A lack of understanding currently veils the field of brain injury, with sufferers undergoing cataclysmic personality changes as well as other chronic health problems affecting the whole body. Electronics are … Continue Reading Artificial and biological neurons communicate over the internet.
Tapping into the part of the body where cells exist exhibiting neuron-like behavior to tap directly into the central nervous system with these out-of-brain neuronal colonies constantly being searched for. … Continue Reading Neuron-like activity identified in skin cells.
Viruses have evolved to be highly effective vehicles for delivering genes into cells, with these vectors becoming critical in delivering genes to treat disease or label neurons. As viral vectors … Continue Reading Novel viral vectors deliver useful cargo to neurons throughout the brain and body.
Neurons are continuously exposed to signals generated by the extracellular environment and the senses to drive key biological tasks. This ability has been exploited to engineer interfaces with nanostructures to … Continue Reading Nano-prosthetics developed to repair neural circuitry.
Masters of survival in any environment, cancer cells rely on the healthy cells surrounding them for sustenance, literally leeching life from their host. They do this by rerouting blood vessels … Continue Reading Study shows neurons support cancer growth throughout the body.
Stem cell treatments for neurodegenerative diseases are expected to reach clinical trials soon. One major task en route to the clinic is to generate standardized good manufacturing practice (GMP)-grade human-pluripotent … Continue Reading Breakthrough in the production of dopamine neurons for Parkinson’s disease.
It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.
It is known that brain–computer interfaces record brain activity and translate the information into useful control signals. They can be used to restore function to people with paralysis by controlling … Continue Reading New technology for reading signals directly from the brain allows typing at 12 words per minute.
Epilepsy is a common neurological condition characterized by spontaneous, recurrent synchronous discharges of a population of neurons, unprovoked by a known proximal cause. Epilepsy is the second most common neurological … Continue Reading Relief for epilepsy at the scale of a single cell.
Stem cells are non-specialized cells found in different organs, which have the capacity to generate specialized cells in the body. In the adult brain, neural stem cells give rise to … Continue Reading Study shows cerebrospinal fluid signals control the behaviour of stem cells in the brain.
Compared to other mammals, humans have the largest cerebral cortex. A sheet of brain cells that folds in on itself multiple times in order to fit inside the skull, the … Continue Reading Researchers identify and map a previously unknown gene critical for human brain development.
Brazil is in the midst of an unprecedented epidemic of Zika virus (ZIKV), a flavivirus that is transmitted by mosquitoes and sexually, which was first detected in the country in … Continue Reading New research provides mechanism and evidence of how Zika virus causes microcephaly in newborns.
In the United States alone, moderate and severe dry eye disease afflicts nearly 5 million individuals over age 65, and many more suffer from less-severe cases. Dry eye symptoms range … Continue Reading Neural stimulation for dry eye enters FDA clinical trial phase.
Cocaine is a strong central nervous system stimulant that increases levels of the neurotransmitter dopamine in brain circuits regulating pleasure and movement. Normally, dopamine is released by neurons in these … Continue Reading Researchers begin to map brain regions and circuits changed by cocaine-use.
Many diseases involve structural changes in tissues, which are reflected in a change in their mechanical properties, such as elasticity. Using the sensitivity of their hands, and their detailed knowledge … Continue Reading Researchers have developed non-invasive palpation for the brain.
White adipose tissue, or fat tissue, serves as a storage depot for energy-rich triglycerides. In times of need this lipid storage can be released as part of an adaptive response … Continue Reading Researchers identify previously unknown neural mechanism responsible for fat breakdown.
