Visual Decision Making Section

About our work

The Visual Decision Making Section seeks to help uncover the mechanisms and circuitry of visually driven decision-making. Our work is guided by three broad questions:

  • How are such decisions influenced by internal state and behavioral context?
  • How do internal states and neuromodulatory circuits influence the encoding of the incoming visual signals in the visual cortex?
  • How are these combined signals used to guide behavior in healthy mammalian brains?

Answering these questions is aimed at improving our understanding of how these mechanisms fail in psychiatric and neurological diseases. To address these questions we combine computational, behavioral, pharmacological, functional imaging, videography and large-scale electrophysiological approaches in mammals, and, through collaboration, machine-learning techniques.

Separating movement from sight when studying the brain’s visual cortex

November 2, 2023

In primates, activity in the visual cortex—a part of the brain that processes signals from the eyes—is largely unaffected by the body’s own movements, according to a new study from scientists at the National Eye Institute (NEI).
Two hat-shaped objects, one pointing towards the viewer (concave) and one away from the viewer (convex)

Scientists uncover how decisions about what we see are relayed back through the brain

July 27, 2021

Researchers at the National Institutes of Health have discovered that decisions based on visual information is broadcast widely to neurons in the visual system, including to those that are not being used to make the decision.
