Potassium balance and glaucoma

Retinal ganglion cells (RGCs) make up the optic nerve. When RGCs degenerate due to elevated intraocular pressure caused by glaucoma, vision is lost.

Novel therapy administered after TBI prevents brain damage

An experimental treatment given to mice after a traumatic brain injury (TBI) reduced damage almost to the levels of mice that never had a TBI, researchers at UT Health San Antonio reported. The study was published July 4 ...

'Crosstalk' between genes promotes brain inflammation in Alzheimer's

A new study by scientists at Massachusetts General Hospital (MGH) offers clues about how to prevent inflammation of brain tissue, which promotes Alzheimer's disease (AD). The findings of this study online now and appearing ...

Machine learning about glaucoma

Untreated glaucoma is a major cause of sight loss. There are several forms and they are all essentially caused by damage to the optic nerve due to increased pressure within the eye. A collaboration between scientists in Algeria ...

An 'EpiPen' for spinal cord injuries

An injection of nanoparticles can prevent the body's immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis.

Neuroscience

First step to induce self-repair in the central nervous system

Damaged peripheral nerves can regenerate after an injury, for example, following a forearm fracture. Axons, the long projections of neurons that transmit stimuli or signals to other cells, are affected in the case of injury ...

How a popular antidepressant drug could rewire the brain

Prozac, the trade name for the drug fluoxetine, was introduced to the U.S. market for the treatment of depression in 1988. Thirty years later, scientists still don't know exactly how the medication exerts its mood-lifting ...

Nerve

A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is technically inaccurate since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
