Description
The investigators conducted experiments with seven macaque monkeys to understand how measures of neural activity in the lateral intraparietal (LIP) cortex corresponded with decision-making as they performed different tasks: a motion discrimination task and two variations on a novel face categorization task where subjects reported the faces' species or expression. They found that neuron firing rates in the LIP cortex varied depending on the task, which suggested that decision-making and action planning were processes that underwent context-dependent interpretation of information. These observations challenge existing models of decision-making in the brain which assume that decision variables are encoded and read out in a consistent manner regardless of the task context.
