Epigenetic codes in cognition and behaviour


Gräff, J; Mansuy, I M (2008). Epigenetic codes in cognition and behaviour. Behavioural Brain Research, 192(1):70-87.

Abstract

The epigenetic marking of chromatin provides a ubiquitous means for cells to shape and maintain their identity, and to react to environmental stimuli via specific remodeling. Such an epigenetic code of the core components of chromatin, DNA and histone proteins, can thus be stable but is also highly dynamic. In the nervous system, epigenetic codes are critical for basic cellular processes such as synaptic plasticity, and for complex behaviours such as learning and memory. At the same time, epigenetic marks can be stably transmitted through mitosis and meiosis, and thereby underlie non-genomic transgenerational inheritance of behavioural traits. In this review, we describe recent findings on the role and mechanisms of epigenetic codes in the brain, and discuss their implication in synaptic plasticity, cognitive functions and psychiatric disorders. We provide examples of transgenerational inheritance of epigenetic marks that affect simple morphological traits or complex processes such as disease susceptibility, and point to the potential implication of epigenetic codes in medicine and evolution

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
