Neuronal responses in cortical area MT to two speeds show a robust bias toward the faster speed when stimulus speeds are slow, which could benefit figure-ground segregation in natural scenes.
During foraging under predatory threat, overlapping prefrontal neuron populations flexibly switch between encoding navigational space and predicting avoidance decisions.
Experiments reveal that a time-dependent epistatic interaction influences how mice respond to opioids, and that intracellular fibroblast growth factors also influence opioid sensitivity.
Feedback signals to the early visual cortex convey both high-order and low-order visual information, but with different laminar profiles, and the high-order information is important for object recognition.
