Neural Plasticity (opens the original)
Read excerpt
Neural plasticity is a normal property of the nervous system. In this episode, we look at how practice, learning, exercise, sensory experience, injury, and recovery can change neural function from the peripheral nervous system all the way to the brain. We cover changes in synaptic strength, potentiation and depression, structural changes at synapses, spinal cord processing, neural networks, cortical maps, and why the type of practice matters. The key idea: the nervous system is not fixed. Experi
Neural Fiber Types: Size, Speed, Receptors, and Function (opens the original)
Read excerpt
In this episode, we break down the major neural fiber types and connect their structure to their function. We compare the two major classification systems, examine how diameter and myelination affect conduction speed, and work through A-alpha, A-beta, A-gamma, A-delta, B, and C fibers along with their major receptors and roles in movement, sensation, pain, temperature, and autonomic function.

The Stretch Reflex (opens the original)
Read excerpt
What happens when a reflex hammer taps the patellar tendon? In this episode, Dustin Hardwick breaks down the stretch reflex from start to finish: tendon tap, muscle spindle , group Ia afferent , spinal cord, alpha motor neuron , and muscle contraction. Along the way, he reviews fiber types, conduction velocity, reciprocal inhibition, reflex latency , and how the stretch reflex compares with the withdrawal reflex . A concise overview for anyone studying movement science, neuroscience, kinesiology
From Thought to Movement: Overview of the Motor System (opens the original)
Read excerpt
Season 3 begins with a big-picture look at the motor system from the decision to move all the way to muscle force production. We trace movement through the cortex, corticospinal tract, spinal cord, motor units, and neuromuscular junction, then finish with how the nervous system grades force through rate coding and motor unit recruitment. This episode serves as the roadmap for the nervous system, motor control, and motor learning topics we’ll explore throughout the season. Links: Website Subst
