Weakly quadratent rings

open access: yesJournal of Taibah University for Science, 2019
We completely characterize up to an isomorphism those rings whose elements satisfy the equations $ x^4=x $ or $ x^4=-x $ . Specifically, it is proved that a ring is weakly quadratent if, and only if, it is isomorphic to either K, $ \mathbb {Z}_3 ...

The origin of extracellular fields and currents — EEG, ECoG, LFP and spikes

open access: yesNature Reviews Neuroscience, 2012
Neuronal activity in the brain gives rise to transmembrane currents that can be measured in the extracellular medium. Although the major contributor of the extracellular signal is the synaptic transmembrane current, other sources — including Na+ and Ca2+
