Tactile Feedback

Tactile feedback is the perception of touch-related information, such as pressure, vibration, texture, and skin stretch, that helps the nervous system interpret and respond to the physical environment. Specialized mechanoreceptors in the skin detect these stimuli and convert them into electrical signals, which travel through sensory neurons and spinal pathways to the brain for processing and integration with movement and other senses. In neuroscience, studying tactile feedback clarifies how the brain supports body awareness, motor control, and object manipulation. These principles also guide the development of sensory prostheses, haptic interfaces, rehabilitation tools, and robotic systems that restore or reproduce touch.

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

0 Views •

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.

We describe two tactile sensory testing methods for acute or chronic periods of spinal cord injury in rats. These validated procedures can detect the development and maintenance of allodynia-like sensations.

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...
