Alterations in retinal electrical responses, which arise from the neural retina, are one of the earliest manifestations of DR. ERG studies on diabetic animals have shown reduced a- and b-wave amplitude (Li et al., 2002), and prolonged implicit time in the oscillatory potentials (OPs) (Hancock and Kraft, 2004).
Simultaneous presentation of acoustic tones with electrical stimulation led to suppression of the electrically evoked response, which increased with increasing acoustic level.
Under the 'somatic electromotility' theory, mechano-electrical transduction modulates the OHC transmembrane potential, driving an OHC mechanical response which generates cycle-by-cycle mechanical amplification.
31– 35, 36, 36 Thus the observation that JR1 out-performs FM4-64, giving a fast response which is more than 5 times as voltage sensitive, implies that porphyrin-based dyes could be useful for detecting electrical signals in excitable cells.
I was in V-tach, and there was no electrical response in my heart, which leads to death.
Our investigations showed that the electrical response of PPy/Ag@BN nanocomposite which contains a conductor (Ag), an insulator (BN) and a semiconductor (PPy), was greater than that of polypyrrole.
Release of glutamate into the synaptic cleft induces transient postsynaptic electrical and biochemical responses, which can eventually promote stable changes in the properties of the neuron.
To evaluate the electrical response of each junction, a device simulation which couples both optical absorption and carrier transport are performed[17, 18].
A hydrogel of polyvinylamine cross-linking with Cu II) salts is employed as sensing material which has an ultrafast electrical response when it is exposed to water.
The optimization consisted in identifying which part of the electrical response and combination of sensing units yielded the best distinguishing ability.
