Hippocampal sharp-wave sequences, which are considered the key phenomenon underlying consolidation of episodic memory, are preserved even after an animal’s memory is impaired.

When memorising dynamic visual objects, the brain codes for both the past and the anticipated future object location and co-activates both codes when selecting memories for guiding behaviour.
Nuanced changes in the mechanism of oscillation in reciprocally inhibitory circuits can profoundly alter the circuit stability in response to perturbations and inputs.
Neurite geometry enables expansive and highly-branched neuronal structures to operate like single electrical compartments and simple linear integrators.

Mapping spike patterns from a small identified circuit reveals the diversity and complexity of circuit dynamics across animals and in response to perturbations.

V1 damage impairs unconscious following movements of stimulus motion, even after conscious perception has been restored through psychophysical training, thus demonstrating distinct neural pathways for perception and action.
Despite evidence of retinal stretching with eye growth, cone photoreceptor sampling density in the foveal center of humans actually increases with eye length.
Computational models demonstrate that circuit resilience to temperature perturbations are associated with smooth transitions between cellular mechanisms as the contributions of different currents are altered while activity is maintained.
