A new neuro-inspired system for pattern detection

A scientific team comprising researchers from the Center for Biomedical Technology (CTB) at UPM, University of La Laguna (ULL) and Institute for Cross-Disciplinary Physics and Complex System (IFISC, CSIC-UIB) has developed ...

New model mimics persistent interneuron loss seen in prematurity

Research-clinicians at Children's National Health System have created a novel preclinical model that mimics the persistent interneuron loss seen in preterm human infants, identifying interneuron subtypes that could become ...

Altered brain activity patterns of Parkinson's captured in mice

The tell-tale tremors of Parkinson's disease emerge from abnormal activity in a brain region crucial for voluntary movement. Using a mouse model of the disease, researchers at the Okinawa Institute of Science and Technology ...

Neuroscience

Brain represents optical illusion as delayed reality

A study of humans and monkeys published in JNeurosci has found the same subset of neurons encode actual and illusory complex flow motion. This finding supports, at the level of single neurons, what the Czech scientist Jan ...

Neuroscience

Modulating stress circuits

Stress contributes to psychiatric diseases including depression, eating disorders and addiction. Neurons that express the stress signal corticotropin releasing factor (CRF) in a brain region called the BNST are thought to ...

Statins could protect against motor neurone disease

High cholesterol has been found to be a possible risk factor for the development of motor neurone disease (MND), according to a large study of genetic data led in the UK by Queen Mary University of London, in collaboration ...

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.
