PSYB57H3 Chapter Notes - Chapter 3: Inferior Temporal Gyrus, Visual Cortex, Two-Streams Hypothesis
Document Summary
Visual agnosia: an inability to identify objects visually even though they can be identified using other senses (e. g. , touch) damage to ventral pathway. Perception: the processing of sensory information in such a way that it produces conscious experiences and guides action in the world. Neural signals are transmitted by neurons through the optic nerve to the brain: primary visual cortex: are at the back of the brain, primarily responsible for basic processing of visual information. Retinotopic: a principle of organization of the primary visual cortex, whereby information falling on adjacent areas of the retina is processed in adjacent areas of the cortex. If part of the pvc is damaged, the result is blindness in the corresponding area of visual field. Bottom-up influences: feedforward influence of the external environment on the resulting perceptual experience: re-entrant (feedback) connections: connections between brain areas that allow propagation of visual information from endpoints of the ventral and dorsal pathways back to.
