neu·ron

 (no͝or′ŏn′, nyo͝or′-)
n.
1. Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves in vertebrates, consisting of a nucleated cell body with one or more dendrites and a single axon.
2. A similar impulse-conducting cell in invertebrates. In both senses also called nerve cell.

[Greek, sinew, string, nerve; see (s)neəu- in Indo-European roots.]

neu′ro·nal·ly adv.

neu•ron

(ˈnʊər ɒn, ˈnyʊər-)

n.
a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.
Also called nerve cell. Also, esp. Brit.,neu•rone (-oʊn)

The mutated HTT produces the mutant HTT protein, leading to profound neuronal loss and progressive deterioration of motor, psychiatric, and cognitive abilities.
SINGAPORE, June 18, 2019 -- How dormant neural stem cells in fruit flies are activated and generate new neurons is described in a new research study that may someday help people with brain injury or neuronal loss, if similar mechanisms apply in humans.
Cytokine levels also did not correlate with neuronal loss and Alzheimer-type neurodegeneration markers amyloid [beta] and tau.
It causes progressive deterioration of [beta]-cell function and also insulin resistance.[1] The variables such as the sex, age at the onset of disease, duration of the disease, age of patients influence blood glucose level directly, and HbA1C indirectly.[2] Degenerative changes are accelerated by poor glycemic control and age-related pathology with duration of disease.[3,4] Patients with diabetes mellitus are suffering with subclinical both sensory and motor neuronal loss due to consequences of hyperglycemic status.
This results in PrP that becomes more susceptible to transformation into an abnormal misfolded form, triggering a selective loss of neurons in the limbic thalamus and corticolimbic regions.[20] The highly selective neuronal loss is partly due to the binding of FFI toxic PrP or proteinase K-resistant prion protein (PrPres) to specific receptors, such as the limbic system-associated membrane protein (LAMP) receptor on thalamolimbic neurons.[21]
Conditions in children that lead to neuronal injury, neuronal loss or poor functional outcome have been associated with decreased NAA levels.
(3) Reduction of NAA is indicative of neuronal loss. Spectroscopy ratios show that there is more severe cerebellar involvement, which corresponds with pathological data.

The present study revealed that the injection of A[beta] and viral vectors with the SNCA gene into the brain caused an accumulation of [alpha]-syn, neuronal loss, and lowered neuronal activity in the hippocampus, suggesting that this method can induce a useful model of DLB.
