The extrastriate visual cortex can be divided into functionally distinct temporal and parietal regions, which have been implicated in feature-related ('what') and spatial ('where') vision, respectively . Neuropsychological studies of patients with damage to either the temporal or the parietal regions provide support for this functional distinction [2-4]. Given the prevailing modular theoretical framework and the fact that prefrontal cortex receives inputs from both temporal and parietal streams [5,6], recent studies have focused on the role of prefrontal cortex in understanding where and how information about object identity is integrated with (or remains segregated from) information about object location [7-10]. Here we show that many neurons in primate posterior parietal cortex (the 'where' pathway) show sensory shape selectivities to simple, two-dimensional geometric shapes while the animal performs a simple fixation task. In a delayed match-to-sample paradigm, many neuronal units also show significant differences in delay-period activity, and these differences depend on the shape of the sample. These results indicate that units in posterior parietal cortex contribute to attending to and remembering shape features in a way that is independent of eye movements, reaching, or object manipulation. These units show shape selectivity equivalent to any shown in the ventral pathway.
