We do not see our blind spot because of two phenomena

This preview shows page 14 - 16 out of 16 pages.

We do not see our blind spot because of two phenomena: a) the right and left eye compensate for each other’s blind spot b) A later visual process step called perceptual fill-in provides the brain with the missing information by interpolating from the surrounding area. 4) Each eye’s optic nerve transmits information to both hemispheres of the brain Information from the left visual field (which arrives on the right side of each eye’s retina) travels to the right hemisphere of the brain , and information from

2. L ate V isual P rocess ( LVP ) The step in which sensation becomes perception. Occurs in the Occipital lobe at the primary visual cortex and at other visual association cortexes -Primary Visual Cortex : specialized region of cells that process particular visual attributes: a) Angles b) Colors c) Light d) Edges -Visual Association Cortex : interprets and understands 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 the temporal lobe. It helps with the identification of what an object is. b) Dorsal Pathway (Where) : Stream that projects from the primary visual cortex to the parietal lobe. It helps with the recognition of motion. c) Fusiform Face Area : Portion of the visual system located at the inferior medial temporal lobe between the collateral fissure and the inferior temporal gyrus responsible for attributing meaning/recognizing faces. d) Parahippocampal Place Area : Located in the medial temporal lobes on the collateral sulcus, the parahippocampal place area has been proven to predominately respond to Lesions to the Visual We don’t sense or perceive information directly Visual stimuli is altered/broken apart in the processing pipeline a) Compression b) Functional specialization in the primary visual cortex Lecture #9- Memory pt1 Memory 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 we organize information that we learn? 2. Storage : Retain encoded information- how do we keep what we know in the brain? How do we make the associations in our brain? 3. Retrieval : Outputting information stored in our brain. Ability to recover- How are memories recalled? Memory Systems 1. Sensory Memory : registers the most unprocessed form of information. Essentially a snapshot of the environment. a) Iconic Memory : Visual information held very briefly- fades within milliseconds.
