Topography of visual and somatosensory inputs to the pontine nuclei in zebra finches (Taeniopygia guttata) (2023)
Journal Article
Gaede, A., Gutiérrez-Ibáñez, C., Wu, P., Pilon, M., Altshuler, D., & Wylie, D. (2023). Topography of visual and somatosensory inputs to the pontine nuclei in zebra finches (Taeniopygia guttata). Journal of Comparative Neurology, https://doi.org/10.1002/cne.25556

Birds have a comprehensive network of sensorimotor projections extending from the forebrain and midbrain to the cerebellum via the pontine nuclei, but the organization of these circuits in the pons is not thoroughly described. Inputs to the pontine n... Read More about Topography of visual and somatosensory inputs to the pontine nuclei in zebra finches (Taeniopygia guttata).

Response properties of optic flow neurons in the accessory optic system of hummingbirds versus zebra finches and pigeons (2022)
Journal Article
Gaede, A., Baliga, V., Smyth, G., Gutierrez-lbanez, C., Altshuler, D., & Wylie, D. (2022). Response properties of optic flow neurons in the accessory optic system of hummingbirds versus zebra finches and pigeons. Journal of Neurophysiology, 127(1), 130-144. https://doi.org/10.1152/jn.00437.2021

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 example of this behavior. Optokinetic responses are mediated by directi...

Pretectal projections to the oculomotor cerebellum in hummingbirds ( Calypte anna ), zebra finches ( Taeniopygia guttata ), and pigeons ( Columba livia ) (2019)
Journal Article
Gaede, A. H., Gutierrez‐Ibanez, C., Armstrong, M. S., Altshuler, D. L., & Wylie, D. R. (2019). Pretectal projections to the oculomotor cerebellum in hummingbirds ( Calypte anna ), zebra finches ( Taeniopygia guttata ), and pigeons ( Columba livia ). Journal of Comparative Neurology, 527(16), 2644-2658. https://doi.org/10.1002/cne.24697

In birds, optic flow is processed by a retinal‐recipient nucleus in the pretectum, the nucleus lentiformis mesencephali (LM), which then projects to the cerebellum, a key site for sensorimotor integration. Previous studies have shown that the LM is h...

Neurons Responsive to Global Visual Motion Have Unique Tuning Properties in Hummingbirds (2017)
Journal Article
Gaede, A. H., Goller, B., Lam, J. P. M., Wylie, D. R., & Altshuler, D. L. (2017). Neurons Responsive to Global Visual Motion Have Unique Tuning Properties in Hummingbirds. Current Biology, 26(2), 279-285

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 mammals as the nucleus of the optic tract (NOT), is a key nucleus for glo...

Second tectofugal pathway in a songbird (Taeniopygia guttata) revisited: Tectal and lateral pontine projections to the posterior thalamus, thence to the intermediate nidopallium (2015)
Journal Article
Wild, J. M., & Gaede, A. H. (2015). Second tectofugal pathway in a songbird (Taeniopygia guttata) revisited: Tectal and lateral pontine projections to the posterior thalamus, thence to the intermediate nidopallium. Journal of Comparative Neurology, 524(5), 963-985

Birds are almost always said to have two visual pathways from the retina to the telencephalon: thalamofugal terminating in the Wulst, and tectofugal terminating in the entopallium. Often ignored is a second tectofugal pathway that terminates in the n...
