Description of data sets: Burns -- reaching with head tilt and left/right visual perturbations Fernandes -- reaching with uncertain and rotated midpoint feedback Kording -- reaching with uncertain midpoint feedback Mattar 07 -- generalizing from one, two or multi targets to another direction Mattar 10 -- reaching to a distance (short/long), generalizing to the other one (long/short) Ostry -- move in force field, get an estimation of where the hand is Scott -- monkey (no spike), center out: even and not evenly distributed targets, also a forward/back Stevenson -- center out, monkey with neural time stamps Vahdat -- movement in force field with FMRI scans pre/post learning Wei 08 -- visual perturbations, cursor shown only at target Wei 10 -- movement in differing force fields Young -- movement time stayed the same, but distance changed; fast, medium, slow reaches.
