New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
Purkinje cells of the cerebellum, a conserved vertebrate brain region important for sensorimotor integration, receive sensory and motor information from distinct input streams and are functionally clustered into modules reflecting the larval zebrafish's behavioral repertoire.
An accurate, robust, and lightweight technique for measuring eye movements in mice was developed using magnetic sensing, yielding the first high resolution recordings of eye movements in freely moving mice.
The connectivity structure of a nociceptive circuit is precisely maintained over Drosophila larval development through cell type-specific increases in synaptic contacts as measured from electron microscopy reconstructions, while individual neurons grow five-fold in size and number of synapses.
Simultaneous 2-photon imaging of striosomes and matrix in mice shows that striosomes preferentially encode reward-predicting cues whereas both striatal compartments demonstrate reward-related activity.
Pronounced cerebellar activation during unexpected omission of a potentially harmful event suggests that the cerebellum has to be added to the neural network processing prediction errors underlying emotional associative learning.
