Axonal conduction latencies of cat retinal ganglion cells in central and peripheral retina.

abstract：:Upright stance has allowed for substantial flexibility in how the upper limbs interact with each other: the arms can be coordinated in alternating, synchronous, or asymmetric patterns. While synchronization is thought to be the default mode of coordination during bimanual movement, there is little evidence for any bil...
