Existence and stability of persistent states in large neuronal networks

Phys Rev Lett. 2001 Apr 30;86(18):4175-8. doi: 10.1103/PhysRevLett.86.4175.


We study the existence and stability of persistent states in large networks of quadratic integrate-and-fire neurons. The networks consist of two populations, one excitatory and one inhibitory. The stability of the asynchronous state is studied analytically. Our study demonstrates the role of recurrent inhibition and inhibitory-inhibitory interactions in stable persistent activity in large neuronal networks.
