Adaptation und Aufmerksamkeit in higher visual perception
(2010-04-29)Seeing, at its simplest, is merely the registering of light and some reaction to it. Primate visual perception is not only a passive, feedforward absorption of information of the surrounding ... -
Auditory associative learning and its neural correlates in the auditory midbrain
(2021-01-08)Interpreting the meaning of environmental stimuli to generate optimal behavioral responses is essential for survival. Simply sensing a sound, without accessing prior knowledge in the brain, will not benefit behavior. How ... -
Central sound encoding in the inferior colliculus of mouse models for human auditory synaptopathy and neuropathy
(2018-12-20)Auditory neuropathy and auditory synaptopathy are hearing disorders with normal outer hair cell function and cochlear amplification, but an impairment in the function of inner hair cells, their ribbon synapses, or in the ... -
Eye, hand and space representations and causal interference in bihemispheric pulvinar-parietal circuitry
(2019-05-29)Recent research proposes that a proper action is the outcome of continuous competition between multiple frontoparietal neuronal representations of possible response options and this competition is biased by the input ... -
How nonlinear processing shapes natural stimulus encoding in the retina
(2022-05-31)Understanding natural vision is one of the fundamental goals of sensory neuroscience. The only part of the visual system that may currently be amenable to such a complete understanding is the vertebrate retina, where there ... -
Imaging Network Alterations in Patients With Genetic Generalized Epilepsy and Their Healthy Siblings Using Magneto- and Electroencephalography
(2022-04-05)Genetic generalized epilepsy (GGE) is a common epilepsy syndrome and represents the largest group of epilepsies suspected to have a complex genetic etiology. Specific time windows for age of onset and various seizure types ... -
Information Processing Analysis in Neural Networks
(2019-06-06)Populations of cortical neurons in the fluctuation-driven regime exhibit an ultrafast population response. Some theoretical studies suggest that passive, morphological features of the axon and dendrites determine the ... -
Methodological and Cognitice Aspects of transcranial Electrical Stimulation
(2017-04-06)Transcranial electrical stimulation (tES) techniques are based on the external application of low-intensity electrical current to the brain. The external current can modulate cortical excitability by depolarizing or ... -
Neural basis of rule-based decisions with graded choice biases
(2016-07-22)In every hour of every day we are faced with options; which route to take to work, where to go for a meal, which stocks to invest in. However, with limitations of movement, time and budget, our options are constrained. We ... -
Neural coding of grasp force planning and control in macaque areas AIP, F5, and M1
(2016-10-27)Much research has been done in the last decades to decipher how the brain controls grasping movements. The anterior intraparietal area (AIP), the hand area of the ventral premotor cortex (F5), and the hand area of the ... -
Neural population dynamics and frontal-parietal circuit for context-dependent sensorimotor computations
(2020-05-27)This dissertation investigated the computational strategies in the primate's brain for goal-directed movement control and the information stream in inter-areal brain circuits. The animal model used in this research was ... -
Neuron-level dynamics of oscillatory network structure and markerless tracking of kinematics during grasping
(2021-11-18)Oscillatory synchrony is proposed to play an important role in flexible sensory-motor transformations. Thereby, it is assumed that changes in the oscillatory network structure at the level of single neurons lead to flexible ... -
Neuronal mechanisms of the adaptation of conditional visuomotor behavior
(2011-10-20)Goal directed movements are guided by sensory inputs, which define the spatial constraints for such movements. Our vision, and also our other senses, give us information about the location ... -
Representation of individual finger movements in macaque areas AIP, F5 and M1
(2019-05-21)The goal of this study was to investigate how individuated finger movements are coded in area AIP, F5 and M1. At the single neuron level, most of the units in all three areas were “broadly tuned”, responding during multiple ... -
Simulation of fronto-parietal neural population activity to probe dimensionality reduction methods.
(2022-09-20)Recent developments of optical and electrophysiological recording tools allow the detailed capture of large neuronal populations. Findings show that their activity is constrained to a low-dimensional manifold within the ... -
Spatial, feature and temporal attentional mechanisms in visual motion processing
(2013-06-27)The three projects documented in this thesis investigated the role of three forms of attention in visual processing. Spatial, feature-based and temporal attention. The spatial and feature-based attentional characteristics ... -
The impact of reward value on early sensory processing and its interaction with selective attention
(2021-11-22)Reward value affects the earliest stages of sensory perception. Whereas a host of previous studies have investigated the underlying mechanisms of reward-driven modulation of visual perception, reward effects in other sensory ... -
The influence of attention on motion processing
(2013-10-25)This thesis examined the influences of attention on the processing of complex and simple motion stimuli. The work consists of two physiology studies. In the first study we investigated the question of how complex motion ... -
The influence of attention on the processing of transparent motion in primate visual cortex
(2011-08-18)The scope of this thesis is centered on the question of how attention influences the processing of visual information. Hereby, the highly-developed ability of primates to process visual ... -
The Principles of Self-Organization of Memories in Neural Networks for Generating and Performing Cognitive Strategies
(2018-12-12)Higher-order animals exhibit the remarkable ability to dynamically adapt to a changing environment. On the neuronal level, they have to form mental representations of specific stimuli, so-called memories. Furthermore, ...
