Head Direction, tTIS & Olfaction

How and when did your ability to perceive your surroundings and situate yourself accordingly evolve? Hint: It might have something to do with head direction. Also, how are scientists using a new neuromodulation technique by working around the frequency relations in the brain? ReferencesACT IMarcel E. Sayre, Ajay Narendra, Stanley Heinze, Andrew B.
