Human pyramidal to interneuron synapses are mediated by multi-vesicular release and multiple docked vesicles

eLife, 2016
Classic theories link cognitive abilities to synaptic properties and human-specific biophysical features of synapses might contribute to the unparalleled performance of the human cerebral cortex.

Thomas-Fermi theory for atomic nuclei revisited [PDF]

, 2006
The recently developed semiclassical variational Wigner-Kirkwood (VWK) approach is applied to finite nuclei using external potentials and self-consistent mean fields derived from Skyrme interactions and from relativistic mean field theory.

Model-Based Inference of Synaptic Transmission

Frontiers 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 ...

Tsallis' deformation parameter q quantifies the classical-quantum transition [PDF]

, 2008
We investigate the classical limit of a type of semiclassical evolution, the pertinent system representing the interaction between matter and a given field. On using as a quantifier of the ensuing dynamics Tsallis q-entropy, we encounter that it not only

Multiquantal release underlies the distribution of synaptic efficacies in the neocortex

Frontiers 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 ...

MCTP is an ER-resident calcium sensor that stabilizes synaptic transmission and homeostatic plasticity. [PDF]

, 2017
Presynaptic homeostatic plasticity (PHP) controls synaptic transmission in organisms from Drosophila to human and is hypothesized to be relevant to the cause of human disease.

What We Can Learn From Cumulative Numbers of Vesicular Release Events

Frontiers 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

Labor Market Segmentation and Immigrant Competition: A Quantal Response Statistical Equilibrium Analysis

Entropy, 2020
Competition between and within groups of workers takes place in labor markets that are segmented along various, often unobservable dimensions. This paper proposes a measure of the intensity of competition in labor markets on the basis of limited data ...

Enhancing the Study of Quantal Exocytotic Events: Combining Diamond Multi-Electrode Arrays with Amperometric PEak Analysis (APE) an Automated Analysis Code

Biosensors, 2023
MicroGraphited-Diamond-Multi Electrode Arrays (μG-D-MEAs) can be successfully used to reveal, in real time, quantal exocytotic events occurring from many individual neurosecretory cells and/or from many neurons within a network.
