In this study, we want to evaluate the relative importance of three factors on site-independence of somatic EPSP amplitude: (1) "passive normalization" in non-uniform passive models, (2) voltage-gated channels

All living organisms use active and passive proton transport mechanisms to control intracellular pH and proton gradients across cell membranes. Passive mechanisms, mediated by ion channels, let protons flow along their electrochemical gradient in response to specific signals. In animal cells, two major ...
Potassium (KC) channels are largely responsible for shaping the electrical behavior of cell membranes. KC channel currents set the resting membrane potential, control action potential duration, control the rate of action potential firing, control the spr
The channels for K+ and Na+ are represented using variable voltage-time resistances, and the passive gates for Na+, K+, and Cl− are given by a leakage channel with resistance Rl (that is, the Thevenin's equivalent circuit of the passive channels). The function of the voltage clamp ...
but it could also be possible that expression of both fragments induce the functional expression of an otherwise not detected endogenous voltage-gated channel. However, this cannot be due to only one of the fragments, since we did not observe either outward or tail currents upon injection of any...

The combination of in vitro multi-electrode arrays (MEAs) and the neuronal differentiation of stem cells offers the capability to study human neuronal networks from patient or engineered human cell lines. Here, we use MEA-based assays to probe synaptic f
9.3.1.2.1 DAC Register Synchronous and Asynchronous Updates The update mode for each DAC channel is determined by the status of its corresponding SYNC-EN bit. In asynchronous mode, a write to the DAC data register results in an immediate update of the DAC active register and DAC output on ...
