Modulatory effects of inhibition on persistent activity in a cortical microcircuit model

Frontiers in Neural Circuits, 2014
Neocortical network activity is generated through a dynamic balance between excitation, provided by pyramidal neurons, and inhibition, provided by interneurons. Imbalance of the excitation/inhibition ratio has been identified in several neuropsychiatric

Nonperiodic Synchronization in Heterogeneous Networks of Spiking Neurons [PDF]

The Journal of Neuroscience, 2008
Neural synchronization is of wide interest in neuroscience and has been argued to form the substrate for conscious attention to stimuli, movement preparation, and the maintenance of task-relevant representations in active memory. Despite a wealth of possible functions, the mechanisms underlying synchrony are still poorly understood.
