Domestic chickens are members of an order, Aves, which has been the focus of a revolution
in our understanding of neuroanatomical, cognitive, and social complexity. At least some …

Much is known about the initial stages of visual processing up to the striate cortex, but how is
visual information represented and handled at subsequent stages? Phenomena of contour …

Describing feline behaviour from both a mechanistic and functional approach, this textbook
provides an accessible overview of this fascinating subject. The book begins by addressing …

We have studied the mechanism of contour perception by recording from neurons in the
visual cortex of alert rhesus monkeys. In order to assess the relationship between neural …

Although neurons in primary visual cortex are sensitive to the spatial distribution and
intensity of light, their responses have not been thought to correlate with the perception of …

This book presents an interdisciplinary overview of the main facts and theories that guide
contemporary research on visual perception. While the chapters cover virtually all areas of …

Completion of partly occluded objects is a ubiquitous phenomenon in human visual
perception. It is unclear, however, whether it occurs at all in other species: Studies on visual …

Responses to subjective contours in visual cortical areas V1 and V2 in adult cats were
investigated by optical imaging of intrinsic signals and single-unit recording. Both V1 and V2 …

This review article illustrates that mammals, birds and insects are able to perceive illusory
contours. Illusory contours lack a physical counterpart, but monkeys, cats, owls and bees …

The great increase in the study of dog cognition in the current century has yielded insights
into canine cognition in a variety of domains. In this review, we seek to place our enhanced …
