INTEGRATIVE NEUROPHYSIOLOGY GROUP

Integrative Neurophysiology

The Integrative Neurophysiology group aims to discover emergent phenomena from neuronal systems in the brain and the spinal cord.

In particular, we analyze the electrical and hemodynamic activity of populations of neurons from the cerebral cortex, cerebellum, brainstem, and spinal cord. We integrate the study of sensory and motor systems, including neuronal systems involved in cognitive processes. We also study the complex language between neurons that includes random signaling called “neuronal noise.”

Our findings will help to generate new knowledge about fundamental mechanisms of perception, motor action, and cognition, in functional and pathological states. They also will help to design advanced prosthetic devices to augment the functional capabilities in subjects with neuronal disorders in the brain and spinal cord. 

Our experiments are performed in acute or chronic preparations in anesthetized or decerebrate animals, but also noninvasively in the human.

 

Our Methods and Heuristic Techniques

First, we explore new questions noninvasively in the human brain or the spinal cord, and then we come back to the animal preparations to examine physiological mechanisms or vice versa.

We employ emerging technologies that are perceived as capable of changing the status quo in the studies of the spinal cord or the brain functions. We also develop new neurotechnologies to open new questions in the field of emergent phenomena from the studied neuronal systems.

Some of these neurotechnologies are Optogenetics, Multielectrode Recording, Microelectromechanical Systems (MEMS), functional NIRS, transcranial random noise stimulation (tRNS), transcranial magnetic stimulation (TMS).

 

Emergent phenomena from which our group is pioneer in the Integrative-Neurophysiology field

  • The internal stochastic resonance phenomenon in the nervous system
  • The multisensory stochastic resonance phenomenon
  • The internal multisensory stochastic resonance phenomenon
  • The phenomenon of traveling waves in the spinal cord during a rhythmical motor task
  • The post-scratching locomotion phenomenon
  • The phenomenon of pre-movement electrical potentials in unconscious decerebrate animals

 

New neurotechnologies that we developed

Optogenetic noise photostimulation (ONPS), Spinal Cord Multielectrode Matrix (SCMM), Device for detection of EEG traveling waves in the human brain, Multisensory Stimulation Device (MSD).
