This study optimized conditions for the differentiation of hONPs towards dopaminergic neurons. (scirp.org)
Several neurotrophic factors were detected in the pre-transfected hONPs which have potential roles in the maintenance, survival and proliferation of dopaminergic neurons. (scirp.org)

Signs and symptoms reflect frontal and temporal lobe dysfunction with lower motor neuron-type weakness, muscle atrophy, and fasciculations. (medscape.com)

Such a neuron is called multipolar. (britannica.com)
A cytological smear of human multipolar neurons stained with a mixture of eosin and hematoxylin is illustrated in the photomicrograph presented below. (fsu.edu)

As in the monkey the mirror neuron system is constituted of IPL and a frontal lobe sector formed by the ventral premotor cortex plus the posterior part of the inferior frontal gyrus (IFG) ( Figure 3 ). (scholarpedia.org)

The housekeeping machinery that accomplishes this in many biological processes is made up of the so-called SNARE proteins that form protein bundles across vesicle and plasma membranes, hurling the vesicle or balloon-like structure close to the membrane. (sciencedaily.com)
Regulation of Amyloid ß Oligomer Binding to Neurons and Neurotoxicity by the Prion Protein-mGluR5 Complex. (bvsalud.org)
The prion protein (PrPC) has been suggested to operate as a scaffold/receptor protein in neurons , participating in both physiological and pathological associated events. (bvsalud.org)
PrPC, laminin , and metabotropic glutamate receptor 5 (mGluR5) form a protein complex on the plasma membrane that can trigger signaling pathways involved in neuronal differentiation. (bvsalud.org)

Amyotrophic lateral sclerosis (Lou Gehrig disease) is the most common form of motor neuron disease. (msdmanuals.com)

Degenerative diseases of the human motor system studied at Sheffield include motor neuron disease (MND) and hereditary spastic paraplegia. (yourdictionary.com)

Instead of using just one central source (the cell body) which would be quite inefficient given the large neuronal volume, neurons have adapted a local solution. (mpg.de)
A phosphomutant form of Ascl1 shows substantially enhanced neuronal induction activity in Xenopus embryos," the authors wrote. (genengnews.com)

Radical Idea croscopic method to view subsets of By the mid-1970s, Björklund had switched neurons. (lu.se)

Finally, data presented in Chapter Four demonstrate that the effect of food restriction on BSR is contingent on the placement of the electrode amongst a functionally heterogeneous population of directly-activated neurons. (concordia.ca)

The process also worked simultaneously in reverse as well from Zurich to Padova thus the artificial and biological neurons were able to communicate bidirectionally and in real time. (worldhealth.net)

ALS, also known as Lou Gehrig disease, is the most common neurodegenerative disease of adult onset involving the motor neuron system. (medscape.com)

Our data suggest that OD shifts observed in the binocular visual cortex of adult mice may at least partially reflect plasticity of eye-specific inputs onto dLGN neurons. (nature.com)
In an adult they are usually dormant, and spring to action only rarely and at specific locations, for example to form normal memory episodes. (eurekalert.org)

A peptide mimicking the binding site of laminin onto PrPC (Ln-Î³1) binds to PrPC and induces intracellular Ca2+ increase in neurons via the complex PrPC-mGluR5. (bvsalud.org)

Using our approach, we find preliminary evidence that subvisible Aβ aggregates are detected at specific subcellular regions and that neurons drive the formation of specific Aβ aggregate conformations. (bris.ac.uk)
We find this environment inside neurons, specifically in subcellular compartments called endosomes/lysosomes. (lu.se)

The cilia have a length of up to 100 micrometres and with the cilia from other dendrites form a meshwork in the olfactory mucus. (wikipedia.org)
High-resolution imaging and 3D computer modeling show that the dendrites of neurons weave through space in a way that balances their need to connect to other neurons with the costs of doing so. (sciencedaily.com)
With the help of UO post-doctoral researcher Saba Moslehi, doctoral students Julian H. Smith and Conor Rowland turned to 3D modeling to explore what happens when they manipulated the dendrites of more than 1,600 neurons into unnatural forms, straightening them or curling them up. (sciencedaily.com)

Patients with motor neuron disease (MND) are generally free of cognitive impairment, but evidence is growing to support an association between MND and frontal lobe or frontotemporal dementia (FTD). (medscape.com)
Worldwide, frontotemporal lobe dementia with motor neuron disease (FTD/MND) is a sporadic condition with an unknown etiology. (medscape.com)

Methods to isolate and expand the hONPs which form neurospheres in vitro have been developed in our laboratory. (scirp.org)

How neurons assemble meaningful images from individual dots of light and then drive appropriate behavior is an area of intense research. (mpg.de)
Unlike building a straight runway so a pilot can land efficiently, our electrodes will need to act like a weaving runway so that the neurons can connect without changing their behavior. (sciencedaily.com)

New research could help find a solution to slowing down the progression of motor neuron disease. (neurosciencenews.com)

We have shown for the first time the protective effect of deleting Nav1.1 in excitatory neurons on the pathology of Dravet syndrome," says Yamakawa. (medicalxpress.com)
