Research Goals:

  • The Affective Neuropsychology Group studies: 
  • Emotional processing in humans 
  • Its underlying neural mechanisms

Interests: 

  • The influence of emotions on attention and memory processes modulation
  • Communicative aspects of emotions in the processing of language and faces 
  • The role of emotions in man-machine interactions
Faces

Study Focus:

  • Typical processes in healthy people 
  • Atypical processes as observed in neurological and psychiatric disorders 

Objectives: 

  • Gain a comprehensive understanding of emotional processing
  • Especially of residual brain functions in patients with severe brain injuries (unresponsive wakefulness and minimal consciousness state) and in developing ways to improve their disease-course with emotional stimulation

Cooperations:

  • Epilepsy Clinic Mara  
  • House Elim within the Bethel institution. 
  • CITEC groups: Neuroinformatics group, Computer Graphics. 
  • Several other national and international collaborations

Interested in exploring the brain artistically?

Example EDGE Art

In order to make neuroscience more accessible and to explore new ways of communicating state-of-the-art scientific discoveries, our lab actively participates in the science communication association EDGE Neuroscience and Art e.V. EDGE is an international collective of artist-scientists dedicated to the study of neuroscience. The association builds a harmonious synergy between art and science within and outside the community of EDGE. Our lab member Enya is leading the EDGE West chapter, bringing EDGE from Berlin and the US to North-Rhine Westphalia (NRW). Visit the website to learn more about past and upcoming events, exhibitions, and workshops: edge-neuro.art

Single Electrode

Research Methodology

  • Electroencephalography (EEG),
  • Functional Magnetic Resonance Imaging (fMRI)
  • Behavioural measures. 

Laboratories

  • Several behavioural and EEG-labrooms

The Work in Electroencephalographical (EEG) Labs:

  • Measuring electric brain activity by means of sensors
  • Background:
    • The activity of the wake human brain generates electric fields 
    • The intensity changes with different brain activities in the order of millionth parts of a volt
    • These changes are being recorded with millisecond precision.
    • For those recordings we use sensor-nets with 32 channels up to high-density with 128 channels.

Equipment: 
ActiveTwo systems by Biosemi: 

  • One 128-channel EEG-device 
  • One 32-channel EEG-device
     
  • TMSi Refa multi-channel amplifier (32 channels & 8 external electrodes & ground electrode)
  • EEG low noise cap with 32 build-in electrodes & ground electrode
