Obesity Is Associated with Decreased μ-Opioid But Unaltered Dopamine D2 Receptor Availability in the Brain
Henry K. Karlsson,Lauri Tuominen,Jetro J. Tuulari,Jussi Hirvonen,Riitta Parkkola,Semi Helin,Paulina Salminen,Pirjo Nuutila,Lauri Nummenmaa +8 more
TL;DR: Obesity appears to have unique neurobiological underpinnings in the reward circuit, whereby it is more similar to opioid addiction than to other addictive disorders, and Behavioral and pharmacological strategies for recovering opioidergic function might thus be critical to curb the obesity epidemic.

Bariatric Surgery Induces White and Grey Matter Density Recovery in the Morbidly Obese: A Voxel-Based Morphometric Study
Jetro J. Tuulari,Henry K. Karlsson,Olli Antikainen,Jussi Hirvonen,Jussi Hirvonen,Tam Pham,Paulina Salminen,Mika Helmiö,Riitta Parkkola,Pirjo Nuutila,Pirjo Nuutila,Lauri Nummenmaa,Lauri Nummenmaa +12 more
TL;DR: In this paper, the effects of surgery-induced weight loss in the morbidly obese brain were investigated using voxel-based morphometry (VBM) to quantify grey and white matter densities.

TL;DR: In this article, the authors examined the functional neural basis of music-induced emotions in a large sample (n = 102) of subjects who listened to emotionally engaging (happy, sad, fearful, and tender) pieces of instrumental music while their haemodynamic brain activity was measured with functional magnetic resonance imaging.
