This lesson provides an overview of balanced excitatory-inhibitory (E-I) networks, stability, and gain modulation. 

Topics covered in this lesson
  • Rate models
  • Selectivity
  • Gain modulation
  • Irregular firing and nonlinear gain modulation, loosely balanced networks
  • Going from matrix notation of neurons and inputs to rate models
  • Eigenvectors and eigenvalues of the weight matrix
  • Stability
  • Shur transformation
Prerequisites
  • Linear algebra (matrices, eigenvalues, eigenvectors)
  • Some knowledge of dynamical complex systems theory
