Neurochemical pathways involved in brain physiology or disease pathogenesis are mostly
unknown either in physiological conditions or in neurodegenerative diseases. Nowadays
the most frequent usage for biotelemetry is in medicine, in cardiac care units or step-down
units in hospitals, even if virtually any physiological signal could be transmitted (FCC, 2000;
Leuher, 1983; Zhou et al., 2002). In this chapter we present a wireless device connected with
microsensors and biosensors capable to detect real-time variations in concentrations of
important compounds present in central nervous system (CNS) and implicated in brain
energetic metabolism (Bazzu et al., 2009; Calia et al., 2009)
