Robotic art

In this era of quickly creating technology for medical imaging, a single test that could possibly look downright old-fashioned is an electroencephalogram (EEG) or brain-Wavetest. But by its pretty nature, EEG based robotic painter which uses nothing but brainwaves to create art. The goal of the Cognichrome is to artistically explore the promising filed of Brain to Computer Interface (BCI) and art. From art galleries to festivals.

As opposed to creating photos on the brain's anatomy, EEGs evaluate the brain's physiology. So whilst imaging tests won't replace electroencephalograms, EEGs won't replace imaging tests, either. The testing strategies look in the brain from completely distinctive points of view, each and every beneficial in its personal way.

Broken into its pWaves, the term electroencephalogram indicates "electrical brain recording."

Hans Berger, a German scientist, got the ball rolling in 1924 using the first recordings of human brain-Waves. Since then, the fundamental principles of recording EEGs have remained the identical, but the electronics have gotten better--and smaller. In an EEG recording, tiny voltage-fluctuations in the brain are picked up by a typical array of metal disks attached towards the scalp and are then amplified electronically to be able to create a permanent recording.

If you're old adequate, you could recall the 1960s fascination with alpha Waves which men and women tried to improve by means of biofeedback devices. Alpha Waves are rhythmic brain-signals oscillating in between eight and 13 times per second that can be measured from the back of your head during quiet wakefulness.

Further voltage-rhythms encountered for the duration of clinical recordings include things like theta and delta Waves that oscillate additional gradually than alpha Waves, and beta Waves that oscillate far more quickly. All 4 rhythms might be observed in normal states of alertness, drowsiness or sleep, and ought to be the identical on each sides with the brain.
