Neuroimaging techniques

Definition

Neuroimaging techniques are advanced methods used to visualize and analyze the structure and function of the brain. These techniques provide valuable insights into how various neurological conditions, such as autism and savant syndrome, can influence artistic abilities and perceptions. By utilizing these imaging methods, researchers can explore brain activity and connectivity patterns that are unique to individuals with these conditions, shedding light on their extraordinary artistic talents and cognitive processes.
