- 15 October 1996
It is demonstrated that large-scale network synchronization requires a critical (minimal) average number of synaptic contacts per cell, which is not sensitive to the network size, and that the GABAA synaptic transmission provides a suitable mechanism for synchronized gamma oscillations in a sparsely connected network of fast-spiking interneurons.

Mechanisms of gamma oscillations.
- G. Buzsáki, Xiao-Jing Wang
- BiologyAnnual Review of Neuroscience
- 20 June 2012
The cellular and synaptic mechanisms underlying gamma oscillations are reviewed and empirical questions and controversial conceptual issues are outlined, finding that gamma-band rhythmogenesis is inextricably tied to perisomatic inhibition.

A plethora of studies will be reviewed on the involvement of long-distance neuronal coherence in cognitive functions such as multisensory integration, working memory, and selective attention, and implications of abnormal neural synchronization are discussed as they relate to mental disorders like schizophrenia and autism.

Several mechanisms that enhance the signal-to-noise ratio in working memory states could be implemented in the prefrontal cortex by dopaminergic projections from the midbrain, using a recurrent network model of object working memory.

This picture provides a rigorous and quantitative explanation for the dependence of performance and response time on the degree of task difficulty, and the reason for which reaction times are longer in error trials than in correct trials as observed in the monkey experiment.
What determines the frequency of fast network oscillations with irregular neural discharges? I. Synaptic dynamics and excitation-inhibition balance.

This work shows how to derive quantitatively the coherent oscillation frequency for a randomly connected network of leaky integrate-and-fire neurons with realistic synaptic parameters.
The importance of mixed selectivity in complex cognitive tasks

It is shown that mixed selectivity neurons encode distributed information about all task-relevant aspects, so that each aspect can be decoded from the population of neurons even when single-cell selectivity to that aspect is eliminated.
