Modeling Fault Propagation Paths in Power Systems: A New Framework Based on Event SNP Systems With Neurotransmitter Concentration [PDF]

, 2019
To reveal fault propagation paths is one of the most critical studies for the analysis of power system security; however, it is rather dif cult. This paper proposes a new framework for the fault propagation path modeling method of power systems based ...

Long-Lived States of Methylene Protons in Achiral Molecules [PDF]

arXiv, 2022
It is shown that long-lived states (LLS) involving pairs of methylene protons in nuclear magnetic resonance (NMR) can be readily excited in common molecules that contain two or more neighboring CH$_2$ groups. Accessing such LLS does not require any isotopic enrichment, nor does it require any stereogenic centers to lift the chemical equivalence of CH ...

A Novel Approach to Implementing Artificial Thalamic Neurons with Ferroelectric Transistors

Advanced Functional Materials, EarlyView.
Artificial neurons created using CMOS technology often require a large number of transistors and capacitors. This study introduces an artificial thalamic neuron that employs only five CMOS compatible ferroelectric transistors. The manufactured thalamic neuron demonstrates leaky integrate‐and‐fire‐or‐burst (LIFB) functionalities, featuring self ...

cAMP Response Element-Binding Protein (CREB): A Possible Signaling Molecule Link in the Pathophysiology of Schizophrenia

Frontiers in Molecular Neuroscience, 2018
Dopamine is a brain neurotransmitter involved in the pathology of schizophrenia. The dopamine hypothesis states that, in schizophrenia, dopaminergic signal transduction is hyperactive.

A Mathematical model for Astrocytes mediated LTP at Single Hippocampal Synapses

, 2012
Many contemporary studies have shown that astrocytes play a significant role in modulating both short and long form of synaptic plasticity. There are very few experimental models which elucidate the role of astrocyte over Long-term Potentiation (LTP ...

A receptor-based analysis of local ecosystems in the human brain. [PDF]

, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

LKB1 Regulates Mitochondria-Dependent Presynaptic Calcium Clearance and Neurotransmitter Release Properties at Excitatory Synapses along Cortical Axons

PLoS Biology, 2016
Individual synapses vary significantly in their neurotransmitter release properties, which underlie complex information processing in neural circuits. Presynaptic Ca2+ homeostasis plays a critical role in specifying neurotransmitter release properties ...

Neurotransmitter release [PDF]

FEBS Letters, 1990
Axon terminals release more than one physiologically active substance. Synaptic messengers may be stored in two different types of vesicles. Small electron‐lucent vesicles mainly store classical low molecular weight transmitter substances and the larger electron‐dense granules store and release proteins and peptides.

Activity-dependent stochastic resonance in recurrent neuronal networks [PDF]

, 2008
We use a biophysical model of a local neuronal circuit to study the implications of synaptic plasticity for the detection of weak sensory stimuli. Networks with fast plastic coupling show behavior consistent with stochastic resonance. Addition of an additional slow coupling that accounts for the asynchronous release of neurotransmitter results in ...
