Area of Science:

Neuroscience
Robotics
Bioengineering

Background:

Incomplete recovery of sensation and motor control after spinal cord injury or amputation remains a challenge.
Current invasive neural interfaces have limitations in restoring full function.

Purpose of the Study:

To explore the feasibility of a novel biohybrid robotic hand for studying tactile sensation and sensorimotor integration.
To develop a pre-clinical research platform using biological neural networks (BNN) and an artificial hand.

Main Methods:

Coupled an artificial hand with BNNs cultured in a microelectrode array (MEA).
Decoded neural activity to control the robotic hand and encoded tactile sensations into mechanoreceptor patterns (RA/SA) for BNN stimulation.
Utilized a convolutional neural network (CNN) with transfer learning to classify neural activity.

Main Results:

Demonstrated functional specialization in BNNs based on different tactile encoding methods (RA vs. SA).
Achieved 97.84% accuracy in distinguishing between RA and SA encoding methods using CNN with tactile feedback.
Showcased the biohybrid hand's distinct robotic behaviors corresponding to different tactile feedback types.

Conclusions:

BNNs are sensitive to tactile encoding, integrating robotic sensations with artificial hand motor control.
This biohybrid platform offers a promising avenue for studying neural interfaces with reduced human risk.
