A study comprising of 26 patients with Parkinson’s disease (PD) utilized a robotic method to initiate “presence hallucinations” and found that altered sensorimotor processing in the frontotemporal network could be the cause behind hallucinations that are experienced by the PD patients. These findings led to the identification of the neural network that is responsible for the occurrence of hallucinations including the inferior frontal gyrus, the ventral premotor cortex and the posterior middle temporal gyrus. The presence hallucination network was selectively disrupted in PD patients and could be predictive of the occurrence of symptomatic presence of hallucinations and associated cognitive decline. This brain network could further be explored as a biomarker in more severe forms of hallucinations and cognitive deficit diseases. Further, the use of robotic technology during MRIs can help capture the neural activity associated with hallucinations.
