Altogether, these findings suggest that corticospinal output is modulated based on context-dependent information when mediated by explicit visual cues, but not when sensorimotor cues are presented in an implicit manner.

These differences between fingertip force scaling and weight estimation suggests that the transfer of weight information between hemispheres depends differently on the used hand and handedness for perception and action.
English
A perceptual bias in weight estimation was found depending on the previous object. However, transfer of this effect between hands was only seen in left-handers, not right-handers. Also, right-handers only had this bias when using their dominant hand.

Slow burn collaboration with @vvanpolanen and @marcodavare. We wanted to try and disrupt the brain areas possibly involved in the integration of prior expectations with perception and action. Perception unaffected by TMS, but some interesting effects on finger forces

In our quest to disrupt the size-weight illusion with #TMS over AIP, we found a very transient role of AIP in the sensorimotor predictions related to object size. Interesting because it implies another area takes over once force-to-size rules are learned.
