Effect of nonidentical signal phases on signal amplification of two coupled excitable neurons
(ElsevierAmsterdam, 2014-03-15)
In this paper, we study the response of two coupled excitable neurons to external subthreshold periodic signals. We find that the neurons' response to the subthreshold signals can be enhanced when the signal phases are ...
Phase-disorder-induced firing activity in excitable neuronal networks with attractive and repulsive coupling
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
It has been revealed that the network of excitable neurons via attractive coupling can generate spikes under stimuli of subthreshold signals with disordered phases. In this paper, we explore the firing activity induced by ...
Spatially coincident vibrotactile noise improves subthreshold stimulus detection
(Public Library Science, 2017)
Stochastic Resonance (SR) is a phenomenon, mainly present in nonlinear detection systems,
in which the addition of certain amount of noise, called optimal noise, has proven to
enhance detection performance of subthreshold ...
Signal amplification of active rotators with phase-shifted coupling
(SPRINGERNEW YORK, 2012)
In this paper, we study the signal amplification of coupled active rotators with phase-shifted coupling. We find that the system's response to the external subthreshold signal can be significantly affected by each of the ...

A sub-µW intracranial EEG integrated preamplifier
(IEEE, 2022)
This work presents an amplifier targeting the acquisition of intracranial electroencephalography signals with low power consumption, low voltage supply, low noise, and high common-mode rejection ratio (CMRR). A prototype ...
Chlorpyrifos subthreshold exposure induces epithelial-mesenchymal transition in breast cancer cells
(Academic Press Inc Elsevier Science, 2020-12)
Chlorpyrifos (CPF) is one of the most frequently used pesticide in extensive agriculture around the world and can be incorporated by humans and animals with possible consequences on health. The effects of this pesticide ...
Plasma kallikrein enhances platelet aggregation response by subthreshold doses of ADP
(Elsevier B.V., 2017-04-01)
Human plasma kallikrein (huPK) potentiates platelet responses to subthreshold doses of ADP, although huPK itself, does not induce platelet aggregation. In the present investigation, we observe that huPK pretreatment of ...
Current-efficient preamplifier architecture for CMRR sensitive neural recording applications
(IEEE, 2018)
There are neural recording applications in which the amplitude of common-mode interfering signals is several orders of magnitude higher than the amplitude of the signals of interest. This challenging situation for neural ...
