How regular is neuronal activity?

چکیده
We propose and investigate two information-based measures of statistical dispersion of neuronal firing: the entropy-based dispersion and Fisher information-based dispersion. The measures are compared with the standard deviation. Although the standard deviation is used routinely, we show, that it is not well suited to quantify some aspects of dispersion that are often expected intuitively, such as the degree of randomness. The proposed dispersion measures are not entirely independent, although each describes the firing regularity from a different point of view.

How to Exercise During Coronavirus Quarantine?
The COVID-19 pandemic caused stress and anxiety in many people that can be reduced by regular physical activity. Regular physical exercise is essential for health. In the absence of COVID-19 symptoms, no limitation in physical activity is recommended. However, parameters such as frequency, intensity, type, and time need to be considered to prescribe the program and obtain the best results. Con...
متن کاملEffects of Dorema ammoniacum Gum on Neuronal Epileptiform Activity-Induced by Pentylenetetrazole
Epilepsy is a chronic neurological disease which disrupts the neuronal electrical activity. One-third of patients are resistant to treatment with available antiepileptic agents. The use of herbal medicine for treating several diseases including epilepsy is on the rise. Therefore, further investigation is required to verify the safety and effectiveness of Phytomedicine in treating diseases. The ...

متن کاملStress-related effects on neuronal morphology and choline acetyltransferase activity in the hippocampus
The effects of semi-chronic stress on neuronal morphology and choline acetyltransferase were studied by injecting rats with dexamethasone. It was found that in the dexamethasone-treated rats the choline acetyltransferase activity had increased in the area where the fibers from the perforant pathway synapse with the granular cell layer of the dentate gyrus and also where the mossy fibers of the ...
