In neuroanatomy and neuroembryology, a ganglionic eminence (GE) is a transitory brain structure present in the embryonic and fetal stages of brain development. The eminences are found in the ventral part of the telencephalon, where they form bulges in the ventricles. These bulges develop into the basal ganglia.[1] They also contribute significantly in building up the GABAergic cortical cell population.
Ganglionic eminences are categorized into three groups based on location:
In humans, ganglionic eminences serve as the source of GABAergic thalamic neurons, which migrate through another transient brain structure peculiar to humans, the gangliothalamic body (GTB). GEs also present an intermediate target for the axons growing from the thalamus into the cortex and vice versa. They disappear just before birth.
