The paper uses fMRI and representational similarity analysis to map cortical representations of paraspinal sensory input, finding a dermatomal organization in sensorimotor cortices.

This paper improves 1H-MRS quality in the brainstem periaqueductal grey using spectral registration, showing increased SNR and reduced linewidth and CRLBs.

This study investigates the neurochemical basis of pain relief modulation, finding that dopaminergic signaling, not opioidergic, enhances relief perception through active decision-making and unpredictability.

This study investigates the role of the prefrontal cortex in placebo analgesia by comparing brain activity during high and low heat conditions with inert creams, finding reduced prefrontal activation despite lower pain ratings.

This study investigates placebo analgesia in fibromyalgia patients and healthy individuals, finding no differences in neural or behavioral responses despite opioid receptor antagonism.

The paper uses machine learning to analyze neural patterns in chronic low back pain patients to investigate differences between pain-related fear constructs.
