Research in the laboratory 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 atention 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) correlates of attention and working memory.Information processing in the cortico-thalamic part of somatosensory system
- investigations on context-dependent gating of the sensory information at the cortico-thalamic level of the whisker-barrel system of the rat;In cooperation with Neuroinformatics Laboratory (homepage)
- the role of primary and secondary sensory pathways in different behavioral situations;
- the role of thalamic inhibition in different behavioral situations;
- the role of fast oscillations in cortical somatosensory information processing.
- development and application of analytical methods for time series analysis;In cooperation with Laboratory of Neurobiology of Vision
- computational and theoretical studies of models of cortico-thalamic loops in visual and somatosensory systems;
- reconstruction of three-dimensional brain structures based on 2D histological atlases.
- the role of extrageniculate visual pathway
- plasticity and rehabilitation in the visual system following lesions
