Amitriptyline Decreases GABAergic Transmission in Basal Forebrain Neurons Using an Optogenetic Model of Aging

open access: yesFrontiers in Aging Neuroscience, 2021
The antidepressant drug amitriptyline is used in the treatment of clinical depression and a variety of neurological conditions such as anxiety, neuropathic pain disorders and migraine.

Unveiling the Synaptic Function and Structure Using Paired Recordings From Synaptically Coupled Neurons

open access: yesFrontiers in Synaptic Neuroscience, 2020
Synaptic transmission between neurons is the basic mechanism for information processing in cortical microcircuits. To date, paired recording from synaptically coupled neurons is the most widely used method which allows a detailed functional ...

Estimation of cumulative amplitude distributions of miniature postsynaptic currents allows characterising their multimodality, quantal size and variability

open access: yesScientific Reports, 2023
A miniature postsynaptic current (mPSC) is a small, rare, and highly variable spontaneous synaptic event that is generally caused by the spontaneous release of single vesicles.

Quantal-Classical Duality and the Semiclassical Trace Formula [PDF]

open access: yes, 1997
We consider Hamiltonian systems which can be described both classically and quantum mechanically. Trace formulas establish links between the energy spectra of the quantum description and the spectrum of actions of periodic orbits in the classical ...

Model-Based Inference of Synaptic Transmission

open access: yesFrontiers in Synaptic Neuroscience, 2019
Synaptic computation is believed to underlie many forms of animal behavior. A correct identification of synaptic transmission properties is thus crucial for a better understanding of how the brain processes information, stores memories and learns ...

Multiquantal release underlies the distribution of synaptic efficacies in the neocortex

open access: yesFrontiers in Computational Neuroscience, 2009
Inter-pyramidal synaptic connections are characterized by a wide range of EPSP amplitudes. Although repeatedly observed at different brain regions and across layers, little is known about the synaptic characteristics that contribute to this wide range ...

What We Can Learn From Cumulative Numbers of Vesicular Release Events

open access: yesFrontiers in Cellular Neuroscience, 2019
Following action potential invasion in presynaptic terminals, synaptic vesicles are released in a stochastic manner at release sites (docking sites). Since neurotransmission occurs at frequencies up to 1 kHz, the mechanisms underlying consecutive vesicle

Estimating the Readily-Releasable Vesicle Pool Size at Synaptic Connections in the Neocortex

open access: yesFrontiers in Synaptic Neuroscience, 2019
Previous studies based on the ‘Quantal Model’ for synaptic transmission suggest that neurotransmitter release is mediated by a single release site at individual synaptic contacts in the neocortex.

Quantal analysis based on density estimation

open access: yesJournal of Neuroscience Methods, 2003
When direct measurements of the quantal parameters for a synapse cannot be made, these parameters can be extracted from an analysis of the fluctuations in the evoked response at that synapse. In this article, a decision tree is described in which the ability of the data to match simple models of quantal transmission is rigorously compared with its ...

An explanation of anomalous behavior in models of political participation [PDF]

open access: yes, 2005
This paper characterizes behavior with “noisy” decision making for models of political interaction characterized by simultaneous binary decisions. Applications include: voting participation games, candidate entry, the volunteer's dilemma, and collective ...
