=====Inferior choroidal point=====

Entry point of the [[anterior choroidal artery]] (AChoA) at the anterior origin of the [[choroid plexus]] into the [[temporal horn]].

The [[choroidal fissure]] is located between the [[thalamus]] and [[fimbria]]; it begins at the inferior choroidal point behind the head of the [[hippocampus]] and constitutes the medial wall of the posterior two-thirds of the temporal horn
((Wen HT, Rhoton AL Jr, de Oliveira E, Cardoso AC, Tedeschi H, Baccanelli M,
Marino R Jr. Microsurgical anatomy of the temporal lobe: part 1: mesial temporal 
lobe anatomy and its vascular relationships as applied to
amygdalohippocampectomy. Neurosurgery. 1999 Sep;45(3):549-91; discussion 591-2.

The cortical projection of the [[inferior choroidal point]] (ICP) is a reliable landmark for reaching the temporal horn
((Frigeri T, Rhoton A, Paglioli E, Azambuja N. Cortical projection of the
inferior choroidal point as a reliable landmark to place the corticectomy and
reach the temporal horn through a middle temporal gyrus approach. Arq
Neuropsiquiatr. 2014 Oct;72(10):777-81. PubMed PMID: 25337730.)).

Two easily identifiable points, including the middle cerebral artery bifurcation and the inferior choroidal point, may define a line that reliably disconnects the amygdala complex from the remaining temporal and frontal lobes. These landmarks may assist in resection of the amygdale while preserving important adjacent structures, including the striatum
