The movement of animals through space filled with various objects requires the interaction
between neuronal mechanisms specialized for processing local object motion and those …

The retinal image changes that occur during locomotion, the optic flow, carry information
about self-motion and the three-dimensional structure of the environment. Especially fast …

In many situations animals are confronted with approaching objects. Depending on whether
the approach represents a potential threat or is intended during a goal-oriented approach …

Optokinetic responses function to maintain retinal image stabilization by minimizing optic
flow that occurs during self-motion. The hovering ability of hummingbirds is an extreme …

Neurons in animal visual systems that respond to global optic flow exhibit selectivity for
motion direction and/or velocity. The avian lentiformis mesencephali (LM), known in …

The superior colliculus (SC) in the mammalian mesencephalon is involved in avoidance or
escape behaviors, but little is known about the response properties of collicular neurons to …

Although the optic tectum in non‐mammals and its mammalian homolog, the superior
colliculus, are involved in avoidance behaviors, whether and how tectal neurons respond to …

The nucleus of the basal optic root (nBOR) of the accessory optic system (AOS) and the
pretectal nucleus lentiformis mesencephali (LM) are involved in the analysis of optic flow …

The pretectal nucleus lentiformis mesencephali (LM) and the nucleus of the basal optic root
(nBOR) of the avian accessory optic system (AOS) are retinal-recipient visual nuclei involved …

The tectofugal pathway in birds goes from the optic tectum to the telencephalic entopallium
via the thalamic nucleus rotundus (nRt). This pathway may be homologous to the colliculo …
