- What was the Ungerleider and Miskin landmark and identity discrimination task?
- Showed a double dissociation as monkeys with temporal lesions could not do the identity task and monkeys with parietal lesions could not do the landmark task
- What is the difference between a single dissociation and double dissociation?
- Single dissociation: lesion to part A disrupts function X but not Y
DOuble dissociation: lesion to part A disrupts function X but not Y lesion to part B disrupts function Y but not X
- 3 reasons for separate pathways:
- 1. Require different kinds of information
2. Have different computational demands
3. Need special purpose machinery
- Describe the 6 layers of the LGN:
- Superior 4 are parvocellular (small cell) 2 R, 2 L
inferior 2 are magnocellular (large cell) 1 R, 1 L
- Retinal P-cells are __ in the fovea
- Parvocellular pathway is dominant input to the __/__ pathway
- 3 characteristics of the parvocellular pathway
- 1. slower conducting
2. color selective: b/c color important for object identity
3. high acuity
- Magno cells project to the magnocellular layer in the ___ and the __ __
- LGN and superior colliculous
- 3 characteristics of magnocellular pathway
- 1. fast conducting
2. no color code
3. low acuity
- Input from M-cells mostly in the __ and the domininant input to the __/__ stream
- periphery dorsal/where
- What technique did Broadman use to find different compartments within Area 17?
- Where does the convergence of the two eyes occur in the parvocellular pathway?
- interblobs - become binocular neurons
- What are Broadman's areas 18?
- V2 and V3 which are where blobs and interblobs lay - where the eyes converge of parvocellular layers
