In first instance, transient inactivation of AIP, by injecting a GABA-receptor agonist (muscimol) produced grasping errors only for difficult tasks that required a precision grip to grasp a small cube or a small sphere (as in the present experiment).
For compensatory grasping, we will analyse onset timing and magnitude of arm-muscle activation (biceps, medial deltoid), arm trajectory, and frequency of grasping errors (e.g, undershoot, overshoot, collision of hand with rail).
In the present paper, we apply an error-correction model of adaptation to experimental data of N = 40 participants grasping the Müller-Lyer illusion.
Third, based on a anatomical probabilistic map of the KNOB region, chimpanzees that make fewer grasping errors with their right compared to their left hand have larger leftward asymmetries in white matter.
The intrinsic grasp error of the micro-forceps without any tremor was measured with tremor compensation on after firmly attaching it to a rigid body (tool position fixed).
Only belatedly did the Prime Minister grasp the error of surrendering the power of decision to the Treasury.
He still didn't fully seem to grasp the error of his ways in his exit interview, despite several explanations and a comprehensive video review.
But to his credit, Mr. Spatz grasped that errors were made in Ms. Jahrling's case.
On the other hand, by defining new state variables based on the integral and differential of position and orientation errors of the grasped object, the error system of coordinated robot manipulators is constructed.
When an error in grasping the object was observed, subjects had to press a button with their right index finger; conversely, when the object was brought toward the incorrect slot, subjects had to press a button with their right middle finger.
