The aim of the Center for Translational Neurophysiology of Speech and Communication CTNSC@UniFe is twofold. On one side we are studying how the brain builds communicative and linguistic representations. On the other side we are designing new brain interfaces, specifically conceived for human use, to record and computationally decode neural signals. A particular focus of the Center is on communication because we believe that many paralyzing pathologies require, at first, the restoring of an efficient communicative flow between the patient and the environment.
To this purpose we are studying the way by which the brain processes and understands the communicative behaviors of other individuals in order to efficiently decode the brain signals related to communicative intentions, we are applying innovative and possibly biologically-compatible technologies to the problem of automatic speech and action recognition (Speech and Communication Team) and we are designing a new generation of brain electrodes characterized by reduced invasiveness, improved resolution and sensitivity (Neural Interfaces Team).
In summary, with a critical focus on translational methodologies (single unit recordings, Micro-ECoG, fMRI, EEG, TMS), our research goal is to advance knowledge on brain functioning to help building the next generation of brain-computer interfaces. The group research activities span from basic research to applied one along three main research lines:
- Design of long-term and stable neural-tissue interfaces
- Research on brain centers and circuits involved in action/speech understanding
- Research on new efficient methods for automatic speech recognition
Collaborations with other National and international labs are fundamental. A particularly intense collaboration is running between CTNSC@UniFe and the Neurosurgery Unit of Udine Hospital (M. Skrap).
CTNSC@UniFe hosts state-of-the-art facilities for motion capture, neurophysiology, histology, cell culture, material science, electrochemical and electrical characterization.
- Neuronavigated Transcranial Magnetic Stimulation, High density Electroencephalography, Eye-tracking, Optical Motion Tracking and ElectroMagnetic Articulography
- Tethered and wireless multichannel neural recording and stimulation, Neuron Tracing Fluorescence Microscopy, Histology Sectioning Microtome, Primary Cells Culture facilities
- Galvanostats/Potentiostats, Chemical Synthesis and Polymerization, High Resolution Optical Microscopy, LCR meter, Electrometer, Dual Source Meter
The aim of the research line in Multiscale Brain Communication, within the CTNSC@UniFe, is twofold. On one side we are studying how the brain builds communicative and linguistic representations. On the other side we are designing new brain interfaces, specifically conceived for human use, to record and computationally decode neural signals. A particular focus of our line is on communication because we believe that many paralyzing pathologies require, at first, the restoring of an efficient communicative flow between the patient and the environment.
