The God Brain: Roundtable Discussion on God and Spirituality for Brain Games

Is belief in God innate in our brains, as if it were installed by some divine programmer? Or is spirituality a more complex evolving adaptation that has both helped and harmed us as a species? National Geographic's Brain Games asks Neuroscience News.

Why the Brain Is Programmed to See Faces in Everyday Objects

Face pareidolia, the phenomenon of seeing facelike structures in inanimate objects, is a perceptual phenomenon that occurs when sensory input is processed by visual mechanisms that have evolved to extract social content from human faces.

Illusory Motion Reproduced by Deep Neural Networks Trained for Perception

Researchers have successfully reproduced illusory motion in deep neural networks that were trained for perception. The DNNs were able to accurately reproduce the direction of illusory rotation humans observe while looking at a popular optical illusion.

There’s a ‘Man in the Moon’: Why Our Brains See Human Faces Everywhere

Face pareidolia, a phenomenon where the brain is tricked into seeing human faces in inanimate objects, may occur as a result of the brain processing the perceived facial expression in the same sequential way it perceives a human face.

Brain Represents Optical Illusion as Delayed Reality

Researchers report the same subset of neurons encode actual and illusory flow motion, supporting the concept Jan Purkinje proposed 150 years ago, that "illusions contain visual truth".

Optical Illusions Explained in a Fly’s Eyes

It seems that flies are as susceptible to optical illusions as humans. Turning on and off some neurons that govern motion detection in flies, researchers were able to alter the insects' perception of illusory motion.
