Modelling how neurons work together

A highly accurate model of how neurons behave when performing complex movements could aid in the design of robotic limbs which behave more realistically. Accurate models like these can really aid in the understanding of the incredibly complex dynamics at work in the human brain - Guillaume Hennequin A newly-developed, highly accurate representation of the way in which neurons behave when performing movements such as reaching could not only enhance understanding of the complex dynamics at work in the brain, but aid in the development of robotic limbs which are capable of more complex and natural movements. Researchers from the University of Cambridge, working in collaboration with the University of Oxford and the Ecole Polytechnique Fédérale de Lausanne (EPFL), have developed a new model of a neural network, offering a novel theory of how neurons work together when performing complex movements. The results are published in the 18 June edition of the journal Neuron . While an action such as reaching for a cup of coffee may seem straightforward, the millions of neurons in the brain's motor cortex must work together to prepare and execute the movement before the coffee ever reaches our lips. When we reach for the much-needed cup of coffee, the neurons spring into action, sending a series of signals from the brain to the hand. These signals are transmitted across synapses - the junctions between neurons.
