What myelinates axons in the peripheral nervous system? What is the brainstem? What is the hypoglossal nerve? What are Langerhans cells? What is translational neuroscience? What is a presynaptic neuron? What is a bundle of neurons called?
What does the myelin sheath do in a neuron? What are autonomic ganglia? What connects the brain to the peripheral nervous system? What are cholinergic neurons? How do axons and dendrites work together in the brain? What is a bundle of neurons called?
The Latin wordnervusreferred to muscle or sinew, and the English wordnerve, before it came to refer to the bundle of fibers, axons and dendrites that sends and receives messages to the brain, originally appeared in contexts suggesting the idea of muscle: My fate cries out And makes each pet...
The optic nerve is a bundle of more than 1 million axons, or fibers, that carries visual input to the brain from cells in the eye. These cells are part of theretinaand are calledretinal ganglion cells(RGCs). RGC fibers all come together at the very back of the eye in an area called...
Other portions of the spinal cord include white matter made up of nerve fibers (axons) surrounding a vaguely butterfly-shaped core of grey matter. The “body” of the vertebra is the large, round portion of bone in the front side of the spine, while the intervertebral disk is the layer ...
This layer acts as the first line of defense, providing nutritional and physical support to the delicate nerve fibers. Groups of these nerve fibers, or axons, are bundled together into fascicles. Each fascicle is wrapped in a protective layer of connective tissue called the perineurium. ...
Intel has invested large amounts of money on research and development of thought-controlled devices, otherwise known as brain-computer interfaces. Research is underway to determine the best way to harness the power of thought. The internal method requires a craniotomy to implant electrodes in or up...
Retinal ischemia is a common cause of visual impairment and blindness, and is a characteristic feature of various clinical reti- nal disorders such as ischemic optic neuropathies, obstructive arterial and venous retinopathies, carotid occlusive disorders, retinopathy of prematurity, chronic diabetic ...
The corpus callosum is a huge bundle of nerve fibers that bridges the two hemispheres of the brain. Although the corpus callosum...
This specific functional form is shown to originate from theextra-axonal space, and provides estimates of the fiber packing correlationlength for axons in a bundle. Our results offer a metric for the outer axonaldiameter, a promising candidate marker for demyelination in neurodegenerativediseases. ...
