Dynamic Power Management for Neuromorphic Many-Core Systems [PDF]
, 2019 This work presents a dynamic power management architecture for neuromorphic many core systems such as SpiNNaker. A fast dynamic voltage and frequency scaling (DVFS) technique is presented which allows the processing elements (PE) to change their supply ...

Electrical synapses and their functional interactions with chemical synapses [PDF]
Nature Reviews Neuroscience, 2014 Brain function relies on the ability of neurons to communicate with each other. Interneuronal communication primarily takes place at synapses, where information from one neuron is rapidly conveyed to a second neuron. There are two main modalities of synaptic transmission: chemical and electrical. Far from functioning independently and serving unrelated

A Direct Comparison of Different Measures for the Strength of Electrical Synapses
Frontiers in Cellular Neuroscience, 2019 During the last decades it became increasingly evident that electrical synapses are capable of activity-dependent plasticity. However, measuring the actual strength of electrical transmission remains difficult.

Mutations in shaking-B prevent electrical synapse formation in the Drosophila giant fiber system [PDF]
, 1996 The giant fiber system (GFS) is a simple network of neurons that mediates visually elicited escape behavior in Drosophila. The giant fiber (GF), the major component of the system, is a large, descending interneuron that relays visual stimuli to the ...

eLife, 2021 Gap junctions between neurons serve as electrical synapses, in addition to conducting metabolites and signaling molecules. During development, early-appearing gap junctions are thought to prefigure chemical synapses, which appear much later.

Synchronous Behavior of Two Coupled Electronic Neurons [PDF]
, 2000 We report on experimental studies of synchronization phenomena in a pair of analog electronic neurons (ENs). The ENs were designed to reproduce the observed membrane voltage oscillations of isolated biological neurons from the stomatogastric ganglion of ...

The Variable Strength of Electrical Synapses [PDF]
Neuron, 2016 In contrast to chemical synapses, less is known regarding the determinants of the strength of electrical synapses. New evidence from Szoboszlay et al. (2016) shows that the number of gap junctions is the dominant factor underlying the strength of electrical coupling between cerebellar interneurons.

Mixed synapses reconcile violations of the size principle in zebrafish spinal cord
eLife, 2022 Mixed electrical-chemical synapses potentially complicate electrophysiological interpretations of neuronal excitability and connectivity. Here, we disentangle the impact of mixed synapses within the spinal locomotor circuitry of larval zebrafish.
