Degeneracy in hippocampal physiology and plasticity

RK Rathour, R Narayanan - Hippocampus, 2019 - Wiley Online Library
Degeneracy, defined as the ability of structurally disparate elements to perform analogous
function, has largely been assessed from the perspective of maintaining robustness of …

How multiple conductances determine electrophysiological properties in a multicompartment model

AL Taylor, JM Goaillard, E Marder - Journal of Neuroscience, 2009 - Soc Neuroscience
Most neurons have large numbers of voltage-and time-dependent currents that contribute to
their electrical firing patterns. Because these currents are nonlinear, it can be difficult to …

Neuronal morphology enhances robustness to perturbations of channel densities

Y Zang, E Marder - Proceedings of the National Academy of …, 2023 - National Acad Sciences
Biological neurons show significant cell-to-cell variability but have the striking ability to

Drosophila voltage-gated sodium channels are only expressed in active neurons and are localized to distal axonal initial segment-like domains

TA Ravenscroft, J Janssens, PT Lee… - Journal of …, 2020 - Soc Neuroscience
In multipolar vertebrate neurons, action potentials (APs) initiate close to the soma, at the
axonal initial segment. Invertebrate neurons are typically unipolar with dendrites integrating …

Signal propagation in Drosophila central neurons

NW Gouwens, RI Wilson - Journal of Neuroscience, 2009 - Soc Neuroscience
