The outermost layer is the dura mater. The middle layer is the arachnoid mater. The inner layer is the pia mater. The epidural space is the space between the vertebral column and the dura mater. There is only a 'potential' epidural space in the skull. The subdural space is the space between the dura mater and the arachnoid mater. The subarachnoid space is the space between the arachnoid mater a...

Introduction The external membrane which invests the brain is called the cranial dura mater. It consists of a periosteal layer, which is rich in blood and lymphatic vessels and nerves, and an inner layer named the meningeal layer. At certain places the periosteal and meningeal layers are separated to form the dural venous sinuses. This is the typical description of the cranial dura mater [1–15]...

BACKGROUND Although reossification of large calvarial defects is possible in children, adults lack this tissue engineering capacity. In this study, the authors compared the differences in gene expression between juvenile and adult dura mater using a mouse cDNA microarray with 42,000 unique elements. METHODS Non-suture-associated parietal bone was harvested from 6-day-old and 60-day-old mice. ...

Polysaccharide from Dura mater By Yoshiharu Saito and Koh-Iti Turumi (齋 藤 義 治) (鶴 見 膠 一) From the Department of Biochemistry, Fukushima Medical College, Fukushima (Received for publication, October 10, 1954) Chemical studies of dura mater has not as yet been accomplished. Histologicaly dura mater is composed of connective tissue. We examined the tissue histochemically by periodic acid oxidation...

In vivo insertion experiments are essential to optimize novel neural implants. Our work focuses on the interaction between intact dura mater of rats and as-fabricated single-shaft silicon microprobes realized by deep reactive ion etching. Implantation parameters like penetration force and dimpling through intact dura mater were studied as a function of insertion speed, microprobe cross-section,...

The physiopathology of postdural puncture headache (PDPH) is most likely multifaceted (1, 2). Understanding the mechanisms through which some subjects develop PDPH may help in the development of PDPH-prevention strategies. In addition, identifying risk factors in susceptible individuals may help develop forms of anesthesia other than spinal anesthesia for preventing dura mater/arachnoid perfora...

BACKGROUND Idiopathic spinal cord herniation (ISCH) is a rare condition and its pathogenesis remains unclear. The purpose of this case report is to present an ISCH case with dorsal subarachnoid septum suggesting the pathogenesis of ISCH being adhesions from preexisting inflammation. METHODS Single case report. RESULTS A 60-year-old woman presented with Brown-Séquard syndrome below the level...

A case of myelomatous involvement of the dura mater is reported. The patient presented with blurring of vision in the right visual field and left sided facial numbness. A magnetic resonance imaging scan of the head revealed extensive infiltration of the dura mater. Cerebrospinal fluid (CSF) analysis showed no plasmacytosis and although there was a raised CSF protein concentration, no paraprotei...

An in vitro experimental study of the control of the human dura mater optical properties at administration of aqueous solutions of glucose and mannitol has been presented. The significant increase of the dura mater optical transmittance under action of immersion liquids has been demonstrated. Diffusion coefficients of glucose and mannitol in the human dura mater tissue at 20 degrees C have been...
