Collective signaling within the network manifests as patterned ne ural activity\, and is thought to support human cognition and adaptive beh avior. Recent technological advances permit macro-scale reconstructions of biological brain networks. These maps\, termed connectomes\, display mult iple non-random architectural features\, including heavy-tailed degree dis tributions\, segregated communities and a densely interconnected core. Yet \, how computation and functional specialization emerge from network archi tecture remains unknown. Here we reconstruct human brain connectomes using in vivo diffusion-weighted imaging\, and use reservoir computing to imple ment connectomes as artificial neural networks. We then train these neurom orphic networks to learn a memory encoding task. We show that biologically realistic neural architectures perform best when they display critical dy namics. We find that performance is driven by network topology\, and that the modular organization of intrinsic networks is computationally relevant . Throughout\, we observe a prominent interaction between network structur e and dynamics\, such that the same underlying architecture can support a wide range of memory capacity values as well as different functions (encod ing or decoding)\, depending on the dynamical regime the network is in. Th is work opens new opportunities to discover how the network organization o f the brain optimizes cognitive capacity.\n\nBio: Laura Usme is a PhD cand idate in the Integrated Program in Neuroscience at ºÃÉ«TV under the co-supervision of Dr. Bratislav MiÅ¡ić and Dr. Guillaume Lajoie. Her a cademic interests lie at the intersection of artificial intelligence and n euroscience. Broadly\, her research revolves around the structure-function relationship in biological brains. Specifically looking at understanding how network structure and dynamics interact to shape the computational cap acity of the brain\, and how we can use this knowledge to establish design principles for the development of better neuromorphic architectures.\n\n \nThe Feindel Virtual Brain and Mind (VBM) Seminar Series will advance the vision of Dr. William Feindel (1918–2014)\, Former Director of the Neuro (1972–1984)\, to constantly bridge the clinical and research realms. The t alks will highlight the latest advances and discoveries in neuropsychology \, cognitive neuroscience\, and neuroimaging.\n\nSpeakers will include sci entists from across The Neuro\, as well as colleagues and collaborators lo cally and from around the world. The series is intended to provide a virtu al forum for scientists and trainees to continue to foster interdisciplina ry exchanges on the mechanisms\, diagnosis and treatment of brain and cogn itive disorders.\n DTSTART:20210929T200000Z DTEND:20210929T210000Z SUMMARY:Feindel Virtual Brain and Mind Lecture Series: Learning function fr om structure in neuromorphic networks URL:/neuro/channels/event/feindel-virtual-brain-and-mi nd-lecture-series-learning-function-structure-neuromorphic-networks-332377 END:VEVENT END:VCALENDAR
