For the greatest chance of survival, cancer screening needs to detect the disease before symptoms appear. Current cancer detection involves blood tests, urine tests, DNA tests, and/or medical imaging, however, … Continue Reading DNA computer can detect cancer on a single-cell basis.
Depression is the leading cause of disability worldwide, affecting more than 300 million people globally, characterized by persistent sadness and a loss of interest in activities, accompanied by an inability … Continue Reading Gender-distinct circuit for depression identified in mice.
Mining the gut microbiota, the trillions of microbes living in our digestive system is a promising approach for developing new sensors providing a response to disease and abnormalities in the … Continue Reading Bacteria containing DNA computer provides diagnostics for the gut microbiota.
Acting as natural computers, our brains contain trillions of cells to store memory and control the body’s functions and emotions. Around one in ten of the countless cells in the … Continue Reading Microglia filmed shaping synapses for the first time.
Genetically-coded brain circuits can switch feeding and drinking behaviours on and off in mice.
It is known that repeated cocaine-use results in the development of behavioural sensitization, accompanied by a decrease in excitatory synaptic strength in the nucleus accumbens (NAc). Furthermore, glial cells in … Continue Reading Microglia-based mechanism that reduces effect of cocaine on the brain identified.
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.
First detailed blueprint for a spinal circuit for integrating motor and sensory commands from the brain.
Walking across an icy parking lot in winter, and remaining upright, takes intense concentration. But a new discovery suggests that much of the balancing act that the human body performs … Continue Reading First detailed blueprint for a spinal circuit for integrating motor and sensory commands from the brain.
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.
After an incomplete spinal cord injury, the body can partially recover basic motor function. So-called muscle spindles and associated sensory circuits back to the spinal chord promote the establishment of … Continue Reading Trigger mechanism for recovery after spinal cord injury identified.
Within a few months after drug withdrawal, patients in recovery from dependence on prescription pain medications may show signs that the body’s natural reward systems are normalizing. The study from … Continue Reading Researchers map clinical neuroimaging markers for opioid withdrawal.
