Forward and reverse delay-driven hippocampal replay without symmetric plasticity
Georg Reich, Matthew Cook, Klaus Obermayer +1
Hippocampal replay is a phenomenon observed in mammals and songbirds where neural activation sequences experienced during wakeful periods are repeated during rest or sleep. This me…
Applications of optimal nonlinear control to a whole-brain network of FitzHugh-Nagumo oscillators
Teresa Chouzouris, Nicolas Roth, Caglar Cakan +1
We apply the framework of optimal nonlinear control to steer the dynamics of a whole-brain network of FitzHugh-Nagumo oscillators. Its nodes correspond to the cortical areas of an…
Spatiotemporal patterns of adaptation-induced slow oscillations in a whole-brain model of slow-wave sleep
Caglar Cakan, Cristiana Dimulescu, Liliia Khakimova +3
During slow-wave sleep, the brain is in a self-organized regime in which slow oscillations (SOs) between up- and down-states travel across the cortex. While an isolated piece of co…
Biophysically grounded mean-field models of neural populations under electrical stimulation
Caglar Cakan, Klaus Obermayer
Electrical stimulation of neural systems is a key tool for understanding neural dynamics and ultimately for developing clinical treatments. Many applications of electrical stimulat…
A computational study on synaptic and extrasynaptic effects of astrocyte glutamate uptake on orientation tuning in V1
Konstantin Mergenthaler, Franziska Oschmann, Jeremy Petravicz +3
Astrocytes affect neural transmission by a tight control via glutamate transporters on glutamate concentrations in direct vicinity to the synaptic cleft and by extracellular glutam…
Low-dimensional spike rate models derived from networks of adaptive integrate-and-fire neurons: Comparison and implementation
Moritz Augustin, Josef Ladenbauer, Fabian Baumann +1
The spiking activity of single neurons can be well described by a nonlinear integrate-and-fire model that includes somatic adaptation. When exposed to fluctuating inputs sparsely c…
