The neuraxis or sometimes neuroaxis [1] is the axis of the central nervous system. It denotes the direction in which the central nervous system lies. During embryological development, the neuraxis is bent by various flexures, contributing to the mature structure of the brain and spinal cord.
Dorsal and ventral: In animals with linear nervous systems, the term dorsal (from the Latin dorsum, meaning "back") is synonymous with superior and the term ventral (from the Latin venter, meaning "belly") is synonymous with inferior. In humans, however, the terminology differs on either side of the midbrain-diencephalic junction.
The neural tube has a longitudinal axis called the neuraxis, from the future brain area at the cranial end, to the conus medullaris of the spinal cord at the caudal end. By the fourth week in the human embryo, at its cranial end, three swellings have formed as primary brain vesicles. [1]
NeurAxis is dedicated to advancing science and leveraging evidence-based medicine to drive the adoption of its IB-Stim™ therapy, which is its proprietary Percutaneous Electrical Nerve Field Stimulation (PENFS) technology, by the medical, scientific, and patient communities.
The resultant patterning along the neuraxis leads to segmentation of the neuroepithelium into progenitor domains (p0, p1 p2, p3 and pMN) for distinct neuron types in the developing spinal cord. On the basis of several studies it is now believed that this model also applies to macroglial cell specification.
Tau can become phosphorylated, meaning that phosphate groups are added to it. This is normal, but in the case of Alzheimer’s, the phosphorylation is abnormal or excessive.
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
Neurexin and neuroligin have been found to be active in synapse maturation and adaptation of synaptic strength. Studies in knockout mice show that the trans-synaptic binding team does not increase the number of synaptic sites, but rather increases the strength of the existing synapses. [12]
