Background:

  • Higher-level cognitive functions, including figure-ground segregation, object recognition, selective focal attention, and awareness, pose a significant challenge to neuroscience.
  • Understanding the neural basis of these complex cognitive processes requires bridging the gap between neuronal/synaptic mechanisms and macroscopic cognitive phenomena.

Purpose of the Study:

  • To investigate how higher-level cognitive functions can be implemented at the level of synapses and neurons.
  • To explore the potential of neural plausible models in explaining complex cognition.
  • To bridge theoretical insights from connectionism and computational neuroscience with empirical observations.

Main Methods:

  • Theoretical studies utilizing neural plausible models.
