Neurophysiology Of Object Perception

One way to study the nature of the processes and representations used in object perception is to examine the neural tissue of the visual system directly. Several means are available to do this: scientists may record from single neurons or selectively lesion brain areas in laboratory animals; they may work with human patients who have sustained damage to selective brain regions; or they may use functional brain imaging techniques to isolate the portions of normally functioning human visual systems that are engaged while performing various tasks. This section describes some of what we have learned about object perception via these methods.
