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.
