Area of Science:

Neuroscience
Cognitive Science
Visual Processing

Background:

Internal brain states significantly influence sensory processing during behavior.
Spatial attention in primates enhances behavioral and neural responses to attended stimuli.

Purpose of the Study:

To develop a visual spatial task for mice to study spatial attention.
To measure network, cellular, and subthreshold activity in the primary visual cortex during this task.

Main Methods:

Developed a novel visual spatial task for mice.
Measured local field potential (LFP) responses.
Performed whole-cell patch-clamp recordings in the primary visual cortex.

Main Results:

Behavioral improvements correlated with strengthened LFP responses to stimuli within the receptive field (RF).
Enhanced neuronal responses and suppressed noise correlations were observed.
Increased synaptic activity depolarized membrane potentials at behaviorally relevant locations.

Conclusions:

Mice display fundamental signatures of visual spatial attention across multiple levels.
This study offers new insights into cognitive enhancement of sensory signals in the visual cortex.
