Mayo Clinic: Brain disorder suggests common mechanism may underlie many neurodegenerative diseases

... study published in August 2008, the consortium reported that eight patients who died from the disease had substantial loss of neurons in the midbrain area known as the substantia nigra. They also found a molecular signature of Perry syndrome "inclusions," or clumps, of a protein known as TDP-43 ...

Study first to pinpoint why analgesic drugs may be less potent in females than in males

... likely due to sex differences in mu-opioid receptor expression in a region of the brain called the periaqueductal gray area (PAG). Located in the midbrain area, the PAG plays a major role in the modulation of pain by housing a large population of mu-opioid receptor expressing neurons. Morphine and ...

Caltech scientists engineer supersensitive receptor, gain better understanding of dopamine system

The scientists then measured the electrical activities in A. tormotus' midbrain that is involved in sound processing and found marked electrical responses to sounds extending into the ultrasonic range -- both in the averaged ...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

... causing it to be active longer, Hohmann said. Apparently, several parts of the brain are involved in the effect, most notably a structure in the midbrain known as the periaqueductal gray. In this region, stress causes the release of the naturally occurring marijuana-like compounds in the brain. A ...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive
