Advanced Science, EarlyView.The human brain's imagination, which enables autonomous driving hazard avoidance by completing missing visual information, relies on Gaussian‐stochastic neuron. We report the altermagnetic RuO2 spintronic neurons integrating field‐free switching and intrinsic Gaussian stochasticity, building an all‐spin ANN for high‐quality image repairing and high ...

Considerations for determining the time course of post-activation potentiation
Applied Physiology, Nutrition and Metabolism, 2015 We sought to determine the efficacy of using a continuous time course trial to assess the temporal profile of post-activation potentiation and to determine the time course of potentiation of discrete jump squat kinetic and kinematic variables. Eight physically trained men performed jump squats before and 4, 8, and 12 min after a 5-repetition maximum ...

Mechanomyographic determination of post-activation potentiation in myopathies
Clinical Neurophysiology, 2006There is a need to provide an index of muscle contractility in evaluating myopathies especially in the clinical setting. This study was conducted to investigate if the mechanomyogram post-activation potentiation (MMG-PAP) can be used as an index of muscle contractile force potentiation (force-PAP), if it differs between normal and myopathic muscles ...

Validation of jump squats as a practical measure of post-activation potentiation
Applied Physiology, Nutrition, and Metabolism, 2013 To determine if post-activation potentiation (PAP) can augment sports performance, it is pertinent that researchers be confident that any enhancement in performance is attributable to the PAP phenomenon. However, obtaining mechanistic measures of PAP in the daily training environment of highly trained athletes is impractical.

Effect of intensity and duration of conditioning protocol on post‐activation potentiation and changes in H‐reflex [PDF]
European Journal of Sport Science, 2011 [Abstract]: The force enhancement of muscle twitch contraction after a maximal voluntary contraction (MVC) has been defined as post-activation potentiation. However, the effects of post-activation potentiation on ballistic movements have not been studied

The surface electromyographic (EMG) activity of the biceps brachii during weak elbow flexion reportedly increases immediately after strong elbow flexion, even during the exertion of a given force. This phenomenon is called post-contraction potentiation (EMG-PCP). However, the effects of test contraction intensity (TCI) on EMG-PCP remain unclear.

Post‐activation potentiation: The neural effects of post—activation depression
Muscle & Nerve, 2014ABSTRACTIntroduction: Our knowledge of the neurophysiology of post‐activation potentiation (PAP) is limited. The purpose of this study was to examine the effect of PAP on twitch torque and H‐reflex amplitude after a 10‐s maximal voluntary contraction (MVC).

Post-activation potentiation and the kindling phenomenon
Electroencephalography and Clinical Neurophysiology, 1975Potentials evoked in the hippocampus and preoptic region of rats by single biphasic pulses applied to the amygdala were compared during recruiting, after post-tetanic potentiation (PTP) and after amygdaloid kindling. The same components were enhanced temporarily by recruiting and PTP as were enhanced permanently by kindling.

The response of muscle to volitional or electrically induced stimuli is affected by its contractile history. Fatigue is the most obvious effect of contractile history reflected by the inability of a muscle to generate an expected level of force. However, fatigue can coexist with post-activation potentiation (PAP), which serves to improve muscular ...
