Application of DNQX, an AMPA antagonist, blocked all spontaneous activity, suggesting that the activity is excitatory and mediated through glutamate receptors. Expand
Enhanced infrared neural stimulation using localized surface plasmon resonance of gold nanorods.
An advanced optical activation of neural tissues is demonstrated using pulsed infrared light and plasmonic gold nanorods, which can increase a neural responsivity and lower a threshold stimulation level significantly, thereby reducing a requisite radiant exposure and the concern of tissue damage.

  • 14 June 2012
The first attempt to use a flexible material, liquid crystal polymer (LCP), as a substrate for a depth-type neural probe is reported, offering a controllable stiffness vs. flexibility and compatibility with thin-film processes in addition to its inherent characteristics such as high reliability and biocompatibility.

Cell-based olfactory biosensor using microfabricated planar electrode.
This cell-based olfactory biosensor, which uses a microfabricated planar electrode for detection, would be useful for screening specific ligands for binding to orphan olfaction receptors. Expand

  • 1 September 2013
The principles, the instrumentations and in vivo applications of those optical signal measurements are described and two most popular activity-dependent fluorescent probes, calcium indicators and voltage-sensitive fluorescent proteins will be examined in this review. Expand
Enhancement of cellular olfactory signal by electrical stimulation
It is demonstrated that electrical stimulation can enhance cellular activity and increase the response signal for detecting ligand binding and can be used as a novel method in the field of versatile cell‐based biosensors for detection of specific odorants. Expand

Modiolus-Hugging Intracochlear Electrode Array with Shape Memory Alloy
A shape-memory-alloy-(SMA-) embedded intracochlear electrode which gives a straight electrode a curved modiolus-hugging shape using the restoration force of the SMA as triggered by resistive heating after insertion into the cochlea is proposed. Expand
Photothermal activation of astrocyte cells using localized surface plasmon resonance of gold nanorods.
It is presented that NIR stimulation of micro-second duration combined with gold nanorods (GNRs) efficiently produces stronger Ca2+ transients of astrocytes, which seems to be associated with a local heat generation by photothermal effects of GNRs. Expand
