Resistance to consistent shocks as a function of training schedules of interspersed shocks
An earlier study had developed a response that persisted in spite of shocks-no-food for 2 months. The present study successfully replicated the inextinguishable character of the response (Experiment 1) and, as one of its determinants, further investigated three schedules of shocks interspersed among rewards: (1) fixed ratio — constant frequency, (2) random ratio — constant frequency, and (3) gradual progression. Tests with consistent shocks showed: (1)no differences between fixed and random ratio and (2) a greater suppression in gradual progression, suggesting schedule as subsidiary to frequency of shocks.
We measured the change of the terahertz-frequency dielectric properties in collagen hydrated in saline spanning hypo-normal, normal and hyper-normal physiological conditions, during a 24-hour dehydration period in-vitro.
