Effects of Tetrodotoxin on the Mammalian Cardiovascular System

open access: yesMarine Drugs, 2010
The human genome encodes nine functional voltage-gated Na+ channels. Three of them, namely Nav1.5, Nav1.8, and Nav1.9, are resistant to nanomolar concentrations of tetrodotoxin (TTX; IC50 ≥ 1 μM).

The enteric nervous system : new developments and emerging concepts [PDF]

open access: yes, 2011
The enteric nervous system (ENS) is an integrative neuronal network, organized in two ganglionated plexuses, myenteric and submucosal, composed of neurons and enteric glial cells, controlling the activity of the smooth muscle of the gut, mucosal ...

Daily changes in sleep stages and associated cardiovascular parameters during pregnancy: using a wearable device

open access: yesFrontiers in Global Women's Health
ObjectiveGrowing evidence links sleep disturbances with gestational hypertension and/or preeclampsia. Most studies rely on self-reported surveys that cannot capture sleep stages as objective indicators of cardiovascular health.

Ageing and the autonomic nervous system

open access: yes, 2003
The vertebrate nervous system is divided into central (CNS) and peripheral (PNS) components. In turn, the PNS is divided into the autonomic (ANS) and enteric (ENS) nervous systems.

Dysfunctional HCN ion channels in neurological diseases

open access: yesFrontiers in Cellular Neuroscience, 2015
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed as four different isoforms (HCN1-4) in the heart and in the central and peripheral nervous systems.

Nerve conduction models in myelinated and unmyelinated nerves based on three-dimensional electrostatic interaction

open access: yesNeural Regeneration Research, 2018
Until now, nerve conduction has been described on the basis of equivalent circuit model and cable theory, both of which supposed closed electric circuits spreading inside and outside the axoplasm.

Synapse-Specific Regulation Revealed at Single Synapses Is Concealed When Recording Multiple Synapses

open access: yesFrontiers in Cellular Neuroscience, 2017
Synaptic transmission and its activity-dependent modulation, known as synaptic plasticity, are fundamental processes in nervous system function. Neurons may receive thousands of synaptic contacts, but synaptic regulation may occur only at individual or ...
