Bridging the Gap between Genes and Language Deficits in Schizophrenia: An Oscillopathic Approach

Elliot Murphy, Antonio Benítez-Burraco
2016 Frontiers in Human Neuroscience  
Additionally, we will show that candidate genes for schizophrenia are overrepresented among the set of genes that are believed to be important for the evolution of the human faculty of language.  ...  These genes crucially include (and are related to) genes involved in brain rhythmicity.  ...  Accordingly, nearly 5% of the human genes are expected to be related to the disease [assuming that the human genome contains about 20,000 protein-coding genes and that about 1000 of them have been associated  ...
