Microsurgical Anatomy and Approaches to the Cerebral Central Core.

Objective: Through a cadaveric study, we divided the cerebral central core (CCC) into different areas and have proposed a corresponding neurosurgical approach for each sector. As a secondary objective, we analyzed the cortical and subcortical microsurgical anatomy of the CCC. The CCC includes the insula, extreme capsule, claustrum, external capsule, lenticular nucleus, internal capsule, caudate nucleus, and thalamus.

Fractal anatomy of the hippocampal formation.

Purpose: We believed that the hippocampal complex is a fractal, and we try to demonstrate it.

Methods: We selected 12 magnetic resonance (MR) studies from healthy brains. Five women and 7 men without neurological or psychiatric disease were analyzed.

[Microsurgical anatomy importance of A1-anterior communicating artery complex].

Background: The anterior cerebral artery originates from the bifurcation of the internal carotid artery lateral to the optic chiasm, then joins with its contralateral counterpart via the anterior communicating artery. A1-anterior communicating artery complex is the most frequent anatomical variants and is the major site of aneurysms between 30 to 37%.

Objective: Know the anatomy microsurgical, variants anatomical and importance of complex precommunicating segment-artery anterior communicating in surgery neurological of the pathology vascular, mainly aneurysms, in Mexican population.

Microsurgical anatomy of the extracerebral segment of recurrent artery of Heubner in the Mexican population.

Background: The recurrent artery of Heubner (RAH) is originated commonly from the anterior cerebral artery. Its extracerebral segment is directed toward the anterior perforate substance where it penetrates the cortex.

Methods: The RAH was dissected from 15 human brains from Mexican population, and the presence, length, branches, course and either RHAs or anterior communicating artery complex variants were reported.
