Dynamics of dopamine transients in human olfactory epithelium during reward learning

This study measures fast dopamine transients in human olfactory epithelium during reward learning tasks and finds they shift from outcomes to cues, matching prediction error signals.

Cycle-by-cycle respiration waveforms are coupled with the shape of neural oscillations

The paper examines the coupling between respiration and neural oscillations by analyzing breath-by-breath waveform shapes in human brain recordings.

Targeting intracranial electrical stimulation to network regions defined within individuals causes network-level effects

This study shows that targeting intracranial electrical stimulation to network regions defined by precision functional mapping evokes network-level effects in individual epilepsy patients.

Concurrent presentation of memory-related odors and sounds nullified sleep reactivation benefits

The paper investigates how concurrent memory reactivation with odors and sounds during sleep affects memory consolidation, finding that some odors disrupt sound-induced memory benefits.

Social cognitive regions of human association cortex are selectively connected to the amygdala

The paper identifies specific connections between social cognitive association areas and the amygdala, suggesting a role for the medial nucleus in social cognition.

Oscillatory mechanisms of intrinsic brain networks

The paper investigates resting-state brain network organization using intracranial EEG, finding distinct connectivity patterns in key networks.

Smell-induced gamma oscillations in human olfactory cortex are required for accurate perception of odor identity

This study shows that gamma oscillations in human piriform cortex are critical for accurate odor identity perception during smell tasks.
