The anterior segment of the brain, including the cerebrum and olfactory lobes; the forebrain.
The most rostral of the primary vesicles that are present in the early neural tube, which later gives rise to two secondary vesicles: telencephalon (prospective cerebral hemispheres) and diencephalon (prospective thalamus, hypothalamus).
the anterior portion of the brain; the part of the brain that develops from the anterior part of the neural tube
Latin pro = in front, and Greek enkephalos = brain; hence, the part of the brain rostral to the midbrain.
That part of the nervous system developed from the first cerebral vesicle, the hemispheres with the corpora striata and the optic thalamus and the adjacent structures.
proso (forward), enkephalos (brain).
The most rostral of the three primary vesicles of the mbryonic brain. The adult derivatives of the forebrain are the cerebral hemispheres, striatum, diencephalon, lateral and third ventricles.
Gr. pros - forward, in advance of; Gr. kephale -a head]. The most anterior brain region of developing embryos which later divides into the telencephalon (most anterior brain region) and diencephalon. These regions later differentiate into the cerebral hemispheres, thalamus and hypothalamus and optic vesicles. Synonym: forebrain.
In the anatomy of the brain of vertebrates, the prosencephalon (or forebrain) is the rostral-most portion of the brain. The prosencephalon, the mesencephalon (midbrain), and rhombencephalon (hindbrain) are the three primary portions of the brain during early development of the central nervous system.
