When mGluRs were suppressed with 1 mM (S)-MCPG, NMDAR effect was not enough powerful to generate action potentials in response to repetitive electrical stimulation of neural tissue. Figure: evoked post-synaptic potentials with action potentials (under control) and without action potentials (after application of MCPG.
Literature in this Area
Tocris offers the following scientific literature in this area to showcase our products. We invite you to request* or download your copy today!
*Please note that Tocris will only send literature to established scientific business / institute addresses.
Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
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.
