Neuroepigenetics
Neuroepigenetics
Neuroepigenetics (pronounced: neuro-epi-genetics) is a subfield of epigenetics that specifically studies the epigenetic mechanisms in the nervous system.
Etymology
The term "Neuroepigenetics" is derived from three Greek words: "neuron" meaning nerve, "epi" meaning over or above, and "genetics" referring to the study of genes.
Definition
Neuroepigenetics is the study of how epigenetic changes in the genome can influence the function of the nervous system. This includes changes in DNA methylation, histone modification, and non-coding RNA molecules that do not change the underlying DNA sequence but can change the activity of genes and their expression in the brain.
Related Terms
- Epigenetics: The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.
- Nervous System: The complex network of nerves and cells that transmit signals between different parts of the body.
- Genome: The complete set of genes or genetic material present in a cell or organism.
- DNA Methylation: A biological process by which methyl groups are added to the DNA molecule.
- Histone Modification: A process by which the DNA wrapped around histones is chemically modified, affecting gene expression.
- Non-coding RNA: A form of RNA that does not encode for protein but has functions of its own.
