====== Neurona@Home ====== ===== Project Description ===== Neurona@Home is a BOINC-based project with the main aim of simulating the behavior of a large assembly of cellular automata neurons connected in a complex network. Main Facts * A human brain contains more than 10.000 million neurons with an average of 10.000 synaptic connections projecting from each neuron to other neurons. * Even the mini-brains of some insects are indeed very complex: Honeybee brains contain around 960.000 neurons which give them astounding memory and behavioral repertoire for their size. * It is known that the synchronization of the firing of large assemblies of neurons is related to odour discrimination in insects. * In Humans synchronous oscillations are also present but they are usually related to higher-order functions such as attention, memory and conscious awareness. * The origin and even the role of these oscillations are still poorly understood. Model key issues * We consider a model in which a set of excitatory and inhibitory nodes can activate or deactivate neighbor nodes according to a set of probabilistic rules. The cellular automata neuron is a very simple artifact with only three states: firing, resting or refractory but we are interested in the features of the brain that emerge as a consequence of its complex network structure. * To this aim we should consider an artificial brain with 1.000.000 neurons, a number that exceeds the typical size of an insect brain. Our project's simulations of the cellular automata brain in a random network should allow us to understand: * The emergence of brain oscillations as collective firing. * The effectiveness of artificial neural networks as discriminant devices. * The role of the network structure of brains in information processing. ==== Credentials ==== * Website: **http://falua.cesfelipesegundo.com/Neurona/** * Join to team: **[[http://falua.cesfelipesegundo.com/Neurona/team_display.php?teamid=18|Ukraine]]** ==== Author(s) ==== You can contact the researcher in charge for additional information: * Dr. Javier Villanueva * Email jvillanueva AT pdi DOT ucm DOT es * Phone number +34 91 809 92 00 extension 210 * Universidad Complutense de Madrid - CES Felipe II * Aranjuez - Madrid - Spain ==== Significant dates ==== * Initial release: **14 Jun 2011** * Date of completion: Project is Active ===== Features ===== ==== Hardware requirements ==== Due to the nature of the network being simulated, this project requires a HUGE amount of RAM, between 3 and 6 Gigabytes per Work Unit, and quite likely this quantity will increase in the next months as the investigation goes further. You will need a suitable 64 bit Linux or Windows PC (due to the RAM requirements there is no 32 bit worker available). Because of this, **subscription to this project is made only by invitation code upon request of the volunteer**. ==== OSes & Applications ==== | | Ideologias@Home | |Windows 64bit | {{:ru:yes.gif|}} | |Linux 64bit | {{:ru:yes.gif|}} |
