Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.3K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Somatosensation

41.2K
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.

Sensory Perception: Organization of the Somatosensory System

9.2K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Human Motor Control

Background:

  • Peripersonal space (PPS) is a crucial multisensory representation near the body, guiding interactions with the environment.
  • Existing research suggests PPS is body-part centered, but its distinction from arm-reaching space (ARS) remains unclear.
  • Confusion persists regarding the precise extent and behavioral characteristics differentiating PPS and ARS.

Purpose of the Study:

  • To directly contrast the spatial extent and behavioral features of peripersonal space (PPS) and arm-reaching space (ARS).
  • To investigate the underlying coding mechanisms of PPS and ARS using multisensory facilitation paradigms.
  • To refine theoretical models of PPS by clarifying its relationship with ARS.

Main Methods:

  • Five experiments (N=140) utilized gold-standard tasks and a novel multisensory facilitation paradigm to map PPS and ARS.
  • Multivariate analyses examined spatial patterns of multisensory facilitation in relation to hand position.
  • A control experiment ruled out attentional orienting as the primary driver of observed multisensory facilitation.

Main Results:

  • Peripersonal space (PPS) was found to be significantly smaller than arm-reaching space (ARS).
  • Multisensory facilitation patterns within ARS predicted hand locations, demonstrating hand-centered coding of PPS.
  • ARS mapping revealed a larger spatial extent with consistent patterns across hand positions, unlike PPS.

Conclusions:

  • Peripersonal space (PPS) and arm-reaching space (ARS) are distinct spatial representations with differing extents and coding.
  • PPS exhibits hand-centered coding, functionally similar to multisensory neurons observed in primates.
  • These findings necessitate a refinement of theoretical models concerning PPS, impacting self-representation and motor control.
