A transcranial electrical stimulation device 1 having a wearing equipment 2 detachably worn onto a patient's head and at least a pair of electrodes 4 attached to the wearing equipment 2, the device for electrically stimulating a motor area of a patient's cerebral cortex by outputting current from the electrode 4 connected to a current generator. An engagement part 6 capable of engaging the wearing equipment 2 to a scalp with a thread-like body 8 is provided to the wearing equipment 2, and the electrode 4 is attached to the wearing equipment 2 protrudably to the head side of the electrode 4, and tip of the electrode 4 is capable of subcutaneously piercing through the head. It is unnecessary to bore a patient's skull outer layer with a drill, and a mounting of the electrode can be performed in a short time. The electrodes can be accurately positioned at predetermined positions of a patient's head, and the motor area of a cerebral cortex can be effectively stimulated.

Methods for fully automatic quantification and interpretation of three dimensional images of the brain or other organs. A system for Computer Aided Diagnosis (CAD) of diseases affecting cerebral cortex from SPECT images of the brain, where said images may represent cerebral blood flow (CBF). The methods include image processing, statistical shape models, a virtual brain atlas, reference databases and machine learning.

The present invention describes a method and apparatus to localize the electrical signals measured from a subject's scalp surface, preferably in near-real time, and to generate dynamic three-dimensional information of the electrical activity occurring within the cerebral cortex of the brain. In the preferred embodiment, it can produce images that can be immediately inspected and analyzed by an operator in near-real time, resulting in a powerful new cortical imaging modality, which we denote as Dynamic Electrocortical Imaging (DECI). The present invention involves the use of a computer, an electroencephalographic (EEG) amplifier, EEG electrodes, and custom software. It can measure healthy and diseased cortical events and states in both conscious and unconscious subjects. This is useful, as it allows for the diagnosis, monitoring and treatment of cortical disorders, while also furthering the understanding of the human brain and lending use to additional non-medical applications such as in entertainment, education, lie-detection and industry. The invention in one embodiment is implemented using software in conjunction with readily available EEG hardware. Furthermore, this same method can be applied to pre-existing data and when doing so, EEG hardware is not required. Having a practical near-real time 3D imaging system brings a far more accessible technology to doctors, researchers, individuals, and private clinics to better diagnose, monitor, treat and understand many of the conditions and abnormalities of the brain.
