Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.9K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Control Systems01:10

Control Systems

2.1K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Feedback control systems01:26

Feedback control systems

815
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

3.5K
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...

Somatosensation01:33

Somatosensation

45.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

6.4K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Area of Science:

  • Neuroscience
  • Perception science
  • Somatosensation

Background:

  • Accurate tactile perception is crucial for interacting with the environment.
  • Limb posture significantly influences tactile spatial processing.
  • Existing models do not fully explain rapid adaptation to novel postures.

Purpose of the Study:

  • To investigate the rapid adaptive mechanisms of tactile localization in novel limb postures.
  • To elucidate how the perceptual system adjusts to maintain accurate touch location under altered proprioceptive input.

Main Methods:

  • Participants performed tactile localization tasks with limbs in various novel postures.
  • Behavioral data on localization accuracy and reaction time were collected.
  • Computational modeling was used to analyze the adaptation process.

Main Results:

  • A rapid recalibration of tactile spatial maps was observed within minutes of adopting novel postures.
  • Adaptation significantly improved touch localization accuracy.
  • The speed of adaptation suggests a dynamic and efficient neural process.

Conclusions:

  • The perceptual system exhibits remarkable plasticity in adjusting tactile localization based on limb posture.
  • This rapid adaptation is essential for maintaining seamless sensorimotor integration.
  • Findings provide new insights into the neural basis of spatial awareness and proprioception.
