In vivo recordings and computational modeling of the electrosensory lobe of mormyrid fish provide a circuit-level description of how learning generalizes to new situations.

Sensory receptors encode stimuli by transiently synchronizing ongoing electrical oscillations, conferring enhanced sensitivity to communication signals produced by large groups of conspecifics.

Building on previous work (Baker et al., 2015), further evidence is reported for a novel mechanism for sensory coding based on the detection of oscillatory synchrony among peripheral receptors.

Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.

Classical theoretical approaches to studying the cerebellar cortex are generalized to a broader set of learning tasks, revealing that the optimal value for the sparsity of granule cell activity is task-dependent.
