Two additional patterns, minuscule 28 per second positive spikes and huge N-shape potentials, have been identified exclusively in the EEGs of patients with 14 and 6 per second positive spikes. They occur predominantly during drowsiness and light sleep, usually in children, seldom in young adults. Their presence adds little to the clinical relevance of positive spikes. Familiarization with the N-shape potentials — the commoner of the two patterns — is important, lest they are mistaken for interictal abnormalities of significance such as atypical spike-wave complexes.
