This study investigates how viscoelastic properties of human skin influence tactile neuron signaling during object manipulation, finding that neurons encode both current and past loading information.

The paper examines how participants manage gaze competition during object manipulation and environmental monitoring tasks, showing they prioritize sensorimotor control and adjust timing based on event statistics.

This paper shows human first-order tactile neurons signal edge orientation differences and maintain this signaling across various scanning speeds through sequential spike train structures.

The paper examines the spatial resolution of FA-1 and SA-1 tactile neurons using raised dots, finding their resolution corresponds to a spatial period of ~0.4 mm.

This study shows participants can quickly and accurately perceive edge orientation during object manipulation, with resolution better than 3 degrees and performance remaining high even with small edges.
