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
