Answer 3

24 hours, continuing until seizure- free for 24 hours

Question 4

When monitoring neonates, modified placement of which electrodes allows the best visualization of background activity?

Answer 4

Frontopolar electrodes. FP3/FP4 sometimes used

Question 5

at what age do most children reach a PDR of 8Hz

Answer 5

36 months (3 years)
