The anatomy of the mammalian visual system, from the retina to the neocortex, is organized
hierarchically 1 . However, direct observation of cellular-level functional interactions across …

Brain rhythms are activity fluctuations shared in populations of neurons. They are evident in
extracellular electric fields and detectable through recordings performed within the brain or …

The gamma frequencies of the local field potential (LFP) provide a physiological correlate for
numerous perceptual and cognitive phenomena and have been proposed to play a role in …

Gamma components of the local field potential (LFP) are elevated during cognitive and
perceptual processes. It has been suggested that gamma power indicates the strength of …

Neuronal responses are correlated on a range of timescales. Correlations can affect population
coding and may play an important role in cortical function. Correlations are known to …

The visual cortex is hierarchically organized, yet the presence of extensive recurrent and
parallel pathways make it challenging to decipher how signals flow between neuronal …

Structural rules underlying functional properties of cortical circuits are poorly understood. To
explore these rules systematically, we integrated information from extensive literature …

Neural activity in the gamma frequency range (“gamma”) is elevated during active cognitive
states. Gamma has been proposed to play an important role in cortical function, although this …

The brain consists of many cell classes yet in vivo electrophysiology recordings are typically
unable to identify and monitor their activity in the behaving animal. Here, we employed a …

Cortical circuits can flexibly change with experience and learning, but the effects on specific
cell types, including distinct inhibitory types, are not well understood. Here we investigated …
