The augmentation of resin-embedded sample blocks with magnetic resin allows remote actuation of ultrathin sections and deposition at high packing density onto silicon wafers for correlative light and electron microscopy.
The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.
Cortex dynamically regulates the flow of sensory information by suppressing responses of non-relevant stimuli through mechanisms of adaptation, while boosting sensory responses that are behaviorally important.
Independent coding without synaptic coordination explains complex sequences of population activity observed during theta states and maximizes the number of distinct environments that can be encoded through population theta sequences.
Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).
A human psychopharmacology study reveals that a drug that affects the dopamine and noradrenaline systems enhances people's ability to adapt their learning rate to suit the volatility of the environment.
