Research interests

My long term interest is to better understand how the complex structure of neurons and dynamical intracellular signaling in dendrites and at synapses affect computational properties of the nervous system. My broader, philosophical motivation is to explore whether it is possible to entirely reduce human cognition to neuronal computation. I use approaches that are based on a close interaction between computational modeling and experimental methods.

Selected research topics

The dentate gyrus is part of the hippocampus which is thought to contribute to mechanisms of learning and memory via activity of dentate granule cells. I am interested in cellular and molecular mechanisms involved in the regulation of dentate network excitability and synaptic plasticity. In my recent work I have contributed to identifying several important molecular players (e.g. neuroligin-2, neuroligin-1 and collybistin) involved in the regulation of dentate physiology (Jedlicka et al. MCN 2009; Winkels, Jedlicka et al. Hippocampus 2009; Jedlicka et al. Cerebral Cortex 2011; Jedlicka, Vnencak et al. Brain Structure & Function 2015).   

* GABAergic inhibitory transmission regulates membrane potential dynamics in neuronal cells thereby crucially controlling excitability in the brain. The efficacy of synaptic inhibition is dynamic and strongly depends on ionic driving force for the chloride-permeable receptors. I want to learn more about general rules that govern spatio-temporal ionic dynamics at inhibitory synapses and their effects on dendritic computation. To address this important issue I have recently created a model of chloride accumulation and diffusion in morphologically realistic dendritic trees (Jedlicka et al. Hippocampus 2011, Mohapatra et al. Sci Reports 2016). The model allowed us to study activity-dependent changes of intracellular chloride concentration and their impact on synaptic inhibition.

* In my neurophilosophical musings, I am fascinated by the quandary 
whether scietific exploration of neural mechanisms of mental activity undermines our traditional understanding of personal freedom and responsibilty (Jedlicka TICS 2005)

The free man owns himself. He can damage himself with either eating or drinking; he can ruin himself with gambling. If he does he is certainly a damn fool, and he might possibly be a damned soul; but if he may not, he is not a free man any more than a dog. (Gilbert Keith Chesterton)
