Applying Incongruent Visual-Tactile Stimuli during Object Transfer with Vibro-Tactile Feedback

2019
We present a protocol to apply incongruent visual-tactile stimuli during an object transfer task. Specifically, during block transfers, performed while the hand is hidden, a virtual presentation of the block shows random occurrences of false block drops. The protocol also describes adding vibrotactile feedback while performing the motor task.

Here we explore contralateral tactile masking between the forearms in which tactile detection thresholds are modulated by vibration applied to a remote site. The details of which remote sites have an effect can tell us about how the body is represented in the brain.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell! Since enzymes help control the rate of reactions, their activity is regulated so that appropriate amounts of starting materials, intermediate metabolites, and products are maintained in the cell. Excessive build-up or depletion of...

Tactile and Chemical Senses

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...

Specialized mechanoreceptors detect touch-related conditions such as pressure, vibration, texture, and skin stretch, then convert them into electrical signals. Considering these stimulus types separately helps neuroscience research relate particular environmental inputs to the information carried through sensory neurons and spinal pathways. This approach also connects physical contact with brain processing, movement, and object manipulation.
After mechanoreceptors generate electrical signals, sensory neurons and spinal pathways provide the route toward the brain. This transmission matters because tactile information must reach the brain for processing and integration with movement and other senses. Studying the pathway helps explain how touch-related signals contribute to coordinated responses to the physical environment rather than remaining isolated skin sensations.
Brain processing of touch-related signals contributes to awareness of the body and its physical surroundings. When integrated with movement and other senses, tactile information can support motor control and object manipulation. This makes pressure, vibration, texture, and skin stretch relevant not only as sensations, but also as inputs that help the nervous system interpret contact and guide interaction with objects.
Neuroscience research examines how signals detected at the skin relate to brain functions such as body awareness, motor control, and object manipulation. This perspective links peripheral detection with central processing and sensory integration. It helps researchers study how touch-related information participates in behavior and coordinated interaction with the physical environment, rather than treating touch as an isolated perceptual event.
Sensory prostheses and rehabilitation tools are relevant when the goal is to restore or reproduce touch-related information. Their development applies knowledge about mechanoreceptors, sensory pathways, and brain integration to engineered or therapeutic systems. These tools connect physical inputs with functions such as body awareness, movement, and object manipulation, making them important applications of neuroscience research on touch.
Haptic interfaces and robotic systems apply tactile-feedback principles to reproduce touch-related information in engineered settings. Sensory prostheses focus on restoring such information, while rehabilitation tools apply it in therapeutic contexts. Across these applications, pressure, vibration, texture, and skin stretch provide models for linking physical interaction with nervous-system processing, movement, and the handling of objects.
