  Gastric content's mass and pH commonly assessed invasively using endoscopic
biopsy, or semi-invasively using swallowable transducer. EGG
(electrogastrography) is a technique for observing gastric myoelectrical
activity non-invasively, that could be designed as mobile device. In this
research, 72 EGG recordings were obtained from 13 local white rabbit
(Oryctolagus cuniculus). Recorded EGG processed using SCILAB 5.5.1 package.
Signal processing consists of waveform identification altogether with
recognition of resting, depolarization, ECA plateau, and repolarization
segments of each EGG in the time domain based on amplitude and temporal filter.
All rabbits were sacrificed after the recording in order to obtain its stomach
content's mass and pH data. EGG waveform generator based on gastric
morphological neuron assembly modeled using those data. If this model proved to
be accurate, the mass and pH from rabbit (Oryctolagus cuniculus)'s stomach
content could be assessed non-invasively, and could be a basis for human (Homo
sapiens) trial.
