“…The development of fiber-dissecting techniques has helped generations of neurosurgeons to develop their skills prior to operation. In recent years, the interest for this approach has risen again ( Costa et al, 2018 ; Altieri et al, 2019 ; Grzegorczyk et al, 2019 ; Dziedzic et al, 2023 ). The combination of classical, neuroanatomical, fiber-dissection techniques and more advanced neuroradiological approaches such as diffusion tensor imaging and fiber tractography, have broadened the understanding of several white-matter connections ( Holl et al, 2011 ; Akakin et al, 2014 ; Sarubbo et al, 2015 ; Meola et al, 2016 ; Burks et al, 2017 ; Goryainov et al, 2017 ; Pascalau et al, 2018 ; Flores-Justa et al, 2019 ; Shah et al, 2019 ; Dziedzic et al, 2021a , 2022 ; Rauch et al, 2021 ), even leading to the discovery of novel structures ( Shinohara et al, 2020 ).…”

The proper preservation of human brain tissue is an indispensable requirement for post-mortem investigations. Neuroanatomical teaching, neuropathological examination, neurosurgical training, basic and clinical neuroscientific research are some of the possible downstream applications of brain specimens and, although much apart from one another, proper tissue fixation and preservation is a common denominator to all of them. In this review, the most relevant procedures to fixate brain tissue are described. In situ and immersion fixation approaches have been so far the most widespread ways to deliver the fixatives inside the skull. Although most of them rely on the use of formalin, alternative fixative solutions containing lower amounts of this compound mixed with other preservative agents, have been attempted. The combination of fixation and freezing paved the way for fiber dissection, particularly relevant for the neurosurgical practice and clinical neuroscience. Moreover, special techniques have been developed in neuropathology to tackle extraordinary problems, such as the examination of highly infective specimens, as in the case of the Creutzfeldt-Jakob encephalopathy, or fetal brains. Fixation is a fundamental prerequisite for further staining of brain specimens. Although several staining techniques have been developed for the microscopical investigation of the central nervous system, numerous approaches are also available for staining macroscopic brain specimens. They are mostly relevant for neuroanatomical and neuropathological teaching and can be divided in white and gray matter staining techniques. Altogether, brain fixation and staining techniques are rooted in the origins of neuroscience and continue to arouse interest in both preclinical and clinical neuroscientists also nowadays.

“…

Occipital lobe epilepsy is a debilitating condition, and surgical resection has been effective, though challenges arise because of the cortex's function. [1][2][3][4][5][6][7] Approximately 57% of patients with normal vision experience new visual field deficits postoperatively. 8 A combined approach of resection and responsive neurostimulation (RNS) could aid in decreasing the visual field area severed and the disability tied to it while obtaining seizure freedom.
