| + | The diagnosis of aphantasia has sparked considerable debate within the scientific and medical communities. While some researchers argue that aphantasia is a genuine neurological condition, others question its validity, proposing that it may be more of a subjective experience or an extreme end of a spectrum of visual imagery abilities. | ||

| Research exploring this phenomenon investigates how differences in visualization abilities affect involuntary imagery and its neural underpinnings. For example, participants were asked either to visualize or to suppress visualization of specific scenarios, like a pink elephant, while their brain activity was monitored using electroencephalography (EEG). The vividness of individuals’ voluntary visualizations correlated with their likelihood of experiencing involuntary imagery, influenced by neural mechanisms tied to disinhibition, | Research exploring this phenomenon investigates how differences in visualization abilities affect involuntary imagery and its neural underpinnings.
