“…In the present study, NE was not detectable, but HVA as DA metabolite and 5HT and 5HIAA were detected. These results may, at least in part, reflect release of their respective neurotransmitters (Gruss and Braun, 1997;Gruss et al, 1999). Focusing on the variations in the basal values of DA content between the experiments, several studies (Saito et al, 2004;Shiraishi et al, 2010;Katayama et al, 2010Katayama et al, , 2011Erwan et al, 2012) have reported the fluctuation of monoamine contents especially in basal values of DA in the diencephalon or telencephalon in chicks.…”

“…In previously proposed methods for combining a recording microelectrode with a microdialysis probe, a tungsten needle was glued to a guide cannula of a microdialysis (Gruss et al, 1999), a silver wire was inserted into a guide cannula (Obrenovitch et al, 1994), and a microdrive of bundled electrodes was glued to a guide cannula of a microdialysis probe (Ludvig et al, 1994). These methods of simply attaching a metal needle to a guide cannula are largely invasive due to the increment of probe's volume and make it difficult to precisely position the tip of recording microelectrodes to the target.…”

“…Earlier methods inserted a recording electrode into a guide cannula (Obrenovitch et al, 1994) or attached a recording electrode to a guide cannula, which were independently fabricated (Ludvig et al, 1994; Gruss et al, 1999). Our method, in which an electrode is fabricated directly on the surface of a guide cannula, is advantageous over these earlier methods.…”

“…Thus, there is a need for new designs that offer flexibility with a tissue fixation structure. Another example is the demand for the capability to record electrical and chemical neural activities simultaneously by integrating a neural electrode with a microdialysis probe (Ludvig et al, 1994; Obrenovitch et al, 1994; Gruss et al, 1999). This requires precise patterning of recording electrodes on the non-flat surface of the guide cannula of a microdialysis probe.…”

An extensive photosensitive-polyimide (PSPI)-based method for designing and fabricating various neural electrode architectures was developed. The method aims to broaden the design flexibility and expand the fabrication capability for neural electrodes to improve the quality of recorded signals and integrate other functions. After characterizing PSPI's properties for micromachining processes, we successfully designed and fabricated various neural electrodes even on a non-flat substrate using only one PSPI as an insulation material and without the time-consuming dry etching processes. The fabricated neural electrodes were an electrocorticogram (ECoG) electrode, a mesh intracortical electrode with a unique lattice-like mesh structure to fixate neural tissue, and a guide cannula electrode with recording microelectrodes placed on the curved surface of a guide cannula as a microdialysis probe. In vivo neural recordings using anesthetized rats demonstrated that these electrodes can be used to record neural activities repeatedly without any breakage and mechanical failures, which potentially promises stable recordings for long periods of time. These successes make us believe that this PSPI-based fabrication is a powerful method, permitting flexible design, and easy optimization of electrode architectures for a variety of electrophysiological experimental research with improved neural recording performance.

“…Using separate electrodes to examine glutamate and electrophysiological signals within the same preparation has been a commonly employed method [19][20][21][22] ; however, it is problematic when the separate microelectrodes are not located within the same microenvironment. Several reports delivered external glutamate or drugs that could affect glutamate release into the rat brain and recorded only electrophysiological signal changes [23][24][25][26][27][28] ; however, this method can serve in only a limited capacity for glutamate change is not quantitative.…”

An implantable microelectrode array for simultaneous L-glutamate and electrophysiological recordings in vivo

et al. 2015

L-glutamate, the most common excitatory neurotransmitter in the mammalian central nervous system (CNS), is associated with a wide range of neurological diseases. Because neurons in CNS communicate with each other both electrically and chemically, dualmode (electric and chemical) analytical techniques with high spatiotemporal resolution are required to better understand glutamate function in vivo. In the present study, a silicon-based implantable microelectrode array (MEA) composed of both platinum electrochemical and electrophysiological microelectrodes was fabricated using micro-electromechanical system. In the MEA probe, the electrophysiological electrodes have a low impedance of 0.018 MΩ at 1 kHz, and the electrochemical electrodes show a sensitivity of 56 pA µM −1 to glutamate and have a detection limit of 0.5 µM. The MEA probe was used to monitor extracellular glutamate levels, spikes and local field potentials (LFPs) in the striatum of anaesthetised rats. To explore the potential of the MEA probe, the rats were administered to KCl via intraperitoneal injection. K + significantly increases extracellular glutamate levels, LFP low-beta range (12-18 Hz) power and spike firing rates with a similar temporal profile, indicating that the MEA probe is capable of detecting dual-mode neuronal signals. It was concluded that the MEA probe can help reveal mechanisms of neural physiology and pathology in vivo.
