Virtual drug quiets noise in heart tissue images

If you've ever tried taking a picture of a puppy, you likely ended up with a blur of fur. Now try reading a stock ticker on the puppy's fur, and you'll have the challenge that faces researchers studying electrical conduction ...

Long-term use of steroids could impair memory, study finds

Memory impairment associated with steroid use has been identified in a new study. The University of Bristol-led findings, published in PNAS, show great potential for the identification of drugs that could be adapted to treat ...

Progress in unlocking the brain's 'code' for depression

Clinical depression is a common psychiatric condition with often devastating consequences. A new study in Biological Psychiatry advances our fundamental understanding of the neural circuitry of depression in the human brain.

Neuroscience

New findings on neuronal activities in the sensorimotor cortex

An interdisciplinary research team at the University of Freiburg has found important clues about the functioning of the sensorimotor cortex. The new findings on neuronal activities in this brain area could be helpful for ...

Neuroscience

First to measure the concerted activity of a neuronal circuit

Neurobiologists from the Friedrich Miescher Institute for Biomedical Research have been the first to measure the concerted activity of a neuronal circuit in the retina as it extracts information about a moving object. With ...

Neuroprosthesis gives rats the ability to 'touch' infrared light

Researchers have given rats the ability to "touch" infrared light, normally invisible to them, by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes ...

Electrophysiology

Electrophysiology (from Greek ἥλεκτρον, ēlektron, "amber" [see the etymology of "electron"]; φύσις, physis, "nature, origin"; and -λογία, -logia) is the study of the electrical properties of biological cells and tissues. It involves measurements of voltage change or electric current on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and particularly action potential activity. Recordings of large-scale electric signals from the nervous system such as electroencephalography, may also be referred to as electrophysiological recordings.
