Do you hear what I see? How do early blind individuals experience object motion?
1Department of Psychology, University of Washington, Seattle, WA 98195-1525, USA.
Summary
Early blindness alters how the brain processes motion. The visual motion area (hMT+) is recruited for auditory motion, while the auditory area (planum temporale) shows reduced auditory motion selectivity.
Area of Science:
- Neuroscience
- Sensory processing
- Cortical plasticity
Background:
- 3D vision and object tracking are crucial.
- Early blind individuals demonstrate remarkable auditory motion perception.
- Cortical adaptation in blindness is not fully understood.
Purpose of the Study:
- Compare visual and auditory motion processing.
- Investigate the impact of early blindness on auditory motion perception.
- Explore cross-modal plasticity in motion processing.
Main Methods:
- Functional magnetic resonance imaging (fMRI) to study brain activity.
- Comparison of auditory motion processing in early blind and sighted individuals.
- Analysis of activity in visual motion area hMT+ and auditory area planum temporale.
Main Results:
- Early blindness leads to cross-modal recruitment of the visual motion area (hMT+) for auditory motion processing.
- The planum temporale, typically involved in auditory motion in sighted individuals, shows decreased selectivity for auditory motion in early blind individuals.
- Significant shifts in cortical activation patterns for motion perception were observed.
Conclusions:
- Early blindness induces substantial reorganization in the neural basis of motion processing.
- The recruitment of visual areas for auditory processing highlights the brain's adaptability.
- Understanding these cortical shifts is key to comprehending the perceptual experience of motion in early blind individuals.

01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:15Depth 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.
01:26Visual System
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
