How do sound frequencies affect the brain?
Generally speaking, low-frequency waves are linked to “delta” and “ theta ” states which can boost relaxation and improve sleep. Higher frequencies reportedly boost your brain waves into a “ gamma ” state which may make you more alert, focused, or better able to recall memories.
Can the government read your mind?
Functional Magnetic Resonance Imaging (“fMRI”) technology produces a four-dimensional map of brain activity, such as perception, memory, emotion, and movement. If fMRI scans are privileged under the Fifth Amendment, the government cannot compel an individual to submit to the scan and reveal the contents of her mind.
What happens to your brain when you listen to brain waves?
In addition to passively monitoring his brain waves, the subject’s neurological processes may be affected by transmitting to his brain, through a transmitter, compensating signals. The latter signals can be derived from the received and processed brain waves.
How are brain waves measured?
The present art for measurement of brain waves employs electroencephalographs including probes with sensors which are attached to the skull of the subject under study at points proximate to the regions of the brain being monitored.
Can the brain communicate without synaptic transmissions?
“Researchers have thought that the brain’s endogenous electrical fields are too weak to propagate wave transmission,” said Dominique Durand, a biomedical engineer at Case Western Reserve University. “But it appears the brain may be using the fields to communicate without synaptic transmissions, gap junctions or diffusion.”
Is the brain using electrical fields to communicate?
“But it appears the brain may be using the fields to communicate without synaptic transmissions, gap junctions or diffusion.”. Running computer simulations to model their hypothesis, the researchers found that electrical fields can mediate propagation across layers of neurons.
