Hagai Bergman

Hagai Bergman (Hebrew: הגאי ברגמן; born 1952 in Tel Aviv) is an Israeli neuroscientist best known for his work on the basal ganglia and their involvement in movement disorders, especially Parkinson's disease.

[5] Bergman's research has focused on several key areas: His work has led to a deeper understanding of the neural circuits involved in motor control and has had a direct impact on the treatment strategies for Parkinson's disease.

[6] However, in their experiment, Bergman and colleagues could show that lesioning the subthalamic nucleus led to sudden reversal of multiple cardinal symptoms of Parkinson's Disease, such as tremor.

Their study ultimately led to the application of deep brain stimulation to the structure by the team of Alim Louis Benabid and Pierre Pollak in Grenoble.

Since then, deep brain stimulation has been applied in over 200,000 patients[7] and has led to significant improvements in motor function and quality of life[8] in people living with Parkinson's Disease.
