Researchers have long been using the field of optogenetics, a biological technique involving the use of light to control cells in living tissue, typically neurons, which have been engineered to … Continue Reading Researchers wirelessly hack master gene using nanophotonics.
Genetically-coded brain circuits can switch feeding and drinking behaviours on and off in mice.
The decision to engage in food-seeking behaviour depends on homeostatic signals relating to energy balance and the presence of competing motivational drives, as well as learned brain cues signaling food … Continue Reading Neuroimaging shows the effect of hunger on the brain’s response to food cues.
Damage to axons in the central nervous system (CNS) typically results in permanent damage and severed axons in the adult mammalian CNS do not spontaneously regenerate to restore lost functions. … Continue Reading Researchers regenerate damaged nerves via the eye using optogenetics.
The skin is the largest organ in the human body and is made up of three layers, the epidermis, dermis and the fat layer. The epidermis is the outer layer … Continue Reading Artificially intelligent synthetic skin interacts with brain cells.
In general, infertility is defined as not being able to get pregnant after one year of unprotected sex. Causes of infertility or reproductive problems include disease and aging, with male … Continue Reading Researchers identify specific neurons which activate fertility master switch.
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.
A team of researchers from Washington University, National Institutes of Health and University of Illinois have developed a wireless device the width of a human hair that can be implanted in … Continue Reading Microfluid device can control neurons and delivery drugs wirelessly.
Researchers successfully implant and control light-sensitive opioid receptors in mice via optogenetics.
Despite the abuse potential of opioid drugs, they have long been the best option for patients suffering from severe pain. The drugs interact with receptors on brain cells to tamp … Continue Reading Researchers successfully implant and control light-sensitive opioid receptors in mice via optogenetics.
A new study by Brown University neuroscientists details how the neocortex selectively samples from the flow of sensory information that might otherwise flood it. The team state that the usual … Continue Reading Researchers begin to map the corticothalamic pathway in selective neuroplasticity.
Deadly brain tumours called high-grade gliomas grow with the help of nerve activity in the cerebral cortex, according to a new study by researchers at the Stanford University School of … Continue Reading Researchers show that brain cancer proliferation is stimulated by nerve activity in the cortex.
A precision genetic analysis has yielded a surprising result, a network of neurons control breathing within the vagus nerve. Among these function-specific network of neurons, two types are dedicated to … Continue Reading Researchers identify neural networks within the vagus nerve responsible for breathing.
The ability to learn associations between events is critical for survival, but it has not been clear how different pieces of information stored in memory may be linked together by … Continue Reading Researchers optogenetically create artificial link between unrelated memories.
Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link … Continue Reading Researchers identify gated-intermediary neuron system which acts as synaptic cloaking device.
Researchers at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have added another piece to the complex puzzle of how the brain controls one of the most essential … Continue Reading Optogenetics study identifies neurons important for induction of natural REM sleep.
For the first time researchers have imaged and linked live individual brain cells to specific basic behaviours.
Researchers at the UNC School of Medicine have used new deep-brain imaging techniques to link the activity of individual, genetically similar neurons to particular behaviours of mice. Specifically, for the … Continue Reading For the first time researchers have imaged and linked live individual brain cells to specific basic behaviours.
