Anyone who has sought out different methods for enhancing cognitive ability will probably have come across a technique known as Brainwave Entrainment. However, it is a fairly niche area of brain training, meaning that this form of stimulation is often overlooked in favour of more mainstream methods. The following outlines what Brainwave Entrainment actually is, how it is used, and some of the benefits attributed to it.
5) Your cerebral blood flow is being increased - CBF is associated with many forms of mental disorders, including anxiety, depression, attentional problems, behavior disorders and impaired cognitive function. CBF tends to lower as we age often causing cognitive decline. People experiencing depressed mood usually have lower levels of CBF in the left frontal and prefrontal lobes.
Theta stimulation: There appears to be no benefit associated with using theta stimulation for cognitive functioning, mood, or stress relief. While theta may be a useful way to induce sleep or alter your state of consciousness, there really isn’t much science supporting entrainment in this particular range for most purposes. Photic stimulation of theta between 5 Hz and 7 Hz can be useful for headaches.
Sir, am a user of subliminals from last 3 months. I’ve used subliminal with and without binaural beats.i found it more effective without binaural beats.and i got results too. But from last few weeks am listening to few subliminals with binaural beats.i donno why ..but i started feeling severe pain on my head and feels too tired and drowsy. I thought its because as it works. But my condition was getting worse. And also I started having fear and scary dreams. I started feeling like too stressed . I listen to 6 subliinals for 6 subjects a day. I read in a website its not a problem to listen 6 subjects a day.and i listen 6 subs for one hour each too…but in the starting i was happy with my results and subliminals.but now am getting scary dreams ..peaceless and fear. Why is this sir. Plse help me…but i love to use subliminals again as i got results. But am scared now. And plse also tell me sir if its okie to use subliminals without binaural beats?? Will they have same effect?? Help me sir…

Specific tones that resonate at certain frequencies are created and embedded within the acoustic architecture of the original waveform. Your brainwaves latch onto these embedded carrier frequencies and attune themselves to the same vibratory rate. Brainwave entrainment now occurs that is similar to binaural beats yet there is no need for headphones to deliver these entrainment effects.

Entrainment is a term originally derived from complex systems theory, and denotes the way that two or more independent, autonomous oscillators with differing rhythms or frequencies, when situated in a context and at a proximity where they can interact for long enough, influence each other mutually, to a degree dependent on coupling force, such that they adjust until both oscillate with the same frequency. Examples include the mechanical entrainment or cyclic synchronization of two electric clothes dryers placed in close proximity, and the biological entrainment evident in the synchronized illumination of fireflies.[13]
