Ceregene Presents Additional Clinical Data from Phase 2 Trial of CERE-120 for Parkinson's Disease
... as glial cell-derived neurotrophic factor (GDNF). The two molecules have similar pharmacological properties, and both have been shown to benefit the midbrain
dopamine neurons that degenerate in Parkinson's disease. Degeneration of these neurons is responsible for the major motor impairments of Parkinson's ...
University of Pennsylvania researchers find that the unexpected is a key to human learning
... They used microelectrode recordings obtained during deep brain stimulation surgery of Parkinson's patients to study neuronal activity in the SN, the midbrain
structure that plays an important role in movement, as well as reward and addiction. Patients with Parkinson's disease show impaired learning from ...

... systems. Once administered, the radiotracer revealed functional alterations in these systems by measuring the radioactive binding in the thalamus, midbrain
and pons (known to be acted upon by serotonin) and in the striatum (known to be acted upon by dopamine). The altered uptake activity in these regions ...
UC-Irvine scientists present groundbreaking research at Society for Neuroscience conference
... with hypertension. In this study, the researchers identified specific acupoints on hypertensive patients that trigger neurons in the hypothalamus, midbrain
and medulla to release chemicals that reduce excitatory responses in the cardiovascular system. This resulted in a decrease in heart activity and its ...

Neural Stem Cells Reduce Parkinsons Symptoms in Monkeys
... if this would be of any value in clinical settings.
Parkinsons disease is caused by a degeneration of dopamine neurons in an area of the midbrain
known as the substantia nigra, which is responsible for dopamine production. Reduced production of dopamine in late stage Parkinsons causes symptoms ...

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

"By uncovering the biological role of these receptors, especially with regard to their role in the midbrain
dopamine system, we show that they are excellent drug targets," says Drenan.
Obesity predisposition traced to the brain's reward system
