$ 20 million for the National Science Foundation (NSF), to support research into the development of nanoscale probes that can record
the activity of neural networks; information processing technology that can handle the flood of data generated by BRAIN research; and better understanding of the neural representation of thoughts, emotions, actions, and memories
Researchers from the MRC Centre for Developmental Neurobiology (MRC CDN) at the Institute of Psychiatry, Psychology & Neuroscience (IoPPN), King's College London, have discovered a new molecular «switch» that controls the properties of neurons in response to changes in
the activity of their neural network.

neural network — a computing system modelled after the neuron
activity in animal brains that can basically learn on its own — can effectively differentiate between similar plants with an amazing accuracy
of nearly 100 %.
These research findings deliver new insight into the neuronal control
of movement termination in vertebrates: «Stop cells» are brainstem neurons that affect
neural networks in the medulla as command neurons and quickly end body
activity.

neural activity in the connector hubs to
activity in each

networks during all the tasks recorded in the BrainMap database.
The study, just published in the Proceedings
of the National Academy
of Sciences, found heightened
neural activity in the brain's connector hubs during complex tasks, such as puzzles and video games, while
networks dedicated to specific functions did not need to put in extra work.

of the Y4 receptor, I will use the results to design efficient and accurate descriptors that can be used with artificial
neural networks to predict
activity at the Y4 receptor based on a small molecule's structural properties.

of the brain called the default mode
network, which is involved in

of neurons that fire together, creating electrochemical pathways — shape themselves according to that
activity or memory.
