Morphed Images of Hollywood Celebrities Reveal How Neurons React

An international team of scientists has shown how individual neurons in the human brain react to ambiguous morphed faces.

The team involves Professor Rodrigo Quian Quiroga, director of the Centre for Systems Neuroscience and Head of Bioengineering at the University of Leicester.

For this, the researchers used images of celebrities, such as Angelina Jolie and Halle Berry, morphed together to create an ambiguous face which test subjects were asked to identify.

The study found that for the same ambiguous images, the neurons fired according to the subjective perception by the subjects rather than the visual stimulus. For example, a neuron originally firing to Whoopi Goldberg fired to a morph image between Goldberg and Bob Marley only when the subject identified the morphed image as Goldberg and remained silent when the subject said the very same image was Marley.
