Visual Properties of Neurons in a Polysensory Area in Superior
... Most STP units, 70% of the 199 tested, had little or no preference for stimulus size, shape, orientation, or contrast. These nonselective units would respond similarly to spots and slits of light, to shadows, to slides and photographs of complex objects, and to three-dimensional objects. Many of the ...

But the transition from neural activity to perception is not simple and remains largely unknown. This process is not intractable, however, and ...
