Metastable dynamics of neural circuits and networks

BAW Brinkman, H Yan, A Maffei, IM Park… - Applied Physics …, 2022 - pubs.aip.org
Cortical neurons emit seemingly erratic trains of action potentials or “spikes,” and neural
network dynamics emerge from the coordinated spiking activity within neural circuits. These …

Non-reciprocal phase transitions

M Fruchart, R Hanai, PB Littlewood, V Vitelli - Nature, 2021 - nature.com
Out of equilibrium, a lack of reciprocity is the rule rather than the exception. Non-reciprocity
occurs, for instance, in active matter,,,,–, non-equilibrium systems,–, networks of neurons …

Neural correlates of the LSD experience revealed by multimodal neuroimaging

RL Carhart-Harris… - Proceedings of the …, 2016 - National Acad Sciences
Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the

Activation of serotonin 2A receptors underlies the psilocybin-induced effects on α oscillations, N170 visual-evoked potentials, and visual hallucinations

M Kometer, A Schmidt, L Jäncke… - Journal of …, 2013 - Soc Neuroscience
Visual illusions and hallucinations are hallmarks of serotonergic hallucinogen-induced
altered states of consciousness. Although the serotonergic hallucinogen psilocybin activates …

intoxication induced by three main classes of drugs: psychostimulants, psychedelics, and …

Effect of frequency and rhythmicity on flicker light-induced hallucinatory phenomena

IA Amaya, N Behrens, DJ Schwartzman, T Hewitt… - Plos one, 2023 - journals.plos.org
Flicker light stimulation (FLS) uses stroboscopic light on closed eyes to induce transient

Giant amplification of noise in fluctuation-induced pattern formation

T Biancalani, F Jafarpour, N Goldenfeld - Physical review letters, 2017 - APS
The amplitude of fluctuation-induced patterns might be expected to be proportional to the
strength of the driving noise, suggesting that such patterns would be difficult to observe in …

Stochastic pattern formation and spontaneous polarisation: the linear noise approximation and beyond

AJ McKane, T Biancalani, T Rogers - Bulletin of mathematical biology, 2014 - Springer
We review the mathematical formalism underlying the modelling of stochasticity in biological
systems. Beginning with a description of the system in terms of its basic constituents, we …
