Summary
- analyze EEG of stimulus at peripheral (8 to 16 degree), to determine the separate responses for central and peripheral fields
- no infant in this study had higher acuity in the peripheral field than in the central field
- well, the peripheral field is relatively more mature at birth
Methods
- central stimulus and semi-circle stimulus for the peripheral (8 to 16 degree). the peripheral stimuli subtended an area approximately 12 times larger than the central stimulus
- 39 infants, age 8 to 39 weeks
Results
- temporal frequencies may stimulate different temporal mechanism with different acuities, producing differences between responses
- responses properties might differ between foveal and periphery
- there might be an interaction between temporal frequency and electrode location
