Array electrodes are a promising technology that is likely to bring transcutaneous electrical stimulation (TES) a step forward. The dynamic adaptation of electrode size and position helps to simplify the use of electrical stimulation systems and to increas ...
In bioelectric recordings, an electrode-skin impedance mismatch leads to a reduced common-mode rejection ratio (CMRR) of the amplifier. For this reason, the impedance of each individual electrode-skin contact is usually measured prior to a recording. The m ...
Dopamine replacement therapy is useful for treating motor symptoms in the early phase of Parkinson's disease, but it is less effective in the long term. Electrical deep-brain stimulation is a valuable complement to pharmacological treatment but involves a ...
This paper describes the fabrication of polyimide-based microelectrodes with embedded fluidic microchannels. The thin-film structures combine for the first time a fluidic system with microelectrodes for recording and stimulation of biological signals on a ...
Technological innovations in the fields of biomedical optics and electronics have lead to an extremely high level of miniaturization. These steps opened important perspectives to interface optoelectronic instruments with cellular systems. In this frame, a ...
Understanding how the information is coded in large neuronal networks is one of the major challenges for neuroscience. A possible approach to investigate the information processing capabilities of the neuronal ensembles is given by the use of dissociated n ...
Light stimulation of neurons is a promising approach for investigating the molecular mechanisms at the basis of neuronal physiology and plasticity. In particular, flash photolysis of caged compounds offers the unique advantage of allowing to quickly change ...
We report on the microfabrication and testing of a chip- scale plasma light source. The device consists of a stack of three anodically bonded Pyrex wafers, which hermetically enclose a gas-filled cavity containing interdigitated Aluminum electrodes. When t ...
The unique properties of single-wall carbon nanotubes (SWNTs) and the application of nanotechnology to the nervous system may have a tremendous impact in the future developments of microsystems for neural prosthetics as well as immediate benefits for basic ...
We present a new flexible microfabricated polyimide-based platinum array of 3D “tissue coupled electrodes” (TCEs) applied for local stimulation of the chick retinal photoreceptor layer and simultaneous patch clamp recording from a single retinal ganglion c ...
