Telencephalon

The telencephalon is the most anterior region of the future brain. Together with the diencephalon, it develops from the prosencephalon. The telencephalon can be first detected on E9.5 in mouse and gives rise to the cerebral cortex, the striatum, the olfactory bulb and the limbic system. The telencephalon is populated by a large diversity of neurons, including glutamatergic projection neurons, GABA (γ-aminobutyric acid)-ergic interneurons and projection neurons, as well as cholinergic interneurons and projection neurons.
