Research focus: My research activity is inserted in the field of Neuroengineering

Research focus: My research activities are in the field of the neuroengineering and they include both experimental and theoretical aspects. In particular, I am working on dynamics exhibited by large-scale networks.

Research focus: Visual object recognition and executive control of goal-directed behavior in non-human primates. Also high-resolution fMRI of human cortical functions.

Research focus: How the brain realizes reinforcement learning.

Research focus: My goal is to examine how cortical neurons encode sensory stimuli and how stimulus representation is affected by behavior. using in vivo electrophysiology and 3D reconstruction of recorded neurons.

Research focus: Next generation CoCoMac database (Macaque Monkey anatomical connectivity data)

INCF activities: Digital Brain Atlasing | Digital Atlasing Infrastructure Task Force

Research focus: Structural and functional connectivity of neural networks in the rodent cortex with a focus on the somatosensory system employing electrophysiological and neuroanatomical in vitro approaches.

Research focus: Modeling and analysis of Local Field Potentials

Research focus: We are studying information processing in thalamo-cortico-thalamic loops in mammal sensory systems concentrating on the visual system of the cat and the somatosensory system of the rat. In particular we are interested in mechanisms of context-dependent modulation of information processing.   To achieve our goals we develop new methods of data analysis, test it on different models of the studied systems, and analyze the experimental data. We concentrate on analysis and modeling of electrophysiological data, both spike trains and local field potentials.

Research focus: Current research in the laboratory focuses on understanding dynamic operations within sensory systems of behaving animals. Using electrophysiological recording techniques and neuroinformatic methods for data analysis we are trying to correlate the activation of specific neuronal networks with its behavioral context. Five parallel projects are under investigation:   Current research activities    *   electrophysiological correlates of visual attention in cats - 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;  *   information processing in the cortico-thalamic part of the rat's somatosensory system - the role of primary and secondary sensory pathways in different behavioral situations; in vitro electrophysiological investigations of synaptic properties and cellular connections within the cortico-thalamic loop of rodent's somatosensory system;  *   the role of extrageniculate visual pathway in movement perception - electrophysiological and modeling investigations on the spatial and temporal properties of single units' receptive fields in the cat; coding of information in geniculate and extrageniculate visual pathways in the cat - electrophysiological and computational studies on temporal pattern of neuronal activity;  *   application of nonlinear and wavelet methods for time series analysis; theoretical studies of models of cortico-thalamic loops in visual and somatosensory systems; white-noise and information theoretical analysis of spike trains; development of new current source density techniques for the analysis of three dimensional data.
