We do not see our blind spot because of two phenomena:a)the right and left eye compensate for each other’s blind spotb)A later visual process step called perceptual fill-inprovides the brainwith the missing information by interpolating from the surroundingarea.4)Each eye’s optic nerve transmits information to both hemispheres of the brainInformation from the left visual field (which arrives on the right side of eacheye’s retina) travels to the right hemisphere of the brain, and information from
2. Late Visual Process (LVP)The step in which sensation becomes perception.Occurs in the Occipital lobe at the primary visual cortex and at other visualassociation cortexes-Primary Visual Cortex: specialized region ofcells that process particular visual attributes:a)Anglesb)Colorsc)Light d)Edges-Visual Association Cortex: interprets andunderstands visual information: attributes meaning to what we see.-Different Processing Streams in the Association:a)Ventral Pathway (What): Stream that projects from the primary visual cortex to thetemporal lobe. It helps with the identification of what an object is.b)Dorsal Pathway (Where): Stream that projects from the primary visual cortex to theparietal lobe. It helps with the recognition of motion.c)Fusiform Face Area: Portion of the visual system located at the inferior medial temporallobe between the collateral fissure and the inferior temporal gyrus responsible forattributing meaning/recognizing faces.d)Parahippocampal Place Area: Located in the medial temporal lobes on the collateralsulcus, the parahippocampal place area has been proven to predominately respond toLesions to the Visual We don’t sense or perceive information directlyVisual stimuli is altered/broken apart in the processing pipelinea)Compressionb) Functional specialization in the primary visual cortexLecture #9- Memory pt1Memory is pervasive, some aspect of memory is involved in everything that we do.Stages of Memory
1.Encoding: Input information to memory- What are the best ways to learn? How do weorganize information that we learn?2.Storage: Retain encoded information- how do we keep what we know in the brain? Howdo we make the associations in our brain?3.Retrieval: Outputting information stored in our brain. Ability to recover- How arememories recalled?Memory Systems1.Sensory Memory: registers the most unprocessed form of information. Essentially asnapshot of the environment.a)Iconic Memory: Visual information held very briefly- fades within milliseconds.
