Pairing transcranial direct current stimulation and mindfulness meditation in the treatment of fibromyalgia
(2024-08-22)The lack of effective treatments for managing pain and associated symptoms in fibromyalgia (FM) poses both a clinical challenge and an economic burden on the health sector. Typical FM therapies include an array of ... -
Influence of Interictal Epileptiform Activity on Language Networks in Children with Rolandic Epilepsy or Dyslexia
(2024-01-05)Self-limited Epilepsy with Centrotemporal Spikes (SeLECTS) is the most common genetic epilepsy in children. It is characterized by seizures remission in puberty and highly frequent interictal epileptiform discharges (IEDs) ... -
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 ... -
The role of pulvinar during perceptual decision-making and thalamic interactions with cardiac and respiratory activity in macaques
(2023-08-22)The dorsal pulvinar (dPul), a higher-order thalamic hub, is instrumental in spatial orienting and selecting stimuli in our environment by gating cortico-thalamic-cortical communication. However, its precise role in perceptual ... -
Modulation of sensory processing under different modes of reward cueing
(2023-04-13)Rewards not only shape our value-based choices but also affect our simple perceptual decisions. Accordingly, behavioral and neural correlates of reward-driven effects on perception have already been identified at the ... -
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 ... -
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 ... -
Perceptual and motor intentional processing in dorsal pulvinar
(2019-06-27)The pulvinar is the largest thalamic structure in the center of the brain, reciprocally connected to a large diversity of cortical areas. It has grown more than other subcortical structures during primate evolution, which ... -
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 ... -
Decoding the Epigenome of Neuronal Networks in Health and Disease
(2019-05-27)Alzheimer’s disease (AD) is the most prevalent form of dementia that has vast emotional and economic implications in our society. There is no cure for this neurodegenerative disorder as the pathological changes occur years ... -
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 ... -
Pulvinar-cortical interactions for spatial perception and goal-directed actions in non-human primates
(2018-12-12)The pulvinar nucleus, the largest thalamic nucleus in primates, has been shown to be involved in goal-directed visuomotor behavior related to the contralateral side of visual space. However, there is conflicting evidence ... -
Oscillations in routing and chaos
(2017-10-09)The human brain is one of the most complex structures known to mankind, and arguably the most elaborate biological system that ever evolved. Studying such complex machinery whose precision and efficiency we witness in the ... -
Visual and Auditory Perceptual Decision-Making in The Human Brain as Invesitgated by fMRI and Lesion Studies
(2017-07-27)Perceptual decision-making refers to the act of choosing one option from a set of alternatives based on the available sensory information. In this manuscript, we used model-based functional magnetic resonance imaging and ... -
Optimizing the efficacy of transcranial direct current stimulation on cortical neuroplasticity based on a neurovascular coupling model
(2017-03-01)Transcranial direct current stimulation (tDCS) induces polarity-specific enduring alterations of cortical excitability, and activity. Cortical excitability can be monitored in a limited set of cortical areas in the human ... -
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. ... -
Neuronal basis of goal-directed reach planning under reversed vision in the parietal and premotor cortices
(2013-10-09)In our everyday life we can produce goal-directed movements precisely and effortlessly, for example to saccade towards a location that you are interested in, or to reach and grasp for a cup of coffee. Goal-directed behaviors ... -
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 ...
