| Open AccessEfficient coding of natural images in the mouse visual cortex
Whether mice can perceptually discriminate between texture images, and if so how these stimuli are processed by their visual system, remains an open question. Here, the authors show that mice can visually discriminate between textures and found evidence for ‘efficient coding’, highlighting a correlative link between image statistics, perceptual behavior, and geometrical aspects of neural representations.

| Open AccessSilencing CA1 pyramidal cells output reveals the role of feedback inhibition in hippocampal oscillations
Current approaches possibly cannot unambiguously distinguish the unique contributions of feedback inhibition versus feedforward inhibition to oscillatory events. Here authors show that a loss of CA1 pyramidal cell transmission, resulting in feedback inhibition reduction, leads to spatially triggered high-frequency oscillatory events; these events were like place cells in their spatial extent and localized to small regions in CA1.
