Birds are excellent model organisms to study perceptual categorization and concept
formation. The renewed focus on avian neuroscience has sparked an explosion of new data …

Most theories of how human cognition is unique propose specific representational
capacities or biases, often thought to arise through evolutionary change. In this Perspective …

Numerical cognition is ubiquitous in the animal kingdom. Domestic chicks are a widely used
developmental model for studying numerical cognition. Soon after hatching, chicks can …

Mammalian sleep has been implicated in maintaining a healthy extracellular environment in
the brain. During wakefulness, neuronal activity leads to the accumulation of toxic proteins …

Corvids possess cognitive skills, matching those of nonhuman primates. However, how
these species with their small brains achieve such feats remains elusive. Recent studies …

The ability to group abstract continuous magnitudes into meaningful categories is cognitively
demanding but key to intelligent behavior. To explore its neuronal mechanisms, we trained …

Our view of neural oscillations is currently changing. The dominant picture of sustained
oscillations is now often replaced by transient oscillations occurring in bursts. This …

Many cognitive neuroscientists believe that both a large brain and an isocortex are crucial
for complex cognition. Yet corvids and parrots possess non-cortical brains of just 1–25 g …

Noting that some theropod dinosaurs had large brains, large grasping hands, and likely
binocular vision, paleontologist Dale Russell suggested that a branch of these dinosaurs …

The nidopallium caudolaterale (NCL), an integration centre in the telencephalon of birds,
plays a crucial role in representing and maintaining abstract categories and concepts …
