متن کاملGeneration of spatiotemporally correlated spike trains and local field potentials using a multivariate autoregressive process.
Experimental advances allowing for the simultaneous recording of activity at multiple sites have significantly increased our understanding of the spatiotemporal patterns in neural activity. The impact of such patterns on neural coding is a fundamental question in neuroscience. The simulation of spike trains with predetermined activity patterns is therefore an important ingredient in the study o...
متن کاملEvidence for slow (2-10 Hz) and gamma frequency coherence between spike trains and local field potentials in the cerebellum
7 A method for detecting relationships between single-unit spike trains and local %eld potentials (LFPs) was developed and applied to recordings from rat cerebellum. LFPs were repeatedly 9 %ltered with a shifting frequency window. The resulting traces were transformed into peak-time point processes for comparison with spike trains using “relative-phase” analysis (Biol. Cyber11 net., in press). ...
متن کاملHierarchical Multivariate CAR Models for Spatio-Temporally Correlated Survival Data
Survival models have a long history in the biomedical and biostatistical literature, and are enormously popular in the analysis of time-to-event data. Very often these data will be grouped into strata, such as clinical sites, geographic regions, and so on. Such data will often be available over multiple time periods, and for multiple diseases. In this paper, we consider hierarchical spatial pro...
متن کاملMultiplexed coding by cerebellar Purkinje neurons
Purkinje cells (PC), the sole output neurons of the cerebellar cortex, encode sensorimotor information, but how they do it remains a matter of debate. Here we show that PCs use a multiplexed spike code. Synchrony/spike time and firing rate encode different information in behaving monkeys during saccadic eye motion tasks. Using the local field potential (LFP) as a probe of local network activity...
