Molecular model of postsynaptic potential. [PDF]

open access: greenProceedings 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. The acetylcholine controls the Na ionophores while calcium ions control the tk ionophore.

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 ...

Postsynaptic neuronal activity promotes regeneration of retinal axons

open access: yesCell Reports, 2023
Summary: The wiring of visual circuits requires that retinal neurons functionally connect to specific brain targets, a process that involves activity-dependent signaling between retinal axons and their postsynaptic targets.

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 ...

NMDA Currents Modulate the Synaptic Input–Output Functions of Neurons in the Dorsal Nucleus of the Lateral Lemniscus in Mongolian Gerbils [PDF]

open access: yes, 2011
Neurons in the dorsal nucleus of the lateral lemniscus (DNLL) receive excitatory and inhibitory inputs from the superior olivary complex (SOC) and convey GABAergic inhibition to the contralateral DNLL and the inferior colliculi.

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 ...
