The paper uses fMRI to compare neural activation patterns during isolated prehension and prehension for object manipulation, finding distinct patterns involving visual and sensorimotor areas.

This study investigates how explicit and implicit information affects corticospinal excitability during hand-object interactions, finding that explicit cues improve performance but not excitability, while implicit cues do not influence either.

The paper investigates whether motor resonance is modulated by an object's weight distribution and finds that it is, during both observation and planning of lifting actions.

The paper shows that observing lifts of objects conveys weight distribution information, improving digit positioning strategies, but only error observations enhance predictive motor control for unexpected weight distributions.

The paper investigates the role of aIPS and LO in force scaling and weight perception during object lifting, finding no effect on force planning but time-specific changes in grip forces and weight estimation.

This paper investigates how weight expectations during object lifting observation modulate motor resonance, showing that pSTS suppression of motor resonance is critical for weight-based corticospinal excitability.

This study shows that observing skilled or erroneous lifts updates participants' internal sensorimotor object representation, enabling accurate predictive force scaling during subsequent lifts.
