Abstract
The vascularisation of the brain amygdala is reviewed from the few studies that have been devoted to it. This vascularisation apparently poor is actually rich enough but made of extremely fine vessels that only Indian ink injections can reveal.
The authors remind that fMRI is based on the variations of the blood flow travelling these vessels and give some examples of this very interesting method of in vivo central nervous system’s exploration.

Notes
- 1.
The anterior choroidal artery is born from segment C4 (supra-clinoid segment or cerebral segment) of the internal carotid artery. This artery can also develop from the middle cerebral artery or the posterior communicating artery. Through the choroid plexus of the lateral ventricle (whose lower end it supplies), it establishes a remarkable anastomotic system between the carotid system, which it belongs to, and the vertebro-basilar system to which belong the posterior choroidal arteries, branches of the posterior cerebral arteries.

J Hellsten et al., in 2005, had already observed that therapeutic treatments, which are effective in treating depressive syndromes, can increased the vascularity of the hippocampus by an extra 30°/°!
