Cortical Anatomy: Medial Hemisphere

Cortical Anatomy: Brodmann Areas

In this episode of The Neurosurgery Review, I, Mustafa Farooq, a fourth-year medical student at the Medical College of Georgia and neurosurgery residency applicant, delve into the fascinating world of Brodmann areas—the functional mapping of the cerebral cortex. We explore the key Brodmann areas, including Area 4 (primary motor cortex), Area 17 (primary visual cortex), Area 22 (Wernicke's area), and others, highlighting their anatomical locations, functional roles, and relevance in neurosurgical practice. This detailed overview aims to provide a high-yield understanding of these regions, their clinical implications, and their importance in diagnosing and treating neurological disorders.

Cortical Anatomy: Medial Hemisphere

In this episode of The Neurosurgery Review, I, Mustafa Farooq, a fourth-year medical student at the Medical College of Georgia and neurosurgery residency applicant, delve into the intricate anatomy of the medial surface of the right cerebral hemisphere. We explore key structures such as the cingulate gyrus, corpus callosum, paracentral lobule, precuneus, and calcarine fissure, discussing their anatomical relationships and functional significance. This comprehensive overview aims to enhance understanding of the brain's complex architecture and its implications in neurosurgical practice.

Cortical Anatomy Pt.2- Lateral, Coronal Views

In this episode of Neurosurgery Review, I, Mustafa Farooq, a fourth-year medical student at the Medical College of Georgia and a neurosurgery applicant in this year’s match cycle, guide you through the intricate surface and internal anatomy of the brain, focusing on its right lateral view and coronal section. We begin by examining the surface anatomy of the brain’s right lateral view, highlighting key landmarks such as the central sulcus, precentral and postcentral gyri, and lateral sulcus, along with their functional significance. From motor and sensory processing in the precentral and postcentral gyri, to the cognitive and auditory roles of the frontal, parietal, and temporal lobes, we uncover the structural and functional interplay that defines the brain’s surface. Next, we explore the brain's internal structures through the lens of a coronal section. This segment delves into essential components like the corpus callosum, thalamus, basal ganglia, and ventricular system, connecting their anatomical positions to their critical roles in movement, sensory relay, and memory. Highlights include a discussion on the amygdalaand mammillary bodies within the limbic system, as well as the claustrum and its potential role in brain region coordination.

Cortical Anatomy Pt. 1- Neocortex, Superior View

In this episode of Neurosurgery Review, I, Mustafa Farooq, a fourth-year medical student at the Medical College of Georgia and a neurosurgery applicant in this year’s match cycle, take you through the intricacies of cortical anatomy, exploring the brain’s remarkable complexity and structural organization. Starting with the cerebral cortex, which contains approximately 14 billion neurons, we discuss its developmental origins from the germinal zone and its layered organization into six neocortical layers, each with distinct cells, neurotransmitters, and functions. Highlights include the role of Golgi type II cells in modulating neuronal activity, the significance of stellate and pyramidal cells, and the unique contributions of structures like the external and internal bands of Baillarger. Additionally, we examine the surface anatomy of the brain, from the longitudinal fissure dividing the hemispheres to the functional landmarks of the frontal, parietal, and occipital lobes, such as the central sulcus and precentral gyrus. This episode connects anatomical details with their functional implications, providing an essential guide for anyone looking to deepen their understanding of cortical anatomy. mufarooq@augusta.edu

Blood Supply to the Spinal Cord

Mustafa Farooq, a 4th-year MD student at the Medical College of Georgia and current neurosurgery residency applicant, dives into the high-yield anatomy of spinal cord blood supply. This episode covers the anterior and posterior spinal arteries, radicular arteries, and key vascular territories, emphasizing clinical relevance and exam-focused details. Mustafa explains the centrifugal and centripetal flow patterns, the critical role of the artery of Adamkiewicz, and vulnerable border zones, tying it all together with venous drainage and ischemia risks.
