A portable device utilizes an ultrasound probe, which is placed on the abdomen of a mother and allows ultrasound video and pictures, as well as Doppler heartbeat detection of the fetus. It is also capable of performing spontaneous brain activity recordings (referred here as fetal-EEG or fetal electroencephalography) and analyzing the fetal EEG measurements. The spontaneous electrical brain waves are detected by a sensor, amplified, digitized, and analyzed in one portable device, using analog and/or digital filters to improve the signal/noise ratio. The portable computer uses quantitative analysis software to compare the data from the fetus to normative data or to prior states of the fetus own data. The EEG signals are recorded for an extended period of time and can be analyzed in real time or at a later time for rhythmicity patterns indicative of epilepsy or other developmental brain disorders.
