Vector strength after Goldberg, Brown, and von Mises: biological and mathematical perspectives.

Biological cybernetics

van Hemmen JL.
PMID: 23982848
Biol Cybern. 2013 Aug;107(4):385-96. doi: 10.1007/s00422-013-0561-7. Epub 2013 Aug 27.

The vector strength, a number between 0 and 1, is a classical notion in biology. It was first used in neurobiology by Goldberg and Brown (J Neurophys 31:639-656, 1969) but dates back at least to von Mises (Phys Z...

Phase response approaches to neural activity models with distributed delay.

Biological cybernetics

Winkler M, Dumont G, Schöll E, Gutkin B.
PMID: 34853889
Biol Cybern. 2021 Dec 02; doi: 10.1007/s00422-021-00910-9. Epub 2021 Dec 02.

In weakly coupled neural oscillator networks describing brain dynamics, the coupling delay is often distributed. We present a theoretical framework to calculate the phase response curve of distributed-delay induced limit cycles with infinite-dimensional phase space. Extending previous works, in...

Electric signal synchronization as a behavioural strategy to generate social attention in small groups of mormyrid weakly electric fish and a mobile fish robot.

Biological cybernetics

Worm M, Landgraf T, von der Emde G.
PMID: 34398266
Biol Cybern. 2021 Dec;115(6):599-613. doi: 10.1007/s00422-021-00892-8. Epub 2021 Aug 16.

African weakly electric fish communicate at night by constantly emitting and perceiving brief electrical signals (electric organ discharges, EOD) at variable inter-discharge intervals (IDI). While the waveform of single EODs contains information about the sender's identity, the variable IDI...

Steps towards a computational ethology: an automatized, interactive setup to investigate filial imprinting and biological predispositions.

Biological cybernetics

Zanon M, Lemaire BS, Vallortigara G.
PMID: 34272970
Biol Cybern. 2021 Dec;115(6):575-584. doi: 10.1007/s00422-021-00886-6. Epub 2021 Jul 17.

Soon after hatching, the young of precocial species, such as domestic chicks or ducklings, learn to recognize their social partner by simply being exposed to it (imprinting process). Even artificial objects or stimuli displayed on monitor screens can effectively...

Geodesic-based distance reveals nonlinear topological features in neural activity from mouse visual cortex.

Biological cybernetics

Beshkov K, Tiesinga P.
PMID: 34816322
Biol Cybern. 2021 Nov 23; doi: 10.1007/s00422-021-00906-5. Epub 2021 Nov 23.

An increasingly popular approach to the analysis of neural data is to treat activity patterns as being constrained to and sampled from a manifold, which can be characterized by its topology. The persistent homology method identifies the type and...

Mathematization of nature: how it is done.

Biological cybernetics

van Hemmen JL.
PMID: 34837542
Biol Cybern. 2021 Dec;115(6):655-664. doi: 10.1007/s00422-021-00914-5.

Natural phenomena can be quantitatively described by means of mathematics, which is actually the only way of doing so. Physics is a convincing example of the mathematization of nature. This paper gives an answer to the question of how...

The creation of phenomena in interactive biorobotics.

Biological cybernetics

Datteri E.
PMID: 34714419
Biol Cybern. 2021 Dec;115(6):629-642. doi: 10.1007/s00422-021-00900-x. Epub 2021 Oct 29.

In so-called interactive biorobotics, robotic models of living systems interact with animals in controlled experimental settings. By observing how the focal animal reacts to the stimuli delivered by the robot, one tests hypotheses concerning the determinants of animal behaviour...

Partial directed coherence: twenty years on some history and an appraisal.

Biological cybernetics

Baccalá LA, Sameshima K.
PMID: 34100992
Biol Cybern. 2021 Jun;115(3):195-204. doi: 10.1007/s00422-021-00880-y. Epub 2021 Jun 08.

Here while we reminisce about how partial directed coherence was proposed, its motivation and evolution, we take the opportunity to relate it to some of its kin quantities and some of its offspring. Emphasis is placed on our development...

Comprehensive characterization of oscillatory signatures in a model circuit with PV- and SOM-expressing interneurons.

Biological cybernetics

Ter Wal M, Tiesinga PHE.
PMID: 34628539
Biol Cybern. 2021 Oct;115(5):487-517. doi: 10.1007/s00422-021-00894-6. Epub 2021 Oct 09.

Neural circuits contain a wide variety of interneuron types, which differ in their biophysical properties and connectivity patterns. The two most common interneuron types, parvalbumin-expressing and somatostatin-expressing cells, have been shown to be differentially involved in many cognitive functions....

Control of multistability in ring circuits of oscillators.

Biological cybernetics

Canavier CC, Baxter DA, Clark JW, Byrne JH.
PMID: 21547616
Biol Cybern. 1999 Feb;80(2):87-102. doi: 10.1007/s004220050507.

The essential dynamics of some biological central pattern generators (CPGs) can be captured by a model consisting of N neurons connected in a ring. These circuits, like many oscillatory nonlinear circuits of sufficient complexity, are capable of multistability, that...
