Understanding how brain connections influence visual decision-making
Role of cortical connections to higher-order thalamic nuclei in visual decision-making
This study is looking at how certain connections in the brain help us make visual decisions, using monkeys to see how visual information moves through the brain, and it aims to understand how different brain cells affect what we see and how we decide based on that information.

What this research studies
This research investigates the role of specific brain connections in visual decision-making by studying non-human primates. It focuses on how visual information travels from the primary visual cortex to the prefrontal cortex through the pulvinar, a higher-order thalamic nucleus. The researchers will use a novel technique involving focused ultrasound to non-invasively open the blood-brain barrier, allowing them to manipulate brain circuits and observe their effects on visual perception and decision-making. By conducting psychophysical tasks, they aim to uncover the contributions of different brain cell types to these processes.
Who could benefit from this research
Good fit: Ideal candidates for participation or benefit from this research would be individuals with visual processing or attention-related disorders.
Not a fit: Patients with conditions unrelated to visual processing or those who do not have access to the research facility may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to improved understanding and treatment of visual processing disorders and attention-related conditions.
How similar studies have performed: While the specific approach of using focused ultrasound for this purpose is novel, similar studies have shown promise in understanding brain connectivity and decision-making.
