Target selection for saccadic eye movements: direction-selective visual responses in the superior colliculus.
We investigated the role of the superior colliculus (SC) in saccade target selection in rhesus monkeys who were trained to perform a direction-discrimination task. In this task, the monkey discriminated between opposed directions of visual motion and indicated its judgment by making a saccadic eye movement to one of two visual targets that were spatially aligned with the two possible directions...
متن کاملDirection-selective visual responses in macaque superior colliculus induced by behavioral training.
In a previous report, we described a heretofore undetected population of neurons in the intermediate and deep layers of the monkey superior colliculus (SC) that yielded directionally selective visual responses to stimuli presented within the central 4 degrees of the visual field. We observed these neurons in three monkeys that had been extensively trained to perform a visual direction discrimin...
متن کاملSpatial relationships of visuomotor transformations in the superior colliculus map.
The oculomotor system is well understood compared with other motor systems; however, we do not yet know the spatial details of sensory to motor transformations. This study addresses this issue by quantifying the spatial relationships between visual and motor responses in the superior colliculus (SC), a midbrain structure involved in the transformation of visual information into saccadic motor c...

encountering each other on the migration south. But the new research reports results from six sea-floor acoustic recorders placed in the western George’s Bank off Cape Cod deployed in two triangular arrays each of three devices. The recorders were placed around 3 kilometres apart in the triangular array and the centre of two sets were 18.4 kms apart. Based upon the detection of song from one wh...
متن کاملThe visuotopic component of the multisensory map in the deep laminae of the cat superior colliculus.
A well-defined map of visual space is located in the deep laminae of the cat superior colliculus. The horizontal meridian is oriented rostral-caudal, while the vertical meridian is oriented perpendicular to it in the rostral third of the structure. This map represents the entire contralateral visual field and extends approximately 40 degrees into ipsilateral visual space. Although the deep-lami...
