Visual System

Welcome to Andrzej Wróbel site

topics

Research of our group concerns cognitive mechanisms of brain function. Its aim is to understand the dynamic operations within sensory systems of behaving animals and humans. Using electrophysiological recording techniques and neuroinformatic methods for data analysis we are trying to correlate the specific activation of known neuronal networks with their behavioural context.
There are few parallel projects under investigation:

Electrophysiological correlates of visual attention in cat

The role of the EEG beta frequency band in attentive vision – temporal analysis (frequency, phase and amplitude’s envelope) of local field potentials registered from different parts of cat’s thalamo-cortical system during behavioral task based on intermingled trials of delayed spatial discrimination of visual or auditory stimuli.

Cognitive functions of the human brain

Electrophysiological (EEG) and bold (fMRI) correlates of attention and working memory. The validation of neurofeedback-EEG method.

Information processing in the cortico-thalamic sensory systems

  • the role of primary and secondary sensory pathways in different behavioral situations;
  • the role of thalamic and cortical inhibition in different behavioral situations;

In cooperation with Laboratory of Neurobiology of Vision (homepage)

  • the role of extrageniculate visual pathway
  • plasticity and rehabilitation in the visual system following lesions

In cooperation with Neuroinformatics Laboratory (homepage)

  • computational and theoretical studies of models of cortico-thalamic loops in visual and somatosensory systems;
