Visual Masking: Understanding the Timing of Visual Perception
A groundbreaking study conducted by the Allen Institute revealed the existence of a peculiar phenomenon called ‘visual masking,’ wherein an individual fails to consciously perceive an image if another image is presented immediately afterward. This finding highlights the importance of the timing of visual stimuli in shaping our perception and raises questions about the role of neural circuits in this process.
Identification of Brain Region Involved in Visual Masking
By studying mice, the researchers identified a specific region of the brain that plays a critical role in visual masking. They trained mice to recognize and react to visual cues, then introduced a masking image shortly after the target image. As a result, the mice became unable to perform the task, indicating that they were no longer consciously aware of the initial image.
