Improving Cognition in Older Adults Through Transcranial Electrical Stimulation And Cognitive Training
(2024-07-23)The progressive aging of the global population continues unabated. Consequently, there is a substantial increase in the prevalence of neurocognitive disorders, primarily observed in the elderly. Current pharmacological ... -
Developing tools for translational In-vivo cochlear optical stimulation
(2024-07-02)Utilizing optogenetic stimulation to target type I spiral ganglion neurons (SGNs) could promise an alternative to the currently employed electrical stimulation by current cochlear implants (CIs). Given light's spatial ... -
The Role of the Transient Receptor Potential Vanilloid 1 (TRPV1) Channel in Sharp Wave Ripples, Place Cells, and Spatial Memory
(2024-02-09)Previous research in our lab found impaired long-term potentiation (LTP) of CA3-CA1 synapses, a fundamental process for learning and memory, in transient receptor potential vanilloid 1 (TRPV1) knockout (KO) mice. The TRPV1 ... -
The role of pulvinar-parietal circuitryin goal-directed saccades
(2023-11-28)The pulvinar, an important higher-order thalamic nucleus supporting many functions, is reciprocally connected with frontoparietal areas involved in sensorimotor transformations. Priorperturbation studies also revealed its ... -
Functional Decomposition of Retinal Ganglion Cell Receptive Fields
(2023-02-23)The retina has the fascinating ability to extract various visual features from our surroundings. This feature detection is enabled by nonlinear operations in the retinal circuitry. The nonlinear processing is in part ... -
Mechanisms of local and global motion detection in Drosophila
(2021-07-06)Visual motion is an essential cue for many sighted animals. This can either be caused by the movement of an object, or the relative movement of the entire world caused by self-motion of the animal. Accordingly, the brain ... -
Control of primate prehension in space and time
(2021-05-11)Prehension in primates allows diverse interactions with the environment. It can be separated into two processes: the transport of the arm to the object, termed reach, and the getting hold and manipulation of the object, ... -
Monkey see, monkey touch, monkey do: Influence of visual and tactile input on the fronto-parietal grasping network
(2020-06-12)One of the most common movements we do every day is grasping. Usually we do this with aid of our eyes, but other senses, like our sense of touch, can also assist in the preparation and execution of grasping movements. More ... -
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 ... -
Decoding Cortical Motor Goal Representations in a 3D Real-World Environment
(2018-10-10)In sensorimotor neuroscience a certain motor behavior, and its underlying neuronal mechanism, is usually studied in isolation and tightly constrained by the experimental setting to provide interpretable results. When ... -
The role of attention and adaptation in shaping cortical representations and the perception of abrupt changes in the visual environment
(2017-11-22)The visual system receives a wealth of visual information about objects with changing features in time. Attention is a mechanism allowing us to prioritize the processing of relevant information at the expense of other ... -
Untangling neuronal diversity: a quantitative electrophysiological and morphological characterization of VIP expressing interneurons
(2017-03-21)VIP expressing interneurons are an essential component of cortical circuitry. This distinct subgroup of inhibitory interneurons was always described as the most heterogeneous subgroup of inhibitory interneurons. However, ... -
Towards population coding principles in the primate premotor and parietal grasping network
(2017-01-03)As humans, the only way for us to interact with the world around us is by utilizing our highly trained motor system. Therefore, understanding how the brain generates movement is essential to understanding all aspects of ... -
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 ... -
The neuropharmacology of attentional modulation in primate visual cortex
(2016-09-30)This thesis aims to shed light on the mechanisms of spatial attention, a selective process allowing prioritizing spatial locations in the visual field, on a psychophysical as well as on a perceptual level. The first and ... -
Feature-based attention in primate visual cortex
(2016-07-06)The scope of this thesis, after a brief summary of the core ideas of top-down attentional control is given (Chapter 2.1), is to shed some light on the cortical control circuit underlying the deployment of feature-based attention. ...
