Barrel cortex function

TL;DR: The role of gamma-band synchronization and NMDA receptors in cognitive functions and neuropsychiatric disorders has received increased attention over the past two decades, with significant controversy about their roles.

TL;DR: A steep sigmoidal relationship between the number of activated neurons and behaviour is found, saturating at only ~37 neurons, and this supports the sparse coding hypothesis, and suggests that cortical perception balances a trade-off between minimizing the impact of noise while efficiently detecting relevant signals.

TL;DR: In this paper, the authors analyzed synaptic strength from functionally relevant brain areas to diverse neuronal types in the primary somatosensory cortex (S1) and found that long-range projections from different areas preferentially engage specific sets of GABAergic neurons in S1.

TL;DR: During this period the rodent whisker-to-barrel cortex system shows a remarkable transition from a mostly genetic-molecular driven generation of crude connectivity, providing the template for activity-dependent structural and functional maturation and plasticity, to the manifestation of a complex behavioral repertoire including social interactions.

TL;DR: A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

TL;DR: Fundamental concepts of nonlinear microscopy are reviewed and conditions relevant for achieving large imaging depths in intact tissue are discussed.

TL;DR: This review focuses on the organizing principles that govern the diversity of inhibitory interneurons and their circuits.

TL;DR: The timing of a sensory input relative to a gamma cycle determined the amplitude and precision of evoked responses and provided the first causal evidence that distinct network activity states can be induced in vivo by cell-type-specific activation.
