Martin A. Samuels (June 24, 1945 – June 6, 2023) was an American physician, neurologist, and medical educator. [1] He wrote and spoke on the relationships between neurology and the rest of medicine and linked the nervous system with cardiac function.
[3] Martin A. Samuels, MD, elaborates further on still another process of death, stating that with the release of adrenaline and an increased heart rate, sometimes catecholamines, stress hormones, will build up, leading to calcium channels opening and remaining open, resulting in an overflow of calcium into the system, killing off cells.

The soliton model is an alternative to the Hodgkin–Huxley model that claims to explain how action potentials are initiated and conducted in the form of certain kinds of solitary sound (or density) pulses that can be modeled as solitons along axons, based on a thermodynamic theory of nerve pulse propagation.
The biomedical model of medicine care is the medical model used in most Western healthcare settings, and is built from the perception that a state of health is defined purely in the absence of illness. [1]: 24, 26 The biomedical model contrasts with sociological theories of care. [1]: 1 [2]
In biophysics and cognitive science, the free energy principle is a mathematical principle describing a formal account of the representational capacities of physical systems: that is, why things that exist look as if they track properties of the systems to which they are coupled. [2]
The resulting model had more than 140,000 neurons with over 50 million synapses. [21] From the model, research expect to identify how the brain creates new connections for functions such as vision, creating digital twin equivalents to track how segments of the neuron connection map interact to external signals, including the nervous system.
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
Models that describe health behavior change can be distinguished in terms of the assumption whether they are continuum-based or stage-based. [7] A continuum (mediator) model claims that change is a continuous process that leads from lack of motivation via action readiness either to successful change or final disengagement.
