Demons can smell like sulfur, roses, cologne...anything! They can also appear as: an angel of light, a dead person or child, a spirit guide, a healing spirit (reiki), an alien, a fairy, a dwarf, a spirit animal etc! We can't safely discern them! The safest thing to do, is let Jesus and his angels protect us.
The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON: 10ms OFF) at a maximum tolerable level.
Thresholding sets a voltage level to separate burst and suppression events. If the EEG is. less than the threshold in the interval, the event is a suppression and is assigned a value of 1. whereas, if the EEG is greater than the threshold in the interval then the event is a burst and. is assigned a value of 0.
