Artist manipulates 48 pools of water with Brain Waves
In her own words:
“Eunoia” is a performance that uses my brainwaves — collected via EEG sensor– to manipulate the motions of water. It derives from the Greek word “ey” (well) + “nous” (mind) meaning “beautiful thinking”. EEG is a brainwave detecting sensor. It measures frequencies of my brain activity (Alpha, Beta, Delta, Gamma, Theta) relating to my state of consciousness while wearing it. The data collected from EEG is translated in realtime to modulate vibrations of sound with using software programs. EEG sends the information of my brain activity to Processing, which is linked with Max/MSP to receive data and generate sound from Reaktor.
“I believe that human emotions come with corresponding waves of energy that we carry within,” Park says in the video. Eunoia II metaphorically gives those waves faculty and visibility, continuing the exploration she began in her first Eunoia performance.
Evidence to Marijuana's potential role in fighting Alzheimer's.
With a drug war against marijuana still raging in more countries than not, the question of how long-term marijuana use effects the human brain is a pivotal question in its legalization.
Luckily, the debate can finally move out from the realm of opinion into scientific evidence as researchers from the University of Texas just published their research into the long-term effects of marijuana use on the brain in PNAS (Proceedings of the NationalAcademy of Sciences).
The researcher helped dispel the dying myth that marijuana use lowers IQ, and actually provides more evidence to marijuana's potential role in fighting Alzheimer's.
The research revealed that earlier onset of regular marijuana use leads to greater structural and functional connectivity in the brain. The most significant increases in connectivity appear as an individual begins using marijuana, with results showing that the severity of use is directly correlated to greater connectivity.
Although these results will need to be confirmed with a larger sample (this was based on roughly 100 participants), the preliminary results do seem promising. More research will need to be done in order to see if these differences are caused by, or simply associated with, long term marijuana use.
They also found reduced gray matter in the OFC (orbitofrontalcortex) in long-term users (which is a brain region associated with addiction), it is unclear whether this region is simply smaller in regular users (explaining their regular use) or if the use actually contributed to structural brain changes. These results will also need to be contrasted with other researcher showing that cannabinoids actually promote brain cell growth (neurogensis) even in adults.
