Equiluminant Border Ownership Cells as a Missing Link in Color Form Perception

The paper proposes and models a sub-population of border ownership neurons that respond to equiluminant borders, suggesting they are missing links in color form perception.

Real-world visual search goes beyond eye movements: Active searchers select 3D scene viewpoints too

The paper studies active visual search in 3D environments, finding that participants select viewpoints and use head/eye movements to search for objects, improving efficiency over time.

Attention to a point in time causes a suppressive wake for subsequent time points

The paper investigates whether temporal attention suppresses processing of nearby time points, finding that attention to an expected time frame improves accuracy while a suppressive wake reduces accuracy after the expected frame.

Feature-based attention induces non-linearities in neuronal tuning and behavior during visual motion perception

The paper investigates how feature-based attention creates non-linearities in neuronal tuning and behavior during visual motion perception by showing attentional suppressive surrounds in neurons and similar effects in human motion discrimination.

Multiplicative modulations in hue-selective cells enhance unique hue representation

The paper proposes a hierarchical model of hue representation in the visual cortex, showing that multiplicative modulations contribute to encoding unique hues and that model V4 neurons can encode unique hues.
