Optogenetics: Controlling the Brain with Light [Extended Version] Despite the enormous efforts of clinicians and researchers, our limited insight into psychiatric disease (the worldwide-leading cause of years of life lost to death or disability) hinders the search for cures and contributes to stigmatization.

Clearly, we need new answers in psychiatry. But as philosopher of science Karl Popper might have said, before we can find the answers, we need the power to ask new questions. In other words, we need new technology. Wetware Hacker - Advanced. Binaural Beats Click to Play Binaural Beats are an auditory form of brainwave entrainment.

When two signals are sent, one to each ear, and the signals differ by thirty hertz or less, the frequency follow response is evoked. It is important that the signals are identical except for this desired entrainment frequency, and nominally headphones are used. Discovered in the 1800's by a meteorologist named Heinrich Wilhelm Dove, the difference in signals affects the brainstem's superior olivary nucleus, the site of contralateral integration of auditory input. Virtual retinal display. A diagram showing the workings of the virtual retinal display A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye.

The user sees what appears to be a conventional display floating in space in front of them. (However, the portion of the visual area where imagery appears must still intersect with optical elements of the display system. It is not possible to display an image over a solid angle from a point source unless the projection system can bypass the lenses within the eye.)
