Defining the Dendritic Field of the Connections That Link Cerebral Hemispheres


Researchers at the Max Planck Florida Institute for Neuroscience have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are arranged within a neuron’s dendritic field.


Study Links Moving More in Older Age to Sharper Memory


Older adults who move more, either with daily exercise or even simple routine physical activity like housework, may preserve more of their memory and thinking skills, even if they have brain lesions or biomarkers linked to dementia, according to a new study. Nevertheless, more research must be done to prove a causative link between the two.


Gut Bacteria Could Alter Parkinson's Treatment Efficacy


Patients with Parkinson’s disease are treated with levodopa, which is converted into dopamine, a neurotransmitter in the brain. In a new study, researchers show that gut bacteria can metabolize levodopa into dopamine. As dopamine cannot cross the blood-brain barrier, this makes the medication less effective – even in the presence of inhibitors that should prevent the conversion of levodopa.
