A micro-doppler microscope for providing an indication of the vibration of a target. A language, behavioral and social disorder may be treated by detecting epileptiform activity or an electrographic seizure for a subject’s brain and applying neurostimulation to a language cortical region of the subject’s brain. A balance mechanism operatively connected to a display may be positionable between a storage position proximate the first side of the generally planar support surface and an exposed position proximate the second side of the generally planar support surface. The blood pump is powered by batteries or fuel cells to provide long service between recharging and to reduce the weight carried by the patient.
