PSYB51H3 Lecture Notes - Lecture 4: Extrastriate Cortex, Fusiform Face Area, Illusory Contours
Document Summary
V1 cells are interested in the basic features of the visual image, responding to edges or lines of specific orientation/motion/size. Beyond the v1 is the extrastriate cortex (visual areas that lie just outside the primary visual cortex) From the extrastriate regions of the occipital lobe of the brain, visual information moves along two pathways. The second pathway leads down to the temporal lobe and is known as the what pathway and this pathway is important for object recognition. Agnosia the failure to recognize objects in spite of having th ebaility to see them. Inferotemporal cortex (it): is part of the cerebral cortex. Cells in the fusiform face area (ffa) are interested in faces. Prosopagnosia: is the inability to recognize faces. Feed forward process: process that carries out computation (object recognition) one neural step at a time, without the need for feedback from a later stage to an ealier stage.
