Evoked-Potential Correlates of Stimulus Uncertainty
The average evoked-potential waveforms to sound and light stimuli recorded from scalp in awake human subjects show differences as a function of the subject's degree of uncertainty with respect to theExpand

Developmental equations for the electroencephalogram.
Thirty-two linear regression equations predict the frequency composition of the electroencephalogram within four frequency bands, for four bilateral regions of the brain, as a function of age.Expand

Neurometrics: computer-assisted differential diagnosis of brain dysfunctions.
Normative developmental equations provide reliable descriptors of brain electrical activity in people 6 to 90 years old. Healthy persons display only chance deviations beyond predicted ranges.Expand

The clinical role of computerized EEG in the evaluation and treatment of learning and attention disorders in children and adolescents.
Quantitative EEG (QEEG) can play an important role in the evaluation and treatment of children and adolescents with attention deficit and learning disorders. Children with learning disorders are aExpand

Information Delivery and the Sensory Evoked Potential
TLDR
We show that the waveform of evoked responses recorded from human scalp is not determined solely by the physical eliciting stimulus, but also varies as a function of the effective information provided by the stimulus. Expand
