Researchers decode the neuronal basis of decision-making processes and can thus predict actions.
In a new study, neuroscientists show how decision-making processes are controlled in the primate brain during foraging. The team, including a researcher from the German Primate Center -- Leibniz Institute for Primate Research in Göttingen, trained two rhesus monkeys to search for food in an experimental room.
For the study, a team of researchers from Germany and the USA trained two rhesus monkeys to explore an experimental room with two button-controlled food boxes. Each time the monkeys pressed a button on one of the boxes, they had the chance to receive food pellets. The two boxes were set in such a way that the time intervals between the individual food dispenses became longer and longer during an experimental run.
"However, characterizing the activity patterns of individual neurons does not always reveal the whole story when we study complex decision-making processes," Shahidi explains."Complex behaviors consist of different components that are sometimes processed simultaneously in the same brain area.
