Horizontal and vertical components of head movement are controlled by distinct neural circuits in the barn owl
Tom Masino,Eric I. Knudsen +1 more
TL;DR: The data show that subsequent to the retinotopic code for space in the optic tectum yet before the motor neuron code for muscle tensions there exists a code for head movement in which upward, downward, leftward and rightward components of movement are controlled by four functionally distinct neural circuits.

Brainstem control of orienting movements: intrinsic coordinate systems and underlying circuitry.
TL;DR: Studies reviewed herein indicate that following the retinotopic coding of spatial location in the retina and tectum, spatial location information appears to enter a different coordinate system at tegmental levels in which spatial aspects of orienting movement are coded in terms of their discrete horizontal and vertical components.
Orienting Head Movements Resulting from Electrical Microstimulation of the Brainstem Tegmentum in the Barn Owl
Tom Masino,Eric I. Knudsen +1 more
TL;DR: The data demonstrate directly that at the level of the midbrain tegmentum there exists a three-dimensional Cartesian representation of head-orienting movements such that horizontal, vertical, and roll components of movement are encoded by anatomically distinct neural circuits.
Anatomical pathways from the optic tectum to the spinal cord subserving orienting movements in the barn owl
Tom Masino,Eric I. Knudsen +1 more
TL;DR: It is hypothesize that the medial efferent pathway and its brainstem target nuclei are primarily responsible for tectally mediated orienting head movements in the barn owl.
Parallel pathways mediating both sound localization and gaze control in the forebrain and midbrain of the barn owl
TL;DR: The hypothesis that sound localization and gaze control are mediated in parallel in the midbrain and forebrain was tested in the barn owl and it was found that all of the owls were capable of localizing and orienting to contralateral auditory stimuli on some trials with the optic tectum inactivated or lesioned.
