EEG with generalized slow activity
temporal intermittent rythmic delta activity
TIRDA
Temporal intermittent rhythmic delta activity (TIRDA) is an EEG pattern characterized by intermittent rhythmic sinusoidal bursts and trains of delta activity localized over the temporal regions
https://www.ncbi.nlm.nih.gov/pubmed/2804800
Modified definition
Occurrs more characteristically as trains of 50-100 µV sinusoidal or saw-toothed 1-4Hz activity, recorded predominantly from anterior temporal regions.
