Selective Nerve Block of A- or C-Afferents Confirms Dual Role in Touch Pleasantness but Not Touch-Pain Modulation

This study uses nerve blocks to show that both A- and C-fibers contribute to touch pleasantness, but only C-fibers modulate pain.

Pain-related opioidergic and dopaminergic neurotransmission: Dual Meta-Analyses of PET Radioligand Studies

This paper conducts two meta-analyses of PET radioligand studies to identify regions of shared and unique opioid and dopamine neurotransmission during pain-related processes.

The onset and offset of noxious stimuli robustly modulate perceived pain intensity

This study shows that changes in noxious stimulus intensity, whether increasing or decreasing, significantly affect perceived pain intensity, with onset hyperalgesia and offset analgesia occurring bidirectionally.

BOLD Decoding of Individual Pain Anticipation Biases During Uncertainty

The paper uses machine learning to decode individual pain anticipation biases during uncertainty from fMRI data, identifying stable neural patterns associated with different anticipation responses.

Noninvasive Vagus Nerve Stimulation Alters Neural Response and Physiological Autonomic Tone to Noxious Thermal Challenge

This study shows noninvasive vagal nerve stimulation reduces neural and physiological responses to noxious thermal stimuli by modulating pain and autonomic circuits.
