Design, realization, and testing of a SPR biosensing system for wine quality monitoring
A complete innovative and portable, for on-field operation, Surface Plasmon Resonance (SPR) biosensing system for wine quality monitoring was designed, realized and tested; the system takes advantage of the innovative module Spreeta™, an integrated transducer designed by Texas Instruments able to recognize the Surface Resonance Phenomena and to represent it through electrical signals. The system, based on an 8 bit microprocessor board, acquires through a 12 bit A/D converter, elaborates and sends to a PC data from the Spreeta™ sensor. A proprietary high-level software calculates the refractive index related to biological solution flowing on the surface sensor and lets to detect suitable sub…
Illusory contours and specific regions of human extrastriate cortex: evidence from rTMS.
Functional magnetic resonance imaging studies showed that perception of illusory contours is associated with extrastriate cortex activation prevailing on the right side. 1 Hz repetitive transcranial magnetic stimulation (rTMS) is able to induce lasting inhibition of cortical activity. The objective of the study was to investigate the role of extrastriate cortex in illusory contour perception inducing 1 Hz rTMS interference in healthy subjects. Eight healthy subjects underwent 1 Hz rTMS (600 pulses) through a figure-of-eight coil over right and left occipital cortex (O1 and O2 of 10/20 EEG system); sham magnetic stimulation on the same sites and right motor cortex rTMS (in three subjects) we…
Modulatory effects of low- and high-frequency repetitive transcranial magnetic stimulation on visual cortex of healthy subjects undergoing light deprivation.
The aim of the present study was to explore further the effects of light deprivation (LD) on visual cortex excitability. Healthy subjects reporting reliable induction of phosphenes by occipital transcranial magnetic stimulation (TMS) underwent 60 min of complete LD. Phosphene threshold (PT) was measured before (T0), after 45 min (T1) and 60 min (T2) of LD, and then every 10 min after light re-exposure until recovery to T0 values. Repetitive TMS (rTMS) (at 1 or 10 Hz) was applied in separate sessions during the last 15 min of LD. PTs significantly decreased after 45 min of LD. rTMS differentially modified the effects of 60 min LD on PTs depending on stimulation frequency. One hertz rTMS did …
