This study shows that ketamine alters time perception and neural activity in the parietal area LIP in macaques, affecting both single-neuron and population-level dynamics.

The paper shows that decoupling perceptual choices from motor responses reduces choice-history effects in non-human primates.

The paper shows that humans delay perceptual decisions until relevant choices are presented, using a bounded diffusion model to explain decision-making based on stored sensory information.

This paper introduces a minimal mean-field neural circuit model that explains flexible perceptual decisions by integrating sensory evidence and action selection, replicating parietal cortical activity and decision dynamics.

This study shows that inactivating the lateral intraparietal area in monkeys leads to decision-making deficits that are compensated for quickly within sessions and more slowly across sessions.

This study shows that monkeys delay decision formation until motor actions are available, with neurons retrieving evidence from short-term memory during abstract decisions.

The paper compares sensory and motor preparatory responses in LIP neurons during decision-making tasks, finding that motor responses track evidence accumulation while sensory responses do not.
