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.
Specification of the telencephalon occurs at E8.5 in mice, when expression of Foxg1 is initiated in this region.
