Molecular model of postsynaptic potential. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1975
A molecular model of the excitatory postsynaptic membrane is given in terms of two biochemical cycles intimately associated: an acetylcholine cycle and a calcium cycle.

Rectified Linear Postsynaptic Potential Function for Backpropagation in Deep Spiking Neural Networks

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2021
Spiking neural networks (SNNs) use spatiotemporal spike patterns to represent and transmit information, which are not only biologically realistic but also suitable for ultralow-power event-driven neuromorphic implementation. Just like other deep learning

Imperfect space clamp permits electrotonic interactions between inhibitory and excitatory synaptic conductances, distorting voltage clamp recordings. [PDF]

open access: yesPLoS ONE, 2011
The voltage clamp technique is frequently used to examine the strength and composition of synaptic input to neurons. Even accounting for imperfect voltage control of the entire cell membrane ("space clamp"), it is often assumed that currents measured at ...

Inference on the effect of non homogeneous inputs in Ornstein-Uhlenbeck neuronal modeling

open access: yesMathematical Biosciences and Engineering, 2020
A non-homogeneous Ornstein-Uhlembeck (OU) diffusion process is considered as a model for the membrane potential activity of a single neuron. We assume that, in the absence of stimuli, the neuron activity is described via a time-homogeneous process with ...

AMPA Receptor Trafficking for Postsynaptic Potentiation [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2018
Long-term potentiation (LTP) of excitatory synaptic strength, which has long been considered a synaptic correlate for learning and memory, requires a fast recruitment of additional α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptors (AMPARs) to the postsynaptic sites.

Pre & postsynaptic tuning of action potential timing by spontaneous GABAergic activity. [PDF]

open access: yesPLoS ONE, 2011
Frequency and timing of action potential discharge are key elements for coding and transfer of information between neurons. The nature and location of the synaptic contacts, the biophysical parameters of the receptor-operated channels and their kinetics ...

Distribution of densin in neurons. [PDF]

open access: yesPLoS ONE, 2018
Densin is a scaffold protein known to associate with key elements of neuronal signaling. The present study examines the distribution of densin at the ultrastructural level in order to reveal potential sites that can support specific interactions of ...

Influence of Mpv17 on Hair-Cell Mitochondrial Homeostasis, Synapse Integrity, and Vulnerability to Damage in the Zebrafish Lateral Line

open access: yesFrontiers in Cellular Neuroscience, 2021
Noise exposure is particularly stressful to hair-cell mitochondria, which must produce enough energy to meet high metabolic demands as well as regulate local intracellular Ca2+ concentrations.

Analysis of the slow excitatory postsynaptic potential in bullfrog sympathetic ganglion cells.

open access: yesThe Japanese Journal of Physiology, 1976
The ionic mechanism of the slow excitatory postsynaptic potential (slow EPSP), i.e. the muscarinic action of acetylcholine (ACh), was studied either by stimulating preganglionic nerves or by applying ACh in curarized sympathetic ganglion cells of ...
