Scientists have built a computer ‘brain circuit’, or artificial neural network, that mirrors human decision-making processes and sheds light on how circuits might be altered in psychiatric diseases, a new study published today in eLife reports.

The model identifies a potential mechanism for the impaired decision making that is commonly seen in schizophrenia, involving the reduced activity of molecules in the brain called NDMA receptors. These results provide new insight that may inform the development of future treatments for neuropsychiatric conditions.

A major challenge in psychiatry is to relate changes that occur at nerve synapses in the brain to the cognitive processes that cause symptoms of disorders such as schizophrenia. Computational modelling of brain circuits can fill in these gaps. By altering the circuit model at the synapse level, you can make predictions of nerve activity and behaviours, and then test

“A major challenge in psychiatry is to relate changes that occur at nerve synapses in the brain to the cognitive processes that cause symptoms of disorders such as schizophrenia,” explains lead author Dr. Sean Cavanagh, who is an MBPhD student at the UCL Queen Square Institute of Neurology, London, UK. “Computational modeling of brain circuits can fill in these gaps.

If you work 48 weeks in the year and spend a conservative 5 hours per week commuting to and from work, you are spending 240 hours per year driving. This takes time away from family, hobbies, friends, and much more. How can technology be leveraged to gain that time back?

Up until recent years, the only option for working was to physically go into an office to put in your 40-50 hours per week behind a stuffy desk surrounded by people you may or may not enjoy working with. As technology has evolved, so has the flexibility of whether you work at the office, at home, at the beach, or some other locale.

While technology does make it easier for employers to allow telecommuting, there is still a trust factor that comes into play. There are ways each employer can measure productivity differently, but some employers are simply more comfortable … Read More
