Understanding how visual signals are processed in the brain
Studies of direct and transthalamic pathways in visual cortex
['FUNDING_R01'] · UNIVERSITY OF CALIFORNIA AT DAVIS · NIH-10898518
This study is looking at how a part of the brain called the pulvinar helps send visual information to different areas, using mice and monkeys to see how two different pathways work, and it aims to learn more about how we all process what we see.

What this research studies
This research investigates the pulvinar, a complex brain structure involved in visual processing, to understand how it communicates visual signals between different areas of the brain. By using mouse and monkey models, the study examines two pathways—the direct and transthalamic pathways—through which visual information is transmitted. Researchers will employ optogenetic techniques to selectively inhibit these pathways and observe the effects on visual tasks and neuron responses. The goal is to uncover the distinct functions of these pathways and how they may differ across species, providing insights into visual processing in mammals.
Who could benefit from this research
Good fit: Ideal candidates for participation or benefit from this research would include individuals with visual processing disorders or those interested in the underlying mechanisms of vision.
Not a fit: Patients with conditions unrelated to visual processing or those who do not have access to the research location may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could enhance our understanding of visual processing, potentially leading to improved treatments for visual disorders.
How similar studies have performed: While the specific approach of comparing direct and transthalamic pathways in visual processing is novel, similar studies have shown success in understanding brain communication pathways.
