Barrel cortex function

TL;DR: A digital model of the rat facial nucleus anatomy is constructed and morphological cell-to-cell variably within a population of motoneurons that innervate the same muscle is quantified.

TL;DR: A large network of integrate-and-fire neurons with several salient features of neuronal populations in the rat barrel cortex is proposed and studied, demonstrating a possible mechanism for how the stimulation of a single neuron translates into a signal at the population level, which is taken as a proxy of the animal’s response.

TL;DR: These findings indicate that the temporal sharpening of sensory‐evoked activity coincides with the onset of active whisking.

TL;DR: It is demonstrated that activity-driven BDNF’s effects on circuits formed by the layer IV spiny stellate cells are highly specific and postulate that the role of activity-dependent BDNF is to modulate the computational ability of circuits that relate to the gain control (i.e., feed-forward inhibition); whereas the basic wiring of circuits relevant to the sensory pathway is spared.

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.
