Spatial Directionality Found in Frontal-Parietal Attentional Networks.

Neuroscience journal

Hossain G, Myers MH, Kozma R.
PMID: 30228978
Neurosci J. 2018 Aug 30;2018:7879895. doi: 10.1155/2018/7879895. eCollection 2018.

Research in last few years on neurophysiology focused on several areas across the cortex during cognitive processing to determine the dominant direction of electrical activity. However, information about the frequency and direction of episodic synchronization related to higher cognitive...

Past and potential future population dynamics of three grouse species using ecological and whole genome coalescent modeling.

Ecology and evolution

Kozma R, Lillie M, Benito BM, Svenning JC, Höglund J.
PMID: 30038766
Ecol Evol. 2018 May 29;8(13):6671-6681. doi: 10.1002/ece3.4163. eCollection 2018 Jul.

Studying demographic history of species provides insight into how the past has shaped the current levels of overall biodiversity and genetic composition of species, but also how these species may react to future perturbations. Here we investigated the demographic...

Robust sequential working memory recall in heterogeneous cognitive networks.

Frontiers in systems neuroscience

Rabinovich MI, Sokolov Y, Kozma R.
PMID: 25452717
Front Syst Neurosci. 2014 Nov 14;8:220. doi: 10.3389/fnsys.2014.00220. eCollection 2014.

Psychiatric disorders are often caused by partial heterogeneous disinhibition in cognitive networks, controlling sequential and spatial working memory (SWM). Such dynamic connectivity changes suggest that the normal relationship between the neuronal components within the network deteriorates. As a result,...

Cinematic Operation of the Cerebral Cortex Interpreted via Critical Transitions in Self-Organized Dynamic Systems.

Frontiers in systems neuroscience

Kozma R, Freeman WJ.
PMID: 28352218
Front Syst Neurosci. 2017 Mar 14;11:10. doi: 10.3389/fnsys.2017.00010. eCollection 2017.

Measurements of local field potentials over the cortical surface and the scalp of animals and human subjects reveal intermittent bursts of beta and gamma oscillations. During the bursts, narrow-band metastable amplitude modulation (AM) patters emerge for a fraction of...

Evolutionary Advantages of Stimulus-Driven EEG Phase Transitions in the Upper Cortical Layers.

Frontiers in systems neuroscience

Kozma R, Baars BJ, Geld N.
PMID: 34955771
Front Syst Neurosci. 2021 Dec 08;15:784404. doi: 10.3389/fnsys.2021.784404. eCollection 2021.

Spatio-temporal brain activity monitored by EEG recordings in humans and other mammals has identified beta/gamma oscillations (20-80 Hz), which are self-organized into spatio-temporal structures recurring at theta/alpha rates (4-12 Hz). These structures have statistically significant correlations with sensory stimuli...

Reflections on a giant of brain science: How lucky we are having Walter J. Freeman as our beacon in cognitive neurodynamics research.
