- 4 thins of asymmetrical brain:
- 1. asymmetries in the CC
3. fxns of the cc
4. fxns of lateralized
- What were the verbal and spatial tasks in the hemi diff in verbal and spatial processing task?
- Verbal: seen letters in one hemi, asked to say if probe letter matched previous
spatial: dot lateralized, have to say if circle was in the same location as the dot
- Verbal/spatial asymmetries task results:
- Splits: LH: much better for verbal
RH: much better for spatial
see little diff but sim better for controls
- Why is there any difference in the intact brain w/ a CC and the spatial and verbal R and L hemi task?
- Relying on the CC is good but cost performance wise,
info must be transfered across the CC and takes more time and more degradation
- What is callosal relay?
- interhemispheric transfer
- The right hand responds to the __ visual field faster than the __ visual field because:
- Right, left
interhemispheric transfer not needed
- What is uncrossed interhemispheric transfer?
- hemi gets the signal also controls the output and doesn't have to cross the info for performance to occur
- The brain is wired to transmit info to parts of the brain __ able to deal with info. Hemispehre ___ for the task
- best specailization
- Callosal realy has a decrease in __ and __
- degradation of info and time
- RVF input leads to better performance on __ tasks than LVF
- LVF input leads to better pefromance on ___ tasks than RVF
- Both ears project __ so both hemi receive stimulus and __ stimulus
- bilaterally, contralateral
- With dichotic listening there is competition so the __ pathway surpressed
- __ ear __> __ hemi (stronger listening)
- right, left
- __ hemi better at understanding speech and producing so the __ ear advantage
- left, right
- Hemi that controls writing is __ to handedness
- What test locates speech in the brain?
- Wada - puts 1 hemi to sleep and tests the other
