Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
Integration of Synaptic Events01:28

Integration of Synaptic Events

Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...
Cerebral Hemispheres01:05

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
Reason and Intuition01:37

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...

Summary

Integrative movement neuroscience merges "inside-out" and "outside-in" research for a comprehensive understanding of posture and movement control. This convergence, aided by modeling, enhances insights into neural mechanisms across species.

Area of Science:

  • Movement Neuroscience
  • Neuroscience
  • Biophysics

Background:

  • Integrative movement neuroscience combines "inside-out" (cellular/circuit level) and "outside-in" (biomechanical level) approaches.
  • The "inside-out" approach examines central nervous system (CNS) properties and their influence on motor control.
  • The "outside-in" approach analyzes biomechanics to infer CNS mechanisms.

Purpose of the Study:

  • To explore the convergence of inside-out and outside-in methodologies in movement neuroscience.
  • To highlight the role of modeling and simulation in advancing the understanding of neural control of movement.
  • To discuss implications for training future movement neuroscientists.

Main Methods:

  • Review of historical studies on CNS circuitry for locomotion (invertebrates and vertebrates).
  • Analysis of research on treadmill locomotion in decerebrate cats.
  • Emphasis on modeling and simulation to integrate different research approaches.

Main Results:

  • A convergence of inside-out and outside-in approaches has been achieved in understanding neural control of locomotion.
  • Modeling and simulation studies have facilitated this integration across diverse species, including humans.
  • Historical research laid the groundwork for current integrative understanding.

Conclusions:

  • The integration of cellular and biomechanical approaches provides a more complete picture of motor control.
  • Future training programs for movement neuroscientists must emphasize interdisciplinary collaboration and computational skills.
  • University structures should foster interdisciplinary research to advance the field.
