Road Map for the Session Continuity Inter-hemispheric Synchrony Beta-Delta Complexes Temporal Theta Bursts Frontal Sharp Waves Reactivity to Stimulus Differentiation between sleep and awake eeg 4. Activity discontinuous in early life Long periods of electrical silence Presen in both sleep and awake records Seen till 30th week CA This pattern is referred to as Trace Discontinua 5. EEG activity becomes continuous during waking by 34 weeks CA EEG activity becomes continuous during NREM by 37 weeks CA However, semi-periodic, voltage attenuation still seen during NREM sleep, lasting for 1015 seconds Present upto 5-6 weeks of age 6. Road Map for the Session Continuity Inter-hemispheric Synchrony Beta-Delta Complexes Temporal Theta Bursts Frontal Sharp Waves Reactivity to Stimulus Differentiation between sleep and awake eeg 7. EEG activity asynchronous till 28 weeks CA Degree of asynchrony decreases with age, mature brain has minimal asynchrony 8. Road Map for the Session Continuity Inter-hemispheric Synchrony Beta-Delta Complexes Temporal Theta Bursts Frontal Sharp Waves Reactivity to Stimulus Differentiation between sleep and awake eeg 9. Beta-delta waveforms are composed of random wave forms 0.3-1.5 Hz frequency, superimposed on fast frequency Fast frequency in two frequency bands 8-12 Hz and 18-22 Hz Voltage
