Probing the link between perceptual visibility and brain oscillations

Location(s): Cognitive Neuroscience Lab, German Primate Center, Göttingen, Germany

Supervisors: Dr Wilke, Dr Kagan, Dr Treue

The goal of this project is to elucidate the causal link between conscious visual perception and neural activity in thalamo-cortical circuits with electrophysiological recordings and microstimulation in rhesus monkeys. We address the question which of the previously identified neural correlates of consciousness truly reflect the subjective experience and which are due to attention, decision and motor processes associated with active behavioural reports.

Behavioural paradigm: Active perceptual report and novel no-report paradigms on visibility/switching using binocular rivalry; cued spatial attention task to dissociate attentional effects from perceptual visibility. 

Recording and stimulation techniques: MRI-guided frequency-specific electrical microstimulation and simultaneous multi-site (laminar) spike and LFP recordings. 

Planned secondment(s):

  • Sapienza University of Rome 
  • Newcastle University (UK)
