Year: 1995

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
