EEG and EMG : Non-Invasive Tools for Diagnosis and Treatment

Biomedical signals are electrical signals acquired from any organ during its physical or mental activities. This signals are normally function of time and are describable in terms of their amplitudes, frequencies and phases. Electroencephalography (EEG) shows the state of the brain i.e. about the electrical bustle going on in the brain. These electrical activity measure as voltage at different points of brain and are basis of EEG.

Beside EEG, the EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction. The nervous system always controls the muscle activity (contraction/relaxation). The EMG signal is a complicated signal because is controlled by the nervous system. EMG signal acquires noise while traveling through different tissues. Moreover, the EMG device, particularly if it is at the surface of the skin, collects signals from different sources at a time which may generate interaction of different signals.

Detection and acquisition of EEG and EMG signals with powerful and advance devices have an important role in various phase of diagnosis, treatment and also biomedical engineering. So, the main reason for interests in EEG and EMG signals are clinical diagnosis and biomedical applications.

Pardis Technology Park

In a developing and knowledge based economy supporting infrastructure such as technology parks play an important role. This role is important not only because of micro-economy effects in supporting companies and firms, but also from macro economy approach, these kind of infrastructure converge limited source of countries right to the high tech section and thus resource proficiency will increase.

Pardis Tech Park (PTP), is main hub of innovation and technology in Iran and drive movement toward knowledge based economy. More than 250 knowledge and technology based companies have been supported by PTP under vice-presidency of science and technology of Iran.
