Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

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.
Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Summary
This summary is machine-generated.

Newborn infants show a primitive coupling between visual flow and stepping. This suggests newborns can perceive and use visual information about self-motion, aiding early diagnosis of visual deficits.

Area of Science:

  • Developmental psychology
  • Neuroscience
  • Infant motor development

Background:

  • Newborn stepping is a primitive reflex.
  • The role of visual input in early motor control is not fully understood.

Purpose of the Study:

  • To investigate if optical flow influences newborn stepping.
  • To determine if newborns can use visual cues for self-motion perception.

Main Methods:

  • Forty-eight 3-day-old infants were tested.
  • Optical flow patterns (terrestrial, rotating, static) were projected above suspended infants.
  • The number of air steps elicited by each pattern was recorded.

Main Results:

  • Terrestrial optical flow significantly increased air steps compared to rotating or static patterns.
  • This indicates a rudimentary coupling between visual flow and stepping in newborns.
  • Newborns demonstrate a capacity to perceive and utilize visual information specifying self-motion.

Conclusions:

  • Newborn stepping can be modulated by optical flow.
  • This suggests a precocious visual-motor integration at birth.
  • Findings may inform early diagnosis of visual-motor deficits and visually-based interventions.
