Circuit topology for synchronizing neurons in spontaneously active networks.
Spike synchronization underlies information processing and storage in the brain. But how can neurons synchronize in a noisy network? By exploiting a high-speed (500-2,000 fps) multineuron imaging technique and a large-scale synapse mapping method, we directly compared spontaneous activity patterns and anatomical connectivity in hippocampal CA3 networks ex vivo. As compared to unconnected pairs,...
متن کاملSloppiness in spontaneously active neuronal networks.
Various plasticity mechanisms, including experience-dependent, spontaneous, as well as homeostatic ones, continuously remodel neural circuits. Yet, despite fluctuations in the properties of single neurons and synapses, the behavior and function of neuronal assemblies are generally found to be very stable over time. This raises the important question of how plasticity is coordinated across the n...
متن کاملIdentifying Temporal Codes in Spontaneously Active Sensory Neurons
The manner in which information is encoded in neural signals is a major issue in Neuroscience. A common distinction is between rate codes, where information in neural responses is encoded as the number of spikes within a specified time frame (encoding window), and temporal codes, where the position of spikes within the encoding window carries some or all of the information about the stimulus. O...
متن کاملEffective Subnetwork Topology for Synchronizing Interconnected Networks of Coupled Phase Oscillators
A system consisting of interconnected networks, or a network of networks (NoN), appears diversely in many real-world systems, including the brain. In this study, we consider NoNs consisting of heterogeneous phase oscillators and investigate how the topology of subnetworks affects the global synchrony of the network. The degree of synchrony and the effect of subnetwork topology are evaluated bas...
متن کاملSynchronizing Aysnchronous Bounded Delay Networks
An efficient way to synchronize an asynchronous network with a bounded delay message delivery is presented. Two types of synchronlzaiioo algorithms are presented. Both types require an initializing phase that costs IEl messages (where IEl is the number of links). The first requires an additional hit in every message and increases the time complexily by a factor of 2. The second does not require...
