Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Area of Science:

  • Computational Neuroscience
  • Systems Neuroscience
  • Neurodynamics

Background:

  • Neuronal network dynamics can exhibit distinct stable states, including pathological synchrony and uncorrelated activity.
  • Synaptic plasticity plays a crucial role in shaping neuronal connectivity and network function.
  • Understanding how to modulate these dynamics is key for treating neurological disorders.

Purpose of the Study:

  • To investigate if synaptic connectivity can be reshaped by modulating neuronal dynamics.
  • To explore the effects of different stimulation protocols on network states.
  • To assess the potential of desynchronizing stimulation as a therapeutic strategy for neurological diseases.

Main Methods:

  • A computational modeling study incorporating synaptic plasticity with symmetric spike-timing characteristics.
  • Simulating a population of bursting neurons interacting via chemical synapses.
  • Applying low-frequency periodic pulse train stimulation and multi-site coordinated reset stimulation.

Main Results:

  • Coexistence of stable dynamical states: pathological synchrony and uncorrelated activity.
  • Low-frequency stimulation induced pathological learning (kindling).
  • Desynchronizing stimulation achieved long-term anti-kindling, unlearning pathological synaptic interactions, even with weak stimuli.

Conclusions:

  • Synaptic connectivity can be effectively reshaped by modulating neuronal dynamics.
  • Desynchronizing stimulation, like coordinated reset, shows promise for treating neurological diseases associated with pathological brain synchrony.
  • This approach offers a novel therapeutic avenue for conditions such as epilepsy and Parkinson's disease.
