Microdialysis News and Research

RSS

Microdialysis is a minimally invasive technique that is used for the continuous sampling of extracellular fluid. It is often used to measure the concentration of free analytes that are not bound to carrier proteins in a sample.

TIMP2 protein identified as key player in brain plasticity and memory

Researchers explored the molecular and cellular processes regulated by tissue inhibitor of metalloproteinases-2 (TIMP2) in the extracellular matrix (ECM) of the adult brain hippocampus.

Brain protein key to binge drinking? An interview with Dr. Candice Contet

Alcohol binge drinking is mostly driven by positive reinforcement, a process in which a rewarding experience (e.g., the euphoria one feels when intoxicated) strengthens the behaviour leading to this experience (e.g., going to a bar).

Six research teams awarded grant to accelerate discovery of new drugs for brain, nervous system disorders

CQDM, Brain Canada and the Ontario Brain Institute award close to $8.5M to six (6) multi-disciplinary and multi-provincial research teams across Canada to address unmet needs in neuroscience within their Focus on Brain strategic initiative. To this amount, $1.5M is added from the various research entities involved as in-kind contributions.

Brain protein plays key role in controlling binge drinking

Scientists at The Scripps Research Institute have discovered that a brain protein has a key role in controlling binge drinking in animal models. They found that deleting the gene for this protein in mice ramped up alcohol consumption and prevented the brain from signaling the rewarding properties of alcohol.
