Allen Institute Visual Behavior 2P dataset overview¶

This dataset consists of neural activity measured with 2-photon calcium imaging in the visual cortex of mice performing an image change detection task.¶

In this task, mice learn to report changes in stimulus identity by licking a spout to earn a water reward.¶

In some sessions, the mice perform the task with familiar images they have seen many times during training. In other sessions, mice perform the task with novel images.¶

During 2-photon imaging sessions, 5% of stimulus presentations are randomly omitted, allowing us to examine the effect of unexpected events on neural activity.¶

The same population of cells is imaged over multiple days with varying sensory and behavioral conditions.¶
