The Neuropharmacological Basis of Attention in Rhesus Macaques
(2025-03-07)This thesis aimed at unraveling the neuropharmacological basis of attention in rhesus macaques, focusing on the involvement of different neurotransmitter systems. Attention, as a selective filtering process, is crucial ... -
Perceptual Misbinding of Color and Motion - Visual Feature Integration in Humans and Macaques
(2025-02-24)To interact with our environment, sensory signals must be translated into perceptions that guide our behavior. However, our noisy, crowded, and dynamic environment provides too much information to process. As a result, our ... -
Neural correlates of action effects anticipation – towards ecological more relevant paradigms
(2023-12-07)Imagine it is Saturday morning and you are going for groceries with your car. Once you arrive at the supermarket, you attempt to reverse park your car in a narrow parking space. You have learned in school, if you want ... -
Neural representation of complex motion in the primate cortex
(2021-11-04)This dissertation is concerned with how information about the environment is represented by neural activity in the primate brain. More specifically, it contains several studies that explore the representation of visual ... -
Neural correlates of conscious visual processing
(2021-06-01)The objective of the current thesis is to evaluate the role of alpha band activity and neural trial-to-trial variability in conscious visual perception and their relationship to each other. We investigate these measures ... -
Receptive Field Characterization in MSTd Neurons
(2018-12-14)The dorsal region of the medial superior temporal area (MSTd) in primate extrastriate visual cortex is reported to play a major role in the encoding and perception of optic flow stimuli, i.e. large-scale motion patterns ... -
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 ... -
Visual information processing, welfare, and cognition in the rhesus macaque
(2017-10-20)Visual information processing, welfare, and cognition in the rhesus macaque - Chapter one deals with motion and disparity in macaque monkeys' area MST and their functional independence. Chapter two relates with the advantages ... -
Neuronal representation and attentional modulation of space and feature information in primate vision
(2017-10-17)Visual perception lays the groundwork for many activities of animals and human. Decades of neuroscience research in vision also revealed much knowledge about the general computational principles of the brain. My dissertation ... -
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 ... -
Neuronal correlates of implicit learning in the mammalian midbrain
(2016-08-29)Filtering auditory information according to its relevance is critical to elicit the appropriate behavioral response. The relevance of a sound is not carried by the sound itself but rather assigned by the brain based on ... -
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 ... -
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. ... -
Reference frames for planning reach movement in the parietal and premotor cortices
(2016-02-16)Human and nonhuman primates are able to plan and execute goal-directed behavior and flexibly respond to their surrounding stimuli. Their ability to adapt to changes in their environment is a crucial factor for their ... -
From vision to action: Hand representations in macaque grasping areas AIP, F5, and M1
(2014-12-19)Grasping and manipulating objects of different shapes is a fundamental feature of the primate hand. This skill requires the transformation of visual object information into corresponding hand actions. In the primate brain ... -
Attention modulation of complex motion patterns in human visual cortex
(2014-12-12)When we are moving through the environment, our visual system exposes to a barrage of motion information about the objects around us as well as our own heading. Processing such an amount of incoming sensory data is beyond ... -
An Exploration of Real-Time Functional Magnetic Resonance Imaging Neurofeedback in Cognition
(2014-10-31)This thesis deals with an extensive exploration of the use of rt-fMRI neurofeedback in cognition. Specifically, the work presented here comprises the major steps in the development of a suitable experimental framework for ... -
The somatosensory system: Exploration of digit-area somatotopy and feature-based attention
(2013-12-19)Even though the skin is by far the largest sensory organ that we humans possess and immensely important for coping with everyday life, the somatosensory system has been studied far less than the visual or auditory system. ... -
Modeling the origins of spatial and temporal variability in visual cortical representations
(2013-11-25)Response characteristics of orientation-tuned neurons in the visual cortex appear to be similar in mammalian lineages widely separated in evolution. The spatial arrangement of preferences across the cortex, however, shows ... -
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 ...
