Brain perception: How the visual cortex manages ambiguity

Scientists are exploring how the human brain interprets ambiguous visual stimuli, a phenomenon known as pareidolia, where people perceive familiar shapes, such as faces or animals, in random patterns like clouds. While once associated with mental health disorders, pareidolia is now understood as a common cognitive process.

A research team led by Dr. Mehdi Borjkhani, involving the ICTER Eye Research Center at the Institute of Physical Chemistry of the Polish Academy of Sciences, along with institutions in Iran and Germany, has studied how the visual cortex maintains stable recognition despite varying conditions. Their research, published in the 'Journal of Computational Neuroscience', examines how the brain achieves consistent interpretations—such as recognizing a familiar face in different lighting or angles—without allowing minor sensory differences to cause chaotic or divergent responses.
