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

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 …

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 …

Neuroanatomical studies have demonstrated that the two major descending pathways from
the superior colliculus arise from regionally segregated, distinct, cells of origin. Stimulation …

Neurons in the rostral superior colliculus (SC) of alert cats exhibit quasi-sustained discharge
patterns related to the fixation of visual targets. Because some SC neurons also respond to …

Combining the results of behavioral, neuronal immediate early gene activation, lesion and
neuroanatomical experiments, we have presently investigated the role of the superior …

In the cat, cells of the superior colliculus (SC) and the tectofugal pathways of the visual
system are highly selective for the direction of a moving visual stimulus. Deep layer units of …

Three types of looming-selective neurons have been found in the nucleus rotundus of
pigeons, each computing a different optical variable related to image expansion of objects …
