Methods of Tissue Engineering
CHRONAXIE. (C50). Myooids are cultured aneurally and do not exhibit
excitability typical of adult muscle. As a consequence, electrical stimulation
pulses required to elicit maximal twitch and tetanus are generally an order of
magnitude ...

Intermediate Physics for Medicine and Biology
The strength-duration curve for current was first described by Lapicque (1909) as
i = iR ( 1+ tC t ) , (7.45) where i is the current required for stimulation, iR is the
rheobase, t is the duration of the pulse, and tC is chronaxie, the duration of the ...
Russell K. Hobbie, Bradley J. Roth, 2007
However, the minimum energy for excitation occurs at 1.25 times chronaxie for
the exponential model, as compared to chronaxie for the Lapicque data. For most
neural stimulation applications, one usually sets the pulse duration close to the ...

values are lower, but still high, by 18th-20th month, the chronaxie falls to normal
values. The values of chronaxie for the proximal muscle are higher than those of
the distal muscles. Several variables affect the value of chronaxie, such HS!

Chronaxie. 1. Rheobase Rheobase is the minimum strength (voltage) of stimulus,
which can excite the tissue. The voltage below this cannot excite the tissue,
whatever may be the duration ofthe stimulus. 2. Utilization Time Utilization time is
...

That point is the "chronaxie," and it may be defined as the minimal duration of a
stimulus with an intensity twice the rheobase. The chronaxie is characteristic of
the excitable tissue. Numerous studies have been published (6) on the chronaxie
...

Implantable Neural Prostheses 1: Devices and Applications
In electrical stimulation, the most energy-optimal PW setting is the chronaxie
setting [86, 87]. In a simple stimulation model, where the electrode is modeled as
a pulsed current source, and the tissue is modeled as a lumped parallel
resistance ...

Anatomy and the Problem of Behaviour
It is not unreasonable, therefore, to infer that the same principle is involved in the
excitation of nerve by muscle ; for, in the case of the Rohon-Beard cells, the
muscle cells may impress their own chronaxie upon the muscle- sensory endings
, ...

It is an approximate rectangular hyperbola (xy = k) over the sharply bending
