摘要:
A method of facilitating a skill learning process or improving performance of a task, comprising: determining a brainwave pattern reflecting neuronal activity of a skilled subject while engaged in a respective skill or task; processing the determined brainwave pattern with at least one automated processor; and subjecting a subject training in the respective skill or task to brain entrainment by a stimulus selected from the group consisting of one or more of a sensory excitation, a peripheral excitation, a transcranial excitation, and a deep brain stimulation, dependent on the processed temporal pattern extracted from brainwaves reflecting neuronal activity of the skilled subject.

Decoding and reconstructing a subjective perceptual or cognitive experience is described. A first set of brain activity data produced in response to a first brain activity stimulus is acquired from a subject using a brain imaging device. An encoding model is used to convert the brain activity data into a corresponding set of predicted response values. A second set of brain activity data produced in response to a second brain activity stimulus is acquired from a subject and decoded using a decoding distribution derived from the encoding model, and the probability the second set of brain activity data corresponds to said predicted response values is determined. The second set of brain activity stimuli is then reconstructed based on the probability of correspondence between the second set of brain activity data and the predicted response values.

A method for analysis of the extent of conscious awareness and likelihood of recovery of a patient includes the steps of applying to the patient a sensory stimulus sequence which is typically auditory; carrying out an EEG to generate waveform signals to record changes in the electromagnetic fields generated by the patient's neural activity; using software provided in a processor to process the waveform signals in order to locate waveform peaks, identify the event-related potential (ERP) components obtained in the waveform and to obtain quantitative measures of those components; and using the software to generate and communicate scores indicative of the extent of conscious awareness and likelihood of recovery of the patient.
摘要:
A signal processing method and system combines multi-scale decomposition, such as wavelet, pre-processing together with a compression technique, such as an auto-associative artificial neural network, operating in the multi-scale decomposition domain for signal denoising and extraction. All compressions are performed in the decomposed domain. A reverse decomposition such as an inverse discrete wavelet transform is performed on the combined outputs from all the compression modules to recover a clean signal back in the time domain. A low-cost, non-drug, non-invasive, on-demand therapy braincap system and method are pharmaceutically nonintrusive to the body for the purpose of disease diagnosis, treatment therapy, and direct mind control of external devices and systems. It is based on recognizing abnormal brainwave signatures and intervenes at the earliest moment, using magnetic and/or electric stimulations to reset the brainwaves back to normality. The feedback system is self-regulatory and the treatment stops when the brainwaves return to normal. The braincap contains multiple sensing electrodes and microcoils; the microcoils are pairs of crossed microcoils or 3-axis triple crossed microcoils.

An in-ear stimulation system for administering caloric stimulation to the ear canal of a subject includes (a) a conduit configured to deliver a fluid to calorically stimulate an ear canal of a subject; and (b) a fluid control unit comprising a controller configured to control a flow of the fluid to the conduit and/or to control a caloric profile of the fluid such that a temperature of the fluid changes through time when the fluid is being delivered to the ear canal via the conduit.
摘要:
The invention relates to a method and apparatus for neural tissue detection carried out using the Neural Tissue Detector (NTD), which is the apparatus that embodies the hardware aspect of the invention. The NTD enables neural tissue detection by stimulating a small tissue area and by measuring possible occurrences of induced response from neural tissue, if neural tissue is present in said small stimulated tissue area. The information gathered by the measurement provides a real-time assessment of the nature of the tissue which is targeted by the NTD. The invention is applicable to all types of neural tissues, including motor, and/or sensory and/or other types of neural tissues. The invention offers particular advantages in robot based surgical procedures or intravascular catheter based procedures but can also be used for manual surgery, according to different specific embodiments.
摘要:
A noninvasive brain computer interface (BCI) system includes an electroencephalography (EEG) electrode array configured to acquire EEG signals generated by a subject. The subject observes movement of a stimulus. A computer is coupled to the EEG electrode array and configured to collected and process the acquired EEG signals. A decoding algorithm is used that analyzes low-frequency (delta band) brain waves in the time domain to continuously decode neural activity associated with the observed movement.

摘要:
The disclosure relates to a method for reconstructing the source of an electromagnetic field. Firstly, a measurement space separate from the source is selected so that the measurement space is connected to the source via a magnetically homogeneous spatial region. Measured values of the electromagnetic field emitted by the source are recorded on the surface of the measurement space so that the electromagnetic field in the measurement space can be uniquely determined in the context of an error bound determined by the discreteness of the measured values. A mathematical model of the electromagnetic source is developed which has a multiplicity of unknowns, and a system of equations is set up that relates the unknowns of the model to the measured values. The system of equations is solved in order to determine the characteristics of the electromagnetic source. The disclosure also relates to an arrangement for carrying out the method.
