iPad Science Exploration: Visualizing Brainwave Entrainment

Brainwave entrainment or “brainwave synchronization,” is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (at least according to Wikipedia). I have a fascinating App on my iPad called simply Headache.  It’s introduction in the App Store reports, “Advanced Brainwave […]
