Inverting the planning gradient: adjustment of grasps to late segments of multi-step object manipulations.

abstract：:The properties of the retinal ganglion cell classes in the cuban treefrog Hyla septentrionalis were studied qualitatively and quantitatively. In the superficial layers of the optic tectum three main classes of afferent optic nerve fibers could be distinguished, class-1*, class-3 and class-4 neurons. Hyla displays a mo...
