Brainwave entrainment or " brainwave synchronization ," is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep), usually attempted with the use of specialized software . It purportedly depends upon a "frequency following" response on the assumption that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus. [ citation needed ] Such a stimulus is often aural, as in the case of binaural or monaural beats and isochronic tones , or else visual, as with a dreamachine , a combination of the two with a mind machine , or even electromagnetic radiation .

"Review of F.
"Why do emergent selves, virtual identities, pop up all over the place, creating worlds, whether at the mind/body level, the cellular level, or the transorganism level? This phenomenon is something so productive that it doesn't cease creating entirely new realms: life, mind, and societies.
‘Neurophenomenology : A Methodological Remedy for the Hard Problem’
(Part I is here , and part III is here ) In certain respects, development of the view that embodied experience is crucial to understanding the mind and brain reached a nadir in the period after World War II, at least within psychology. Behaviorism had redefined psychology as an “objective” science with no need to refer to consciousness or phenomenology.
I am currently an associate scientist at the Waisman Lab for Brain Imaging & Behavior at the University of Wisconsin-Madison.
The brain's center of reasoning and problem solving is among the last to mature, a new study graphically reveals. The decade-long magnetic resonance imaging (MRI) study of normal brain development, from ages 4 to 21, by researchers at NIH's National Institute of Mental Health (NIMH) and University of California Los Angeles (UCLA) shows that such "higher-order" brain centers, such as the prefrontal cortex, don't fully develop until young adulthood. A time-lapse 3-D movie that compresses 15 years of human brain maturation, ages 5 to 20, into seconds shows gray matter - the working tissue of the brain's cortex - diminishing in a back-to-front wave, likely reflecting the pruning of unused neuronal connections during the teen years.
Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we’re listening to.
Newly discovered neurons in the front of the brain act as the bouncers at the doors of the senses, letting in only the most important of the trillions of signals our bodies receive.
How accurate is the decoder?
