Spike transmission between electrically coupled sensory neurons is improved by filter properties.
(IEEE, 2020)
In the nervous system, neurons are organized in networks by way of connections constituted by chemical and electrical synapses. We use biological and mathematical models to study electrical synaptic communication and its ...
Encoding sound in the cochlea: from receptor potential to afferent discharge
(Wiley Blackwell Publishing, Inc, 2021-05)
Ribbon-class synapses in the ear achieve analog to digital transformation of a continuously graded membrane potential to all-or-none spikes. In mammals, several auditory nerve fibres (ANFs) carry information from each inner ...
The impact of micropollutants on native algae and cyanobacteria communities in ecological filters during drinking water treatment
(2022-05-20)
An attractive alternative for drinking water production is ecological filtration. Previous studies have reported high removal levels of pharmaceutical and personal care products (PPCPs) by this technology. Algae and ...
Removal of groundwater arsenic using a household filter with iron spikes and stainless steel
(Journal of Environmental Management, 2016)
Effects of spike-triggered negative feedback on receptive-field properties
(Springer, 2015-04-21)
Sensory neurons are often described in terms of a receptive field, that is, a linear kernel through which stimuli are filtered before they are further processed. If information transmission is assumed to proceed in a ...
Feasibility of using solid sampling graphite furnace atomic absorption spectrometry for preparation of spiked filter papers with Cu and Zn as standards for direct solid analysis
(SPRINGER HEIDELBERG, 2008)
An approach was developed for the preparation of cryogenic ground spiked filter papers with Cu and Zn for use as synthetic calibrating standards for direct solid microanalysis. Solid sampling graphite furnace atomic ...
Competition between Persistent Na+ and Muscarine-Sensitive K+ Currents Shapes Perithreshold Resonance and Spike Tuning in CA1 Pyramidal Neurons
(2017)
Neurons from many brain regions display intrinsic subthreshold theta-resonance, responding preferentially to theta-frequency oscillatory stimuli. Resonance may contribute to selective communication among neurons and to ...
Occurrence of PPCPs in a Brazilian water reservoir and their removal efficiency by ecological filtration
(2019-07-01)
The presence of PPCPs (Pharmaceuticals and Personal Care Products) in water sources and drinking water has concerned researchers in recent times. This study was carried out to evaluate the occurrence of 6 PPCPs (namely ...
