Biofeedback is the process of gaining greater awareness of many physiological functions of one's own body by using electronic or other instruments, and with a goal of being able to manipulate the body's systems at will.
The previous results of the researchers demonstrate that it is quite common for the reinforcement signals to lag behind changes in neuronal activity, leading to inefficient training and therapy and large scatter in biofeedback application.
Our approaches provide deep insights into brain & body functions and adjust them via real-time low latency (less than 100 ms) biofeedback, that allow the brain to perceive an artificially generated feedback loop as a part of its own neural network. Developing with input from experienced neuroscientists, professionals and industry leaders, they include proven neuroscientific principles and advanced machine learning algorithms based on 10+ years of academic research and aimed at improving human abilities & skills and achieving better outcomes in sports, study, professional & daily life, as well as medical therapy.

The dependence of the preservation degree of the training effect on the delay in the neurotransmission signal presentation
The comparative power of the occipital alpha rhythm measured after training in relation to the power before training turns out to be maximum with minimal delay.
There is a statistically significant trend.
Thus, the use of the GYRI BFB system provides an increase in the effectiveness of training & therapy in the biofeedback paradigm and measured as the magnitude of the power drop in the rhythmic activity of the user before and after training, as well as the steepness of the learning curve.

The low latency biofeedback system works as follows
The device are installed on the user: EEG electrodes are connected to the user's scalp, while other biosensors are connected to the user's face & body, the parameters for calculating and presenting the feedback signal are set via the user interface.
Then training begins: the user is presented with the visual, audio and other stimuli with a minimal time delay in accordance with his current brain & body state, that allows to adjust the user's psychophysiological and functional states or to carry out highly effective medical therapy.

The control signals forming the artificial biofeedback stimuli are generated by an onboard computer that receives EEG & other biosignals vectors in real time (with a delay less than the sampling interval) and performs algorithms for biosignal processing and allocation of the amplitude and phase of rhythmic brain activity with minimal delay and maximum secure. Then, the formed stimuli are offered to the user via high-frequency display, earphones and others. The total delay monitoring module calculates the total delay at each moment of time and stores the data.
Neurofeedback learning modifies the incidence rate of alpha spindles, but not their duration and amplitude
Although the first experiments on alpha-neurofeedback date back nearly six decades ago, when Joseph Kamiya reported successful operant conditioning of alpha-rhythm in humans, the effectiveness of this paradigm in various experimental and clinical settings is still a matter of debate. Here, we investigated the changes in EEG patterns during a continuously administered neurofeedback of P4 alpha activity. Two days of neurofeedback training were sufficient for a significant increase in the alpha power to occur. A detailed analysis of these EEG changes showed that the alpha power rose because of an increase in the incidence rate of alpha episodes, whereas the amplitude and the duration of alpha oscillations remained unchanged. These findings suggest that neurofeedback facilitates volitional control of alpha activity onset, but alpha episodes themselves appear to be maintained automatically with no volitional control – a property overlooked by previous studies that employed continuous alpha-power neurofeedback. We propose that future research on alpha neurofeedback should explore reinforcement schedules based on detection of onsets and offsets of alpha waves, and employ these statistics for exploration and quantification of neurofeedback induced effects.
Short-delay neurofeedback facilitates training of the parietal alpha rhythm
Objective. Feedback latency was shown to be a critical parameter in a range of applications that imply learning. The therapeutic effects of neurofeedback (NFB) remain controversial. We hypothesized that often encountered unreliable results of NFB intervention could be associated with large feedback latency values that are often uncontrolled and may preclude the efficient learning. Approach. We engaged our subjects into a parietal alpha power unpregulating paradigm facilitated by visual NFB based on the individually extracted envelope of the alpha-rhythm at P4 electrode. NFB was displayed either as soon as electroencephalographic (EEG) envelope was processed, or with an extra 250 or 500 ms delay. The feedback training consisted of 15 two-minute long blocks interleaved with 15 s pauses. We have also recorded 2 min long baselines immediately before and after the training. Main results. The time course of NFB-induced changes in the alpha rhythm power clearly depended on NFB latency, as shown with the adaptive Neyman test. NFB had a strong effect on the alpha-spindle incidence rate, but not on their duration or amplitude. The sustained changes in alpha activity measured after the completion of NFB training were negatively correlated to latency, with the maximum change for the shortest tested latency and no change for the longest. Significance. Here we for the first time show that visual NFB of parietal EEG alpha-activity is efficient only when delivered to human subjects at short latency, which guarantees that NFB arrives when an alpha spindle is still ongoing. Such a considerable effect of NFB latency on the alpha-activity temporal structure could explain some of the previous inconsistent results, where latency was neither controlled nor documented. Clinical practitioners and manufacturers of NFB equipment should add latency to their specifications while enabling latency monitoring and supporting short-latency operations.
