Practical Project – Experimental Neuropsychology
The Neuropsychology Lab offers practical projects for a maximum of six students. All projects are suitable for a Master’s thesis project as well. It is advisable that a Master’s thesis project is linked to a practical project, by method, concept, or both. Please approach us if you wish to discuss a project, also if it is not listed below. For the winter semester 2014-15 the following projects are offered.
Help brain-computer interface illiterates to learn motor imagery using new rich feedback
A significant portion of individuals cannot control brain-computer interfaces (BCI) and understanding this “BCI illiteracy” problem is a fundamental challenge. Based on our recent simultaneous EEG-fMRI motor imagery results we will investigate this issue further and predict that otherwise illiterate individuals can learn to control a BCI by using our new, optimized feedback signal.
Using a robotic hand to study the senses of ownership and agency
The sense of agency refers to the experience of controlling an action whereas the sense of ownership describes the feeling that an individual’s body part is their own. Since both concepts are of increasing interest in clinical neuropsychology we want to investigate them further by using humanoid rubber hands to induce perceptual illusions, such as the rubber hand illusion, the supernumerary limb illusion or the phantom limb illusion, or by controlling robotic hands by thought alone.
An investigation of the relationship between occipital alpha and visual evoked response
(Collaboration with Experimental Psychology Lab)
A previous simultaneous EEG/fMRI study suggested that visual information processing depends on the phase of ongoing alpha oscillations at stimulus onset. In the current practical project we will replicate this study with state-of-the –art simultaneous EEG/fNIRS technology.
The influence of selective attention on the auditory steady state response
We aim for a selective spatial auditory attention neuro-feedback protocol using the auditory steady-state response (ASSR) evoked by continuous fluctuating 'speech-like' stimuli. To better understand the influence of selective attention on the ASSR the practical project will investigate attention effects at a fundamental level and the relationship between attention effects and stimulation rate.
Auditory dynamic attending in a multisensory context
It is known that our auditory system uses environmental rhythms to predict and anticipate forthcoming sensory input, leading to preferential processing of events occurring at predicted times, but the extent of this phenomenon is not well understood. We will investigate whether the auditory system can also extract rhythms from non-auditory input, such as visual or tactile.
Audio-visual processing and cross-modal plasticity in Cochlear-Implant-Users
Cortical reorganization following cochlear implantation (CI) is necessary to adapt to the implant and restore hearing in otherwise deaf people, but the capacity for adaptation may interact with sensory deprivation-induced cortical reorganization. In a recent study we found evidence for altered face processing in CI users, and we want to further investigate this result and the audio-visual integration capabilities in CI users (e.g. the McGurk effect).
