The paper shows that task learning reshapes the geometric structure of neural representations in V1 to improve perceptual decision accuracy.

The paper shows that V1 neurons in mice form categorical representations of orientation during a discrimination task, which predict decision probabilities.

The paper shows that V1 neurons represent both visual stimuli and task context in overlapping but orthogonal population activity patterns during a cross-modal decision task.

The paper shows that anterior cingulate cortex encodes stimuli in low-dimensional subspaces during decision making, with context-gated suppression of irrelevant stimuli.

The paper shows that learning an orientation discrimination task in mice leads to a distortion of orientation representation in V1, improving cue representation and generalization.

The paper investigates how sounds modulate orientation and direction representation in mouse V1 L2/3 neurons, finding sound enhances responses of highly tuned neurons and suppresses untuned ones.

The paper shows that 3-5 Hz membrane potential oscillations reduce gain in excitatory neurons but not interneurons in awake mice during visual tasks.
