Stuttering-treatment techniques using neural stimulation and / or drug delivery. One or more electrodes and / or a catheter are implanted adjacent to sites in the brain. A signal generator and the electrode deliver stimulation to a first site. A pump and the catheter deliver one or more therapeutic drugs to a second site. The first and second sites could be: the supplementary motor area, the centromedian circuit, the dorsomedial nuclei, the lateral prefrontal circuit, or other paramedian thalamic and midbrain nuclei. The stuttering treatment could be performed via periodic transcranial magnetic stimulation. A sensor, located near the patient's vocal folds, can be used for generating a signal responsive to activity of the patient's speech-producing muscles. A controller adjusts one or more stimulation parameters in response to the signal from the sensor.

The invention discloses a mobile green plant decorative wall. The mobile green plant decorative wall comprises a base, and the base is of a hollow structure. Four universal wheels are arranged on theside wall of the lower end of the base, and the four universal wheels are separately located at four corners of the base. The base is of a hollow structure, and the base is internally provided with supporting mechanisms. The supporting mechanisms penetrate through the side wall of the base, and fixing mechanisms matched with the supporting mechanisms are arranged on the side wall of the base. A water tank is fixed to the upper surface of the base, and a water tank area is arranged in the water tank. Two motor areas are arranged in the water tank, and the two motor areas are separately disposedon two sides of the water tank area. Two telescopic mechanisms are vertically arranged on the upper surface of the base, and the two telescopic mechanisms are separately disposed on two sides of thewater tank. The mobile green plant decorative wall is no longer fixedly arranged in a room, but can be flexibly moved as needed, and the height of the green plant wall can be adjusted to increase thearea of green plant arrangement.

A method for extracting the duration of the cortical rest period, comprising: collecting the electromyographic signals of the hand muscles of the target hand and the opposite hand of the target; preprocessing the collected electromyographic signals; extracting the electromyographic signals in the preprocessed electromyographic signals The peak time point of the interference potential of the transcranial magnetic stimulation; the peak time point of the motor evoked potential is extracted; the energy value of each time point is calculated; the baseline energy value of the EMG signal is calculated; the duration of the cortical rest period is calculated. A fully automatic, single-shot method for extracting the duration of cortical rest periods, which can be used for the extraction of contralateral and ipsilateral cortical rest period durations. The invention is simple and fast in operation, without modifying parameters, and can obtain the duration of a single cortical resting period by inputting electromyographic signals, which can provide a method for transcranial magnetic stimulation to detect the performance of motor zone inhibitory pathways and corpus callosum inhibitory pathways Support, to a certain extent, can promote the application of cortical resting period in brain science research.

The invention discloses a brain function positioning method based on cortical EEG under electrical stimulation of the median nerve, and relates to the technical field of neuroengineering, comprising the steps of: giving electrical stimulation to the median nerve, and synchronously collecting cortical EEG data; Preprocessing the electrical data; analyzing the somatosensory evoked potential of the median nerve electrical stimulation to locate the central sulcus; analyzing the long-delay high-frequency gamma nerve response of the median nerve electrical stimulation to locate the functional area; comprehensively analyzing the location of the central sulcus and functional area As a result, sensory and motor functional areas are distinguished and localized. The brain function positioning method based on cortical EEG under the electrical stimulation of the median nerve of the present invention can quickly determine the positions of the central sulcus, the primary sensory cortex and the primary motor cortex by automatically judging the phase of the somatosensory evoked potential by the median nerve electrical stimulation; Electrical stimulation of long-latency gamma response enables stable and reliable localization of sensory and motor functional areas.

A motor imagery recognition system for a brain-controlled rehabilitation system that integrates complex networks and graph convolution. The subjects perform motor imagery by watching the video of hand clenching and stretching movements, and at the same time, the EEG signal acquisition equipment collects the subjects' motor imagery EEG brain Electrical signal; the movement intention recognition module constructs a multi-entropy complex network for the obtained motor imagery EEG EEG signal, extracts the characteristics of symbol fluctuation, frequency energy distribution and amplitude fluctuation in the motor imagery EEG EEG signal, and inputs the graph convolutional neural network Classify and identify the EEG signals of the fist-clenching movement and the EEG signal of the hand-stretching movement imagination, and transmit the classification results to the brain-controlled rehabilitation system, prompting the subjects to perform hand-clenching and stretching movements; the brain-controlled rehabilitation system The system enables the formation of a closed-loop pathway between motor intentions and body sensations, gradually enhances the subject's muscle strength and nerve conduction velocity, promotes the recovery of damaged brain motor areas, and gradually restores activity.
