The division of the cerebrum into 5 lobes is widely accepted in the scientific community. Despite this, a history of the lobes of the brain has not been discussed in the literature. Therefore, this article recounts this history with emphasis on the contributions of Thomas Willis (1664), Felix Vicq d'Azyr (1796), Johann-Christian Reil (1796), François Chaussier (1807), and Louis Pierre Gratiolet and François Leuret (1857) into one of the most widely accepted concepts in neuroanatomy.

To clarify the safe limit of shortening of the spinal cord in thoracolumbar bivertebral column resection in a goat model. ⋯ The safe limit of shortening distance of the bivertebral column resection was roughly equal to 127.6% of the mean osteotomy vertebral height and 57.1% of the initial osteotomy gap height with good correlation. Moreover, the safe limit of shortening distance of the bivertebral column resection was longer than that in single vertebral column resection. Increasing the number of vertebrae resected may prevent spinal cord injury because of excessive shortening.

The usefulness of endoscopic procedures for chronic subdural hematoma (CSDH) has been described, but the indications in patients of very advanced age have not been analyzed. The aim of this study was to evaluate the feasibility, safety, and usefulness of introduction of an endoscopic procedure for such patients. ⋯ An endoscopic procedure for CSDH can be safely indicated and useful even in patients aged ≥85 years. However, clinicians should carefully select the patients based on clinical information associated with risk factors for recurrence.

Comparative Study Observational Study
Mechanical thrombectomy for basilar artery occlusion compared with anterior circulation stroke: Mechanical thrombectomy for basilar artery occlusion.
To investigate the clinical effectiveness of mechanical thrombectomy (MT) for basilar artery occlusion (BAO) and to ascertain whether outcomes for patients with BAO were comparable to those with anterior circulation large vessel occlusion (ACS). ⋯ MT may be considered the standard care for patients with BAO. OTR was the only common significant predictor for favorable outcomes in both patient cohorts.

The main aim of this study placed on cadavers was to compare the data related to geniculate ganglion (GG) dehiscence and dimension obtained from computed tomography (CT) with dissection values. ⋯ Our findings based on dissection data suggest that radiologic evaluation of dehiscent GG detection might be erroneous by 25%, which highlights that surgeons should be careful when lifting the dura to prevent GG injury during middle cranial fossa surgical approaches. On the other hand, there was no statistical difference between CT and dissection measurements related to GG dimension.
