Development of a High-Tc SQUID-Based System for Neurophysiology Studies In-Vitro

Paper i proceeding, 2006

In this paper we report on the development of a system based on a high-T c SQUID (HTS) sensor for measurements of the neuromagnetic field generated by neurons inside tissue slices. SQUIDs have successfully been measured inside the system. The system white noise level is lower than 7 pT/Hz 1/2 , which is only slightly higher than previously reported 4.5 pT/Hz 1/2 for the same kind of SQUID measured inside a superconducting shield. © 2006 IOP Publishing Ltd.
