Higher-order correlations

…atoms reveal spatial density and spin correlations, including higher-order correlations. The discussion explains how this experimental access opens questions that were difficult to investigate with earlier probes of dilute quantum matter.

…Here, we show that third and higher-order correlations in synaptic connectivities have a large impact on neuronal dynamics. Strong triangular cyclic correlations in a network su

The current dogma in neuroscience is that neurons primarily convey stimulus information through their firing rate. However, recent studies suggest a remarkable speed of sensory processing which may be incompatible with traditional rate-coding schemes, and it has been hypothesized that sensory encoding may rely on the spike timing relationships among neurons (Thorpe et al., 2001 and Resulaj et al., 2018). To study multi-neuron spiking patterns, we developed SpikeShip, an unsupervised, linear, geometry-based dissimilarity measure that aligns spikes across pairs of epochs based on optimal transpo
