Barrel cortex function

TL;DR: The origins of the PTs’ ability to respond to a broad range of stimuli with onset latencies that rival or even precede those of their intracortical input neurons are reported.

TL;DR: In a computer model, the hypothesis that sensory representations in L1/3 of the rodent barrel cortex are formed by activity propagation horizontally within L2/3 from a site of initial activation is tested.

TL;DR: Levitan and Gilad study neuronal dynamics in cortex and amygdala as mice learn a sensory discrimination task and find that amygdala areas display opposing responses only after the mice learn the task, implying that learning induces an involvement of amygdala and cortical areas in order to optimally link sensory stimuli with appropriate associations.

TL;DR: It is strongly indicated that whisker trimming affected Orient, but not the reaching-grasping movement, while ION severing impaired both Orient (persistently) and reaching- Grasping-retracting (transiently, for 1–2 weeks) components of skilled reaching in rats.

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.
