Stable propagation of synchronous spiking in cortical neural networks.
Diesmann M, Gewaltig MO, Aertsen A. Diesmann M, et al. Among authors: aertsen a. Nature. 1999 Dec 2;402(6761):529-33. doi: 10.1038/990101. Nature. 1999. PMID: 10591212
Here we show that precisely synchronized action potentials can propagate within a model of cortical network activity that recapitulates many of the features of biological systems. An attractor, yielding a stable spiking precision in the (sub)millisecond range, gover …

Detecting higher-order interactions among the spiking events in a group of neurons.
Martignon L, Von Hasseln H, Grün S, Aertsen A, Palm G. Martignon L, et al. Among authors: aertsen a. Biol Cybern. 1995 Jun;73(1):69-81. doi: 10.1007/BF00199057. Biol Cybern. 1995. PMID: 7654851
Our first step is to represent a frequency distribution as a Markov field on the minimal graph it induces. We then show the invariance of this graph with regard to changes of state. ...We demonstrate the various steps of our method in the situation of an empirical f …

Dynamic synchronization between multiple cortical motor areas and muscle activity in phasic voluntary movements.
Feige B, Aertsen A, Kristeva-Feige R. Feige B, et al. Among authors: aertsen a. J Neurophysiol. 2000 Nov;84(5):2622-9. doi: 10.1152/jn.2000.84.5.2622. J Neurophysiol. 2000. PMID: 11068003
During the movement execution a low-frequency (2-14 Hz) synchronization was found. Using a novel analysis, phase-reference analysis, we were able to extract the EMG-coherent EEG maps for both, low- and high-frequency beta range synchronization. The electrical source …

Spike synchronization and rate modulation differentially involved in motor cortical function.
Riehle A, Grün S, Diesmann M, Aertsen A. Riehle A, et al. Among authors: aertsen a. Science. 1997 Dec 12;278(5345):1950-3. doi: 10.1126/science.278.5345.1950. Science. 1997. PMID: 9395398
Simultaneously recorded activities of neurons in the primary motor cortex of monkeys during performance of a delayed-pointing task exhibited context-dependent, rapid changes in the patterns of coincident action potentials. ...

Dynamics of neuronal interactions in monkey cortex in relation to behavioural events.
Vaadia E, Haalman I, Abeles M, Bergman H, Prut Y, Slovin H, Aertsen A. Vaadia E, et al. Among authors: aertsen a. Nature. 1995 Feb 9;373(6514):515-8. doi: 10.1038/373515a0. Nature. 1995. PMID: 7845462
Here we show that correlated firing between single neurons, recorded simultaneously in the frontal cortex of monkeys performing a behavioural task, evolves within a fraction of a second, and in systematic relation to behavioural events. ...These findings supp …
