The dura mater is the outermost meningeal layer.硬脑脊膜是最外面的一层脑膜。 Certain surgical procedures penetrate or involve the risk of penetrating the dura mater. Electrodes were lowered through the dura into the thalamus. A subdural haematoma is a collection of blood between the brain and dura.

After the dura mater was excised, the pia mater was eliminated under the microscope control with a tungsten wire sharpened to 1-2 mm. The dura mater was dissected for visualization of the injection zone. Intra-cranial pressure was reduced by release of the cerebrospinal fluid through an opening of the dura mater at the foramen magnum. The dura mater was carefully removed in order not to damage the dorsal sagittal sinus. The dura was reflected to expose the cortex. The dura was closed with 9-0 suture, muscle reapposed and skin closed with wound clips. After removing the dura, the chamber was filled with silicone oil and sealed with a round glass coverslip. The dura mater was sewn back and regrew over the electrode array. The dura mater was removed above the auditory cortex and at a position vertically above the auditory thalamus. The dura mater overlying both regions of exposed central nervous tissue was cut and warm mineral oil applied to prevent drying. The dura was resected and the cortex was aspirated down to white matter. Due to the angle of entry, the majority of recordings were made beneath intact dura, with generally good stability. The dura was excised above the injection site using a 30-gauge needle. A craniotomy was made, the dura was retracted to expose the cortex and the needle was lowered to the desired location under microscopic guidance.
