1. Could water be used as a
sensor of brain activity?
Stoyan Vezenkov, Krasi Damov and Anton Antonov
South West University “Neofit Rilski”, BULGARIA
THE NINTH ANNUAL WATER CONFERENCE
9th TO 12thOCTOBER, 2014
in BULGARIA

2. Experimental design

3. Water vs. classical sensors

evaporating water
drops.
ANTONOV’S METHOD
Physiological sensors

4. Water energy spectrum data
(reading)
Differences of water energy spectrum put on the left hemisphere (LHS) and on the
right hemisphere (RHS) after reading.

5. Water energy spectrum data
(listening music)
Differences of water energy spectrum put on the left hemisphere (LHS) and on the
right hemisphere (RHS)
after listening music with closed eyes.
