SU-8 spike electrodes for neural signals
| Resumo: | Electrodes are widely used to record biological signals from living tissue, namely in neuroscience where researchers need to record brain signals in vivo. This paper presents a rapid low-cost prototyping technology for protocol-specific electrode designs. The suggested fabrication process combines SU-8 photoresist patterning in multiple layers with the deposition of intermediate conductive layers (in this case Au layer). The fabricated electrodes were specifically designed for an electrophysiological experiment that required simultaneous recording in the pre-frontal cortex (PFC) and stimulation in the hippocampus of the rat brain. |
