A new study by Yale scientists has identified a specific brain region that may cause paranoia by comparing behavioral data from monkeys and humans. This research utilized a novel approach, aligning animal and human studies using a computational model to analyze how participants perceive environmental stability and adapt to changes. The study, which also examined the effects of specific brain lesions in monkeys, provides insights into the neural underpinnings of paranoia and suggests a framework for future research on human cognition using simpler species.
This could ultimately aid in developing better pharmaceutical treatments for paranoia. Credit: SciTechDaily.com The capacity to adjust beliefs about one’s actions and their consequences in a constantly changing environment is a defining characteristic of advanced cognition.
Disruptions to this ability, however, can negatively affect cognition and behavior, leading to such states of mind as paranoia, or the belief that others intend to harm us. In a new study, Yale scientists uncover how one specific region of the brain might causally provoke these feelings of paranoia. Their novel approach — which involved aligning data collected from monkeys with human data — also offers a new cross- species framework through which scientists might better understand human cognition through the study of other species.
Their findings, and the approach they used, were recently published in the journal Cell Reports . While past studies ha.
