							 This signal is derived from the hippocampus, a limbic structure
							that's involved in cognition of all sorts. 
							 
							You have two of them. On the right, it deals in non-verbal information processing including visualization and musical
							understanding. The hippocampus is implicated in psychic perception 
							 
							On the left, it's more linguistic. 
							 
							For most people, this signal is more pleasant when applied over the right. 
							 
							A few people are 'left-handed' or 'reversed' with respect to the hippocampus. If stimulation on the right side
							is unpleasant, try the left. 
							 
							The hippocampus is extensively connected to the frontal lobes. 
							If you find you are having moments where you have trouble recalling a word or name, or that you're a bit 'spaced
							out' at times, you should switch to another session design - one that stimulates the left side. 
							 
							The frontal lobes and the temporal lobes are the places best-suited to the hippocampal signal. 
							 
							Headaches can occur with this signal over the right side of the head. Usually, they stop after a few sessions,
							and respond to common headache remedies. They are more a sensation of pressure than a pain, and are not constant. 
							 
							The eight-coil Shakti unit is a powerful unit. It's suggested that you use it "symmetrically", meaning
							that you place the coils so that you are treating both sides of your head equally. If you choose to use it over
							only one side, you should use two of the coils to test each signal over each side, one side at a time, before you
							use the alternating signals over only one side. Make sure that you are not 'reversed' or 'left handed' with respect
							to any of the brain structures that the signals apply to. If unpleasant effects are going to occur, they will be
							milder than they would be using the 8-coil headset with alternating signals. 
							 
							The experiments shown in television documentaries applied the signals to both sides equally. If you are looking
							to induce spiritual experiences "as seen on TV", then you should also know that they were done in sensory
							deprivation. This means silence and darkness. Complete silence, and total darkness. 
							 
							 
							 
							When beginning to use any signal, it's a good idea to begin with shorter sessions. 
							 
							When you're planning to use a signal over only one side, it's good to try it over each side to see which side feels
							best with that signal for you.
