticity
• Making mistakes as a signal to change neural circuits

Error and Learning

• Errors and frustration signal the brain that something needs to change
• Release of acetylcholine, epinephrine, and dopamine

Key Studies and Experiments

Eric Knudsen's Study

• Use of prism lenses to change the visual field
• Behavioral adjustments and plasticity in young and adult subjects
• Incremental learning is essential in adults

Importance of Dopamine

• Subjectively associates errors with positive outcomes
• Dopamine as a molecule associated with pleasure, motivation, and plasticity

Incremental Plasticity

• Importance of short learning periods (7-30 minutes)
• Contingency and need increase the rate of plasticity

Vestibular System

• Orientation of the body relative to gravity
• Generates the release of neurochemicals (dopamine, epinephrine, acetylcholine)
• Examples: inversions, yoga, sports with varied and novel movements

Practical Applications

Learning Strategies

• Balance limbic friction (alertness vs. fatigue)
• Use of physiological sighs and panoramic vision to calm down
• Oxygenated breathing and novel sensor/motor stimuli to wake up

Examples of Activities

• Using novel relationships with gravity to increase neuroplasticity
• Integrating vestibular movements into daily routines or exercises

Conclusion

• Neuroplasticity can be harnessed at any age
• Importance of small increments and crucial needs for learning
• Use of behavioral strategies and natural neurochemicals to improve learning
