The hippocampus is essential for episodic memory, yet its coding mechanism remains debated. In humans, two main theories have been proposed: one suggests that concept neurons represent specific elements of an episode, while another posits a conjunctive code, where index neurons code the entire episode. Here, we integrate new findings of index neurons in humans […]

Recent insights from cognitive science have reshaped our understanding of the reliability of eyewitness memory. Many believe that eyewitness memory is unreliable, but a better way of thinking is that eyewitness memory, like other types of forensic evidence, can be contaminated. Because contaminated evidence yields unreliable results, the focus should be placed on testing uncontaminated […]

Over recent decades, temporal difference reinforcement learning (TDRL) models have successfully explained much dopamine (DA) activity. This success has invited heightened scrutiny of late, with many studies challenging the validity of TDRL models of DA function. Yet, when evaluating the validity of these models, the devil is truly in the details. TDRL is a broad […]
