Apple, Butterfly, Cat -- as you read these words, did a picture come to mind? The clarity of the picture that appeared in your head depends on how excitable your neurons are, according to a research.
The strength of a person’s mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person’s ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.
