In humans, age-related declines in vision, hearing, and touch coincide with changes in amplitude and latency of sensory evoked potentials. These age-related differences in neural activity may be related to a common deterioration of supra-modal brain areas (e.g., prefrontal cortex) that mediate activity in sensory cortices, or reflect specific sensorineural impairments that may differ between sensory modalities. To distinguish between these two possibilities, we measured neuroelectric brain activity while 37 young adults (18–30 years, 18 males) and 35 older adults (60–88 years, 20 males) were presented with a rapid randomized sequence of lateralized auditory, visual, and somatosensory stimuli. Within each sensory domain, we compared amplitudes and latencies of sensory-evoked responses, source activity, and functional connectivity (via phase-locking value) between groups. We found that older adults' early sensory-evoked responses were greater in amplitude than those of young adults in all three modalities, w...
