Summary
Our brains remap visual and auditory object locations across eye movements to maintain spatial constancy. This suggests a unified sensory map for tracking objects during movement.
Area of Science:
- Neuroscience
- Cognitive Science
- Sensory Integration
Background:
- The brain maintains spatial constancy by remapping visual object representations across saccades (rapid eye movements).
- It remains unclear if this remapping mechanism extends to auditory stimuli and contributes to cross-modal spatial stability.
Purpose of the Study:
- To investigate whether the brain's saccade-related remapping mechanism incorporates auditory and audiovisual information.
- To determine if auditory and audiovisual distractors influence eye movement trajectories similarly to visual distractors.
Main Methods:
- A double-step saccade task was employed to measure saccade trajectory curvature.
- Participants were presented with visual, auditory, or audiovisual distractors before or during the first saccade.
Main Results:
- Saccade trajectories systematically curved away from the location of visual, auditory, and audiovisual distractors.
- This effect persisted even when distractors were presented before the first saccade execution.
Conclusions:
- Oculomotor centers remap eye-centered representations of visual, auditory, and audiovisual objects across saccades.
- Evidence supports a supra-modal map that integrates multi-sensory object locations for spatial constancy during movement.

01:15Auditory Pathway
6.5K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:01Perception of Sound Waves
5.2K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

01:28Major Somatic Sensory Pathways
1.9K
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...

01:17Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

01:13The Cochlea
49.1K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
