Can gut infection trigger Parkinson's disease?

A new study by Montreal scientists published today in Nature demonstrates that a gut infection can lead to a pathology resembling Parkinson's disease (PD) in a mouse model lacking a gene linked to the human disease.

Unexplored neural circuit modulates memory strength

Learning to avoid negative experiences requires an interplay of two distinct brain circuits, one to interpret "Yikes!" and drive learning, and the other, unexpectedly, to dial in the strength of that memory, a new fruit fly ...

Intervening in glial cells protects neurons in Parkinson's model

Loss of dopaminergic neurons is a hallmark of Parkinson's disease pathology. When dopaminergic neurons are stressed, they send out a call for help to nearby glial cells that are tasked with providing neuronal support, protection ...

Monkey gaze study shows dopamine's role in response inhibition

University of Tsukuba researchers report the importance of the brain's dopaminergic system for inhibiting already-planned actions. They trained monkeys to redirect their gaze toward targets presented on a screen, apart from ...

Drug homing method helps rethink Parkinson's

The brain is the body's most complex organ, and consequently the least understood. In fact, researchers like Michael Tadross, MD, PhD, wonder if the current research methods employed by neuroscientists are telling us as much ...

Fly protein has protective effect on dopaminergic neurons

Parkinson's disease is a neurodegenerative disorder that affects dopamine-producing or dopaminergic neurons. The progressive loss of these neurons is what leads to impairment in movement coordination in those suffering from ...
