The responses obtained during beat stimulation at 40 Hz and 16.3 Hz overlay almost perfectly.

( C) Group mean time series of oscillations at 10 Hz and 20 Hz. ( B) The topographic map of 10 Hz oscillations shows a dipolar pattern above the occipital lobe in an individual participant.
The time-frequency map was obtained as group mean across the maximally responding occipital sensors in n=5 individuals. ( A) Time-frequency map of the real part of phase coherence indicates strong synchronization of 10 Hz oscillations with the rhythm of the visual stimuli (top) as well as weaker synchronizations at multiples of 10 Hz during the time interval of RSVP stimulation. Therefore, auditory beats stimulation is a promising method of non-invasive brain stimulation for enhancing training and learning which is well-suited to rehabilitation training.Įntrainment of alpha oscillations through the rapid visual stimulation. The improvement becomes evident not immediately, but after consolidation during sleep. Taken together, 40-Hz BB stimulation during training accelerates the training outcome. In contrast, group B gained more from the 40 Hz stimulation on the second day than from 16-Hz stimulation on the first day. Group A improved more after the first day than the second day. However, participants improved between sessions, with overall improvement equal in both groups. The AB performance did not increase within a session. The rhythm of the visual stimulation elicited 10-Hz oscillations in occipital MEG sensors which were of similar magnitude for both BB frequencies. MEG recordings confirmed a strong entrainment of gamma oscillations during 40-Hz BB stimulation and smaller gamma entrainment with 16-Hz BB. Group A was presented with 40-Hz BB during the first day and 16 Hz during the second day, while the order of beat frequencies was reversed in Group B. Participants were assigned into two groups and presented with BB sounds while performing the AB task on three subsequent days in a cross-over design. Binaural beats (BB) are assumed to entrain neural oscillations and support cognitive function.

The AB refers to the lapse in detecting a target T2 in rapid serial visual presentation (RSVP) after the identification of a preceding target T1. This study investigated whether binaural beat stimulation could accelerate the training outcome in an attentional blink (AB) task.
