The small intestine is covered by a network of coupled oscillators, the interstitial cells of Cajal (ICC). These oscillators synchronize to generate rhythmic phase waves of contraction. At points of low coupling, oscillations desynchronise, frequency ste
Nerve xenografts to apportion the role of axon and Schwann cell in myelinated fiber absence in hereditary sensory neuropathy, type II Dyck PJ, Lais AC, Sparks MF, Oviatt KF, Hexum LA, SteinmullerD (1979) Nerve xenografts to apportion the role of axon and Schwann cell in myelinated fiber...
Placental dysfunction may increase the offspring’s later-life disease risk. The objective of this systematic review was to describe associations between pathological placental changes and neuropsychological outcomes in children after the neonatal period. The inclusion criteria were human studies; original re...
The expression of CB1Rs has been demonstrated in the axon terminals of the glutamatergic cortico-striatal neurons, the glutamatergic neurons projecting to subthalamic nucleus (STN), globus pallidus internus (GPi)/substantia nigra pars reticulata (SNpr), and the GABAergic neurons innervating GPi/SNpr ...
The spatial organization of glucose metabolism machineries across axon.A. Upper panel: Heat map description of the degree of energy consumption by each axonal activity within three axonal subdomains. Bottom panel: the intensity of each feature/parameter of glucose metabolism machineries within three axon...
The effect of varying membrane capacitance, conductance, and rate constants on the properties of the nerve impulse is considered in terms of the degree of regeneration in the Hodgkin-Huxley model for the squid giant axon. It is shown through computer simulation that reducing regeneration generally ...
The heart of each neuron is called the soma - a single thin cable-like fiber known as the axon that sticks out of the soma carries nerve signals away from the neuron, while many shorter branches called dendrites that project from the other end of the soma carry nerve signals to the ...
Nerve cells fire electric impulses. When an electrical nerve signal from one nerve cell arrives at the synapse, it triggers the release of chemicals called neurotransmitters. Those chemicals travel across the synapse and attach or "bind" to proteins on the dendritic spine that are called receptors...
When the action potential hits the end of one nerve, the signal must move across the barrier to another cell at the synapse. At the end of the axon, the action potential triggers the release of neurotransmitters such as dopamine and adrenaline. The neurotransmitters float across the tiny junct...
Via the axon, impulses are sent to other neurons. The axon's end is divided into branches which form synapses with other neurons. The synapse is a specialized interface between two nerve cells. The synapse consists of a cleft between a presynaptic and postsynaptic neuron. At the end of the...
