Study Notes
Neuroplasticity and Motor Control
- Cerebral hemispheres play a role in motor learning and goal-directed behavior through the basal ganglia, mediated by dopamine.
- The motor cortex and basal ganglia work together to plan, select, and execute movement, with the motor cortex being the major output pathway for voluntary movement.
- Movement control involves subconscious planning, organization by the motor cortex and cerebellum, and feedback from peripheral sensory receptors.
- Movement emerges from the interaction of task, environment, and individual factors that constrain movement, such as action, perception, and cognition.
- The brain organizes movement differently based on task attributes like discrete vs continuous tasks, stability vs mobility tasks, manipulation continuum, and attention continuum.
- Taxonomy of environment includes regulatory features that directly shape movement and non-regulatory features that indirectly cause changes to movement.
- Neuroplasticity is the nervous system's ability to change or modify, involving shorter-term changes in synaptic connections and longer-term structural changes in the organization and numbers of connections among neurons.
- Neuroplasticity can occur at genetic, cellular, and whole-brain levels, leading to functional reorganization and changes in cortical maps in response to activity, behavior, and skill acquisition.
- Recovery from brain injury involves processes such as denervation super-sensitivity, synaptic hyper-effectiveness, and regenerative synaptogenesis in both the peripheral and central nervous systems.
- Functional reorganization at the network or systems level involves changes in cortical maps and the development of new functions in response to sensory input and motor demands.
- Cortical maps can change in healthy adults in response to activity, behavior, or skill acquisition, as well as after injury, such as amputation or central nervous system injury.
- The demand-driven nature of the nervous system leads to competition that determines the domination of neural borders and functional areas in the brain.
Neural Development and Circuitry Modification
- Neural induction, neurogenesis, and neuronal diversity are essential stages in full cell differentiation
- Disruptions in these processes can lead to congenital conditions such as spina bifida, anencephaly, and fetal alcohol syndrome
- The construction of neural circuits involves the integration of signals by neurons, leading to synaptogenesis or apoptosis
- Defects in neural processes can result in congenital neurological syndromes and developmental disorders
- Modification of neural circuits is influenced by genetic determination and experience, leading to variations in personality, ability, and behavior
- Critical periods of development, such as speech circuitry and vision, rely on neurotransmitter activity and receptor sensitivity
- Modifications in neural circuits, such as myelination, explain behavioral stereotypes and continue into the early 20s
- Problems with synaptic and circuitry modification may underpin conditions like autism, schizophrenia, or ADHD
- The brain's efficiency continues to improve into the early 30s, with linear increases in white matter and synaptic pruning post-puberty
- Adolescents are characterized by variations in the size of the amygdala and hippocampus, impacting emotional reactivity
- Grey matter decreases linearly from 4-18 years, while white matter increases linearly, impacting impulse control and risk-taking behaviors
- Social-emotional processing peaks at 16 years, while cognitive control systems linearly increase over time. In the second week, the lecture focused on motor control, highlighting the levels of motor control, including segmental, brainstem, and cerebellar levels.
Neuroplasticity and Human Development
- Neuroplasticity involves the use of redundant and uncrossed pathways in the brain to swap functions and activate secondary areas.
- Human adults may experience neurogenesis in the olfactory bulbs and hippocampus, but its usefulness for reparative processes in other brain regions is unknown.
- "Use it or lose it" principle: failure to use neural networks can lead to degradation of functions and learned non-use, requiring environments to be set up for increased engagement and stimulation.
- "Use it to improve it" principle: training or usage can maintain networks and connections, driving alternate processes and protecting plasticity.
- Synaptic connections strengthen via long term potentiation with cooperativity, associativity, and specificity conditions.
- Specificity principle: the nature of training dictates the nature of plasticity, and mere use is not enough.
- Repetition, intensity, timing, and salience all matter in inducing plasticity, and early intervention is critical.
- Age, transference, and interference all play roles in inducing plasticity and acquiring new skills.
- Human development involves changing relations between the developing person and multi-level environmental contexts.
- Developmental system perspectives and the lifespan perspective are important for understanding human development.
- Epigenetics can impact short and long-term health outcomes, and changes in gene expression can be transferred across generations.
- Growth involves changes in quantity and body size, with body proportions varying with age and impacting developmental motor control.
