Although the computational capabilities of neural networks are determined by their structure, the current understanding of the relationships between a neural network’s architecture and function is still primitive. Here we reveal that a neural network’s modular architecture plays a vital role in determining the neural dynamics and memory performance of the network of threshold neurons. In particular, we demonstrate that there exists an optimal modularity for memory performance, where a balance between local cohesion and global connectivity is established, allowing optimally modular networks to remember longer. Our results suggest that insights from dynamical analysis of neural networks and information-spreading processes can be leveraged to better design neural networks and may shed light on the brain’s modular organization. 000002028 700__ $$aRodriguez, Nathaniel 000002028 700__ $$aIzquierdo, Eduardo J. 000002028 700__ $$aAhn, Yong Yeol 000002028 773__ $$tNetwork Neuroscience 000002028 773__ $$j3 000002028 8560_ $$fyyahn@indiana.edu 000002028 85642 $$hElectronic Resource$$uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6497001 000002028 909CO $$ooai:iu.tind.io:2028$$pGLOBAL_SET 000002028 980__ $$aPUBART
