Stable electrochemical patterns appear spontaneously around roots of higher plants and are closely related to growth. An electric potential pattern accompanied by lateral root emergence was measured along the surface of the primary root of adzuki bean (Phaseolus angularis) over 21 h using a microelectrode manipulated by a newly developed apparatus. The electric potential became lower at the poi...

Introduction Retinal input processing in the human visual system involves a phasic and tonic neural response. We investigated the role of the magno- and parvocellular systems by comparing the influence of the active neural population size and its discharge activity on the amplitude and latency of four VEP components. Method We recorded the scalp electric potential of 20 human volunteers viewi...

Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...

Insertional activity is examined by moving the needle through the muscle briefly and observing the crispness, size, and duration of the electrical potentials produced. These potentials are mechanically evoked injury potentials due to the advancement of the needle. After a brief, small movement of the needle, insertional activity will usually persist no more than 300 ms. However, this duration i...
