Discontinuation of affirmative action: Consequences for black educational equity, neurosurgical residency, and medical diversity, with consideration of potential adversity as a new path forward.

Background: The underrepresentation of the Black community in neurosurgery is concerning, especially given projections that racial minorities will become the majority in the U.S. by 2044. Yet, despite these forecasts, Black candidates make up less than 4% of those in neurosurgical training programs. The recent Supreme Court decision to end Affirmative Action underscores the urgency of addressing this disparity. This research delves into the implications of eliminating Affirmative Action on neurosurgery admissions and residencies. Methods: A comprehensive literature search was performed using PubMed, OVID Embase, and OVID Medline, employing the keywords "Black", "Neurosurgery", and "Residency". The Maslow Adversity Index (MAI) was created to integrate adversity as a factor in neurosurgery residency evaluation. Results: After Affirmative Action, Black college enrollment increased, peaking at 36% by 2020. However, Black medical students remain underrepresented in neurosurgery residencies. ALDC (Athletes, Legacies, Dean's List, Children of faculty/staff) admissions criteria favor White students. Furthermore, studies have highlighted the beneficial impacts of racial concordance on patient outcomes. The end of Affirmative Action necessitates new diversity strategies in admissions. A points-based assessment, inspired by Maslow's hierarchy, recognizes adversities faced by underrepresented applicants which could help residency programs enhance diversity, inclusivity, and equity in selection. Conclusion: Despite the growth in Black college attendance, disparities persist in specialized medical fields like neurosurgery. The end to Affirmative Action policies might exacerbate these disparities. Embracing holistic admission approaches, rooted in Maslow's hierarchy. This consideration is key for inclusive representation, impacting education, professions, and health outcomes.

Anatomical Parcellations of Brodmann's Areas 4 and 6: A Study on Cortical Thickness for Improved Neurosurgical Planning.

The cerebral cortex, comprising six layers known as the neocortex, is a sheet of neural tissue that contains regions for neurosurgical planning, including the primary motor cortex (PMC), the supplementary motor cortex (SMA), and the primary somatosensory cortex (PSC). However, knowledge gaps persist concerning the transition points between areas 3 to 4 and 4 to 6 and the SMA's extent. This study aims to develop a non-invasive protocol using T1/T2 weighted imaging to identify crucial anatomic borders around the primary and supplementary motor cortex for neurosurgical planning. A comprehensive literature search on the cytoarchitectonic borders of Brodmann's areas 3a, 4, and 6 was conducted, and relevant articles were selected based on their examination of these borders. The primary motor cortex was found to be the thickest region in the human brain, with discernible differences in thickness between areas 4 and 6. T2-weighted images revealed significant cortical thickness differences between the precentral and postcentral gyrus. Various methods have been employed to parcellate borders between cortical regions, including Laplace's equation and equi-volume models. A triple-layer appearance in the primary motor cortex and a novel method based on myelin content demonstrated consistent agreements with historically defined cytoarchitectonic borders. However, differentiating areas 4 and 6 from MR imaging remains challenging. Recent studies suggest potential methods for pre-surgically identifying the primary motor cortex and examining differences in cortical thickness in diseases. A protocol should be established to guide neurosurgeons in accurately identifying areas 4 and 6, possibly using imaging modalities superimposed on myelin maps for differentiation and determining area 6's anterior extent.
