Reactivation of reward representations associated with the reinforcement of behavior

The paper investigates how reward-related neural representations are reactivated during learning to reinforce behavior, finding that reactivation occurs when reward contingencies are consistent across tasks.

Low frequency traveling waves in the human cortex coordinate neural activity across spatial scales

The paper examines low frequency traveling waves in the human cortex and finds they coordinate neural activity across spatial scales and with single unit spiking.

Signal complexity of human intracranial EEG tracks successful associative memory formation across individuals

The paper identifies neural signal complexity metrics in intracranial EEG that correlate with successful associative memory formation across individuals.

The experience of vivid autobiographical reminiscence is supported by personal semantic representations in the precuneus

The paper identifies a brain network, including the precuneus, that represents personal semantic content during vivid autobiographical recollection using lifelogging and fMRI data.
