Rapidly and efficiently releases glutamate (Cat. No. 0218) when photolysed (350 - 365 nm excitation). Water soluble and stable at neutral pH, and pharmacologically inactive at neuronal glutamate receptors (up to 200 μM). 5.5 times more photosensitive than MNI-caged L-glutamate (Cat. No. 1490). Laser activation of MDNI-glu evokes a rapid increase in intracellular Ca2+ concentration in astrocytes.

Major depressive disorder is characterized by depressed mood and a loss of interest and/or pleasure. Updated in 2015 this poster highlights presynaptic and postsynaptic targets for the potential treatment of major depressive disorder, as well as outlining the pharmacology of currently approved antidepressant drugs.
Learning & Memory Poster
Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.
