telencephalon

 [tel″en-sef´ah-lon]
1. one of the two divisions of the prosencephalon, consisting of the cerebrum.
2. the anterior of the two vesicles formed by specialization of the prosencephalon in embryonic development. Called also endbrain. adj., adj telencephal´ic.

tel·en·ceph·a·lon

(tel'en-sef'ă-lon), [TA]
The anterior division of the prosencephalon, which develops into the olfactory lobes, the cortex of the cerebral hemispheres, and the subcortical telencephalic nuclei, and the basal nuclei (ganglia), particularly the striatum and the amygdala.
Synonym(s): endbrain
[G. telos, end, + enkephalos, brain]

telencephalon

(tĕl′ĕn-sĕf′ə-lŏn′, -lən)
n.
The anterior portion of the forebrain, constituting the cerebral hemispheres and related parts. Also called endbrain.

tel′en·ce·phal′ic (-sə-făl′ĭk) adj.

telencephalon

The anterior part of the primitive forebrain or prosencephalon, which develops into the cerebral cortex, olfactory bulbs, and basal ganglia.

tel·en·ceph·a·lon

(tel'en-sef'ă-lon) [TA]

It was predicted that AIP expression would increase in the telencephalon, a structure homologous to the mammalian hippocampus, after exposure to a Y-maze apparatus, which served as a novel environment.
Inflammation was not a prominent feature in the brain.11 Only a few foci of mild perivascular cuffing were present in the white matter of the telencephalon. The inflammatory cells composing these cuffs were mostly T lymphocytes (stained with CD3, Novocastra, Newcastle Upon Tyne, England), together with some macrophages (CD68 stain).
Since knockout (KO) mice with a complete loss of mTOR showed a severe phenotype with specific defect in telencephalon formation and death during early/mid gestation [17, 78, 95, 96, 99, 101, 102], conditional knockout (CKO) mice were fundamental to elucidate the functional role of mTOR in the brain [77, 78, 87, 88].
