Easily accessible and highly habit-forming, alcohol is now one of the world’s most addictive substances, with roughly two billion individuals worldwide consuming it and three million associated with its misuse … Continue Reading Researchers map key neural circuit regulating alcohol consumption.
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.
Memorizing and predicting aversive or unpleasant events is a critical function of neural circuits responsible for survival and emotional well-being. There is much interest in how the brain creates the … Continue Reading Brain pathways of aversion identified.
The human brain is the source of a person’s thoughts, emotions, perceptions, actions, and memories. One challenge for neuroscience is to achieve an integrated understanding of brain-wide interactions, particularly the … Continue Reading Study identifies new function for the hippocampus.
To maintain homeostasis in the body, physiological imbalances produce motivational drives, one of which is thirst. This thirst produces a drive to seek and consume water, however, just how neural activity … Continue Reading Quench thirsting neurons in the brain identified.
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.
