Understanding electrical and chemical transmission in the brain

open access: yesFrontiers in Cellular Neuroscience
The histochemical Falck-Hillarp method for the localization of dopamine (DA), noradrenaline (NA) and serotonin in the central nervous system (CNS) of rodents was introduced in the 1960s. It supported the existence of chemical neurotransmission in the CNS.

Investigations into potential extrasynaptic communication between the dopaminergic and nitrergic systems

open access: yesFrontiers in Physiology, 2012
Nitric oxide is unconstrained by cell membranes and can therefore act along a broad distance as a volume transmitter. Spillover of nitric oxide between neurons may have a major impact on central nervous system diseases and particularly on ...

The satiety signaling neuropeptide perisulfakinin inhibits the activity of central neurons promoting general activity

open access: yesFrontiers in Cellular Neuroscience, 2007
The metabolic state is one of the determinants of the general activity level. Satiety is related to resting or sleep whereas hunger correlates to wakefulness and activity.

Multi-objective optimization model of transmission error of nonlinear dynamic load of double helical gears

open access: yesNonlinear Engineering, 2023
In order to address the impact of reduced transmission stability and reliability caused by volume reduction on the quality of gear transmission, this article proposes a multi-objective optimization model for nonlinear dynamic load transmission errors of ...

Tuning synaptic transmission in the hippocampus by stress: The CRH system

open access: yesFrontiers in Cellular Neuroscience, 2012
To enhance survival, an organism needs to remember--and learn from--threatening or stressful events. This fact necessitates the presence of mechanisms by which stress can influence synaptic transmission in brain regions, such as hippocampus, that ...

Diverse in- and output polarities and high complexity of local synaptic and non-synaptic signalling within a chemically defined class of peptidergic Drosophila neurons

open access: yesFrontiers in Neural Circuits, 2013
Peptidergic neurons are not easily integrated into current connectomics concepts, since their peptide messages can be distributed via non-synaptic paracrine signalling or volume transmission.

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

A geographic routing protocol based on trunk line in VANETs

open access: yesDigital Communications and Networks, 2021
A Trunk Line Based Geographic Routing(TLBGR) protocol in Vehicular Ad-hoc Networks (VANETs) is proposed in this paper to solve the problem of data acquisition in the traditional trunk coordinated control system.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Extrasynaptic Neurotransmission Mediated by Exocytosis and Diffusive Release of Transmitter Substances

open access: yesFrontiers in Synaptic Neuroscience, 2018
This review article deals with the mechanisms of extrasynaptic release of transmitter substances, namely the release from the soma, axon and dendrites in the absence of postsynaptic counterparts.
