Summary
This study shows that how we attribute motion (self vs. external) impacts both our perception of object movement and our body
Area of Science:
- Neuroscience
- Human sensorimotor control
- Perception
Background:
- Vestibular cues are thought to differentiate self-motion from external object motion.
- The role of this self-external attribution in sensorimotor responses, particularly touch, is not well understood.
Purpose of the Study:
- To investigate if self-external motion attribution influences sensorimotor responses during tactile interaction.
- To examine the link between motion perception accuracy and postural control.
Main Methods:
- Participants touched a moving object while standing on an unstable surface.
- Object motion direction judgment accuracy and postural responses were measured.
- The effect of object motion speed on postural sensitivity was analyzed.
Main Results:
- Postural sensitivity to object motion decreased with increasing motion speed.
- Erroneous motion perception led to increased postural responses.
- Results align with the hypothesis that attribution influences both perception and posture.
Conclusions:
- Self-external attribution of somatosensory motion plays a role in both object motion perception and postural control.
- This attribution mechanism integrates sensory information for coherent movement perception and balance.

01:28Major 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...

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

In the context of a rigid body's movement within a general plane, it is important to understand that this motion is typically triggered by external forces or couple moments exerted onto it. This principle can be explained through Newton's second law, which stipulates the translational motion of the body's center of mass along each axis.
Moreover, the body's center of mass experiences a rotational effect as a result of these couple moments. This rotation can be articulated as the...

01:33Somatosensation
36.4K
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.

01:10Relative Motion Analysis - Acceleration

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...
