Hippocampus-dependent cognitive enhancement induced by systemic gintonin administration

A number of neurological and neurodegenerative diseases shares impaired cognition as one of common symptoms. Therefore, the development of clinically applicable therapies to enhance cognition has yielded significant interest. Previously, we have shown that activation of lysophosphatidic acid receptors (LPARs) via gintonin application potentiates synaptic transmission by the blockade of K+ channels in the mature hippocampus. However, whether gintonin may exert any beneficial impact directly on cognition at the neural circuitry level and the behavioral level has not been investigated.
