Recent studies show that prior to reaching, multiple potential reach targets are 26 encoded in brain regions involved in action control, and that when people are required to initiate 27 the reach before the target is specified, initial hand direction is biased by the spatial distribution 28 of potential targets. These findings have led to the suggestion that the brain, during planning, 29 simultaneously prepares multiple reaches to potential targets. In addition to hand direction, reach 30 planning often involves specifying other parameters such as wrist orientation. For example, when 31 posting a letter in a mail slot, both the location and orientation of the slot must be encoded in 32 order to control hand direction and orientation. Therefore, if the brain prepares multiple reaches 33
