Complex Dynamics Enabled by Basic Neural Features
(2020-06-12)In this thesis we aimed at understanding the fundamental properties of features commonly used in models of theoretical neuroscience from a dynamical systems' perspective. Dynamical system theory was developed while studying ... -
Revealing structure in vocalisations of parrots and social whales
(2018-08-06)This thesis proposes methods to investigate structure in bioacoustic signals. For this two frameworks are proposed. The first concerns the automatic annotation of audio recordings by using supervised machine learning ... -
Evolutionary dynamics in changing environments
(2018-06-12)Evolution can be understood as an optimization mechanism on the fitness function, which is defined as the reproductive success of a species. If the environmental conditions remain constant, the stationary states of the ... -
Network Formation and Dynamics under Economic Constraints
(2018-03-26)Networks describe a broad range of systems across a wide variety of topics from social and economic interactions over technical infrastructures such as power grids and the internet to biological contexts such as food webs ... -
Investigation of voltage- and light-sensitive ion channels
(2016-08-09)In this work, the properties of ion channels in biological membranes are characterized. Two systems are investigated: The conductance changes of the membrane of the axon initial segment (AIS) due to fast sodium channels, ... -
Neuronal mechanisms of odor classification in the Drosophila antennal lobe: an optical imaging study
(2015-12-15)Drosophila senses diverse kinds of olfactory stimuli in the external environment. These stimuli are often not pure chemicals, but rather mixtures of many odorants. The fly olfactory system, however, needs to extract the ... -
Computational modeling of neuronal circuits: heterogeneous connectivity and nonlinear transformation in olfactory processing
(2015-05-05)The first processing circuit in the olfactory system (antennal lobe or olfactory bulb) exhibits several astonishing nonlinear features, but how these characteristics emerge collectively in olfaction remains an open question. ... -
Dynamic fitness and horizontal gene transfer in stochastic evolutionary dynamics
(2013-03-12)The evolution of species is shaped by processes such as selection, mutations or genetic drift. Still, we are far away from a complete understanding of how these processes drive evolutionary dynamics in detail. Therefore, ... -
Universal Computation and Memory by Neural Switching
(2011-10-21)Complex heteroclinic networks of connected saddle states persistently emerge in a broad range of dynamical systems and may reliably encode ``memory items'' as specific switching trajectories. ... -
Topological Optimization in Network Dynamical Systems
(2011-04-05)In this thesis we look at results concerning two separate topics.The first topic belongs to the general problem of reconstruction of interaction networks using only per-site information. ...
