Treating brain diseases now possible

Neurological diseases of the brain such as dementia, autism and schizophrenia are now a growing social problem. Nevertheless, studies on their definitive cause are still insufficient. Recently, a POSTECH research team has ...

Stable connections between nerve cells are the basis of memory

Memories are part of our lives, the good and the bad. Through our senses, experiences reach our brain where networks of nerve cells encode them into a memory. It was previously unclear why only certain nerve cells join together ...

How SARS-CoV-2 reaches the brain

Using post-mortem tissue samples, a team of researchers from Charité - Universitätsmedizin Berlin have studied the mechanisms by which the novel coronavirus can reach the brains of patients with COVID-19, and how the immune ...

Brain's 'speedometer' could help solve part of dementia puzzle

Nearly one million people in the UK have dementia. People living with the most common form, Alzheimer's disease, can experience difficulties working out where they are, meaning they often get lost even in familiar environments. ...

Gut immune cells may help send multiple sclerosis into remission

An international research team led by UCSF scientists has shown, for the first time, that gut immune cells travel to the brain during multiple sclerosis (MS) flare-ups in patients. These gut cells seem to be playing a protective ...

Neuron

A neuron (pronounced /ˈnjʊərɒn/ N(Y)OOR-on, also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signalling. Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves. A number of specialized types of neurons exist: sensory neurons respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. Motor neurons receive signals from the brain and spinal cord and cause muscle contractions and affect glands. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. Neurons respond to stimuli, and communicate the presence of stimuli to the central nervous system, which processes that information and sends responses to other parts of the body for action. Neurons do not go through mitosis, and usually cannot be replaced after being destroyed, although astrocytes have been observed to turn into neurons as they are sometimes pluripotent.
