Metastatic involvement of the leptomeninges by malignant gliomas, such as glioblastoma multiforme and medulloblastoma, is not unusual. However, gliomas grossly appearing to arise in the lepto-meninges are rare, and may assume one of two forms: (1) the meningeal tumour may be entirely extracerebral and have no demonstrable connexion with the underlying neuraxis, or (2) it may grow largely in the...

Functional and neuroanatomical asymmetries are an important characteristic of the human brain. The evolution of such specializations in the human cortex has provoked great interest in primate brain evolution. Most research on cortical sulci has revolved around linear measurements, which represent only one dimension of sulci organization. Here, we used a software program (BrainVISA) to quantify ...

Autism spectrum disorder (ASD) is characterized by deficits in social functioning and language and communication, with restricted interests or stereotyped behaviors. Anatomical differences have been found in the parietal cortex in children with ASD, but parietal subregions and associations between Sylvian fissure (SF) and parietal anatomy have not been explored. In this study, SF length and ant...

We explored cortical fields on the upper bank of the Sylvian fissure using functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) to measure responses to two stimulus conditions: a tactile stimulus applied to the right hand and a tactile stimulus with an additional movement component. fMRI data revealed bilateral activation in S2/PV in response to tactile stimulation alon...

The pterional craniotomy is one of the most frequently surgical approaches used in neurosurgery and currently it has become a mainsteam. It allows excellent microsurgical exposure of anterior and posterior regions of the arterial circle of Willis, supra and paraselar regions, the superior orbital fissure of sphenoid bone, cavernous sinus, orbit, temporal lobe, midbrain and the frontal lobe. Lik...

Background and Aim: In the present study, the cerebral surface landmarks in human fresh autopsy specimens were investigated. Methods and Materials/Patients: Totally, 37 fresh adult autopsy human brain specimens from the Rasht Forensic Medicine Center were enrolled. Four specimens were excluded because of some traumatic injuries to cerebral cortex. Demographic information of all cases was obt...

BACKGROUND Fetal brain development is a complicated process that continues throughout pregnancy. Fetal sulcus development has typical morphological features. Assessment of fetal sulcus development to understand the cortical maturation and development by prenatal ultrasound has become widespread. This study aimed to explore a reliable method to assess cortical sulcus and to describe the normal s...
