Topic: visual imagery

Mental imagery refers to our remarkable capacity to generate percepts, emotions, and thoughts in the absence of external stimuli. This ability allows us to generate art, simulate actions and outcomes, remember previous experiences, and imagine new ones. Little is known about the mechanisms that enable mental imagery. While neuroimaging data shows that sensory areas are active during imagery (1–4), it remains unknown whether this is due to reactivation of the same neurons that support perception or separate circuitry located in the same regions. Here we examine the single-neuron mechanisms of v

Aphantasia is a condition that involves an inability to generate voluntary visual images and it occurs in about 3-4% of the population. Previous research has shown that people with aphantasia have deficits in motor simulation. The aim of this study was to investigate the neural activity during kinesthetic motor imagery (KMI) and internal visual-motor imagery (IVMI). Gender, education, handedness and age were matched for the 15 subjects (8 aphantasics; 4 men) aged 19-46 years (M = 26,29; SD = 9,90) who participated in the study. All subjects completed the second Polish version of the Vividness
