Fine finger movements are controlled by the population activity of neurons in the hand area of primary motor cortex. Experiments using microstimulation and single-neuron electrophysiology suggest that ...

Engineers in Germany have built a biologically inspired artificial hand with muscles made from bundles of 'smart' wires. An electric charge is all that's needed to make these wires tense or relax, ...

AI and human-movement research intersect in a study that enables precise estimation of hand muscle activity from standard video recordings. Using a deep-learning framework trained on a large, ...

A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough ...

Human embryos are more muscle-bound than adult humans, new microscope images cataloging early development show. For instance, at seven weeks of gestation, embryonic hands have about 30 muscles. Adults ...

Split hand syndrome is a potential sign of amyotrophic lateral sclerosis (ALS). This means that some of the muscles in the hand are weak and thin (atrophied), while others are less affected.

The complex combination of movements required for this simple scissor gesture is a big step up from the capabilities of previous biohybrid robots. A biohybrid hand which can move objects and do a ...
