Name:	telencephalon
Synonyms:
Definition:	The anterior and dorsal forebrain neuromere. In ray-finned fishes and most pronounced in teleosts the roof plate of the embryonic telencephalon extends laterally with the effect that the paired alar plates forming the hemispheric walls roll out lateroventrally in a process called eversion. This is unlike the development in other vertebrate groups. From Neuroanatomy of the Zebrafish Brain.

Name:	heterochromatin formation
Synonyms:	chromatin silencing, chromatin-mediated silencing, establishment of chromatin silencing, establishment of heterochromatic silencing, establishment of heterochromatin architecture, establishment of heterochromatin architecture involved in chromatin silencing at centromere outer repeat region, establishment of heterochromatin architecture involved in chromatin silencing at pericentric region, heterochromatic silencing, heterochromatin assembly, heterochromatin assembly involved in chromatin silencing, heterochromatin assembly involved in chromatin silencing at centromere outer repeat region, heterochromatin assembly involved in chromatin silencing at pericentric region, heterochromatin formation involved in chromatin silencing, heterochromatin formation involved in chromatin silencing at centromere outer repeat region, heterochromatin formation involved in chromatin silencing at pericentric region, heterochromatin maintenance, TGS, transcriptional gene silencing
Definition:	An epigenetic gene silencing mechanism in which chromatin is compacted into heterochromatin, resulting in a chromatin conformation refractory to transcription. This process starts with heterochromatin nucleation, its spreading, and ends with heterochromatin boundary formation.
