Cellular and Molecular Neuroscience

Cognitive and Behavioural Neuroscience


The Genes to Cognition programme (G2C) established a framework for studying genes, brain and behaviour in order to link basic molecular research from genomes and experimental genetic organisms with human clinical studies of cognition. The G2C framework was developed around the current understanding of the molecular basis of learning & memory.

The G2C programme collects and integrates data in the areas of psychiatry, human and mouse psychology, cellular neurophysiology and cell biology, proteomics and biochemistry, molecular biology, human and mouse genetics and genomics.
