✦ Synopsis

Abstract

Techniques are described for fabrication of electrode arrays for stimulation and/or recording from a human cerebral cortex. These arrays may be neurosurgically inserted (with or without a Penrose drain) in the course of a conventional craniotomy or craniectomy, and are easily removed without reopening the ineision. Termination of the connecting wires in a special percutaneous pedestal has also permitted chronic implantation. The contacts and connecting wires are made of pure platinum embedded in a Teflon ribbon‐cable matrix. The choice of materials combines biological acceptability, electrochemical stability, and integrity of the insulation, but imposes special fabrication procedures.

## Abstract The passive biocompatibility of silicon‐based electrode arrays was studied in feline cortical tissue. Three types of arrays were used: uncoated, coated with polyimide, and coated with polyimide over an adhesion promoter. Fifteen arrays were implanted for 24 h to determine early tissue r

Superconducting tunnel junction (STJ) detectors have a fast time response and a low threshold to detect such quanta as phonons. These characteristics are advantageous to their applications in mass spectrometry for large molecules. However, one drawback is small active area, which cancels out the hig
