Briefly, an un-insulated 0.127-mm 0.127-mm electungstenharpelectrodelectrolysharpenedtain a 0.5 μm tip diameter, was inserted in the DLMs (fibyr a).
In order to record the responses of GRNs from odors diluted in paraffin oil, we inserted an electrolytically sharpened tungsten electrode at the base of taste sensilla, connected to a custom-built preamplifier and further amplified (×1000) by a CyberAmp 320 amplifier (Axon Instruments, USA) using 8 dB Bessel band-pass filters from 0.1 Hz to 2800 Hz.
An electrolytically sharpened tungsten electrode was used to establish contact with pheromone sensitive olfactory sensory neurons (OSNs).
In this study, a finely sharpened tungsten electrode was used to penetrate the base of each sensillum and record the activity of OSNs contained therein.
The animal was transferred to a Faraday cage and an electrolytically sharpened tungsten electrode was inserted into the margin of the median or the left ocellus, while the reference electrode was positioned in the dorso-caudal part of the head capsule.
In vivo thalamocortical (TC) or intracortical (IC) fibers were stimulated with bipolar electrodes made of sharpened tungsten wires.
Tungsten electrodes were electrolytically sharpened, and one electrode was inserted into the joint between the first and second antennal segment while the other was simultaneously inserted into the head capsule.
For the OSN recordings, single basiconic sensilla were targeted with electrolytically sharpened tungsten electrodes to measure the aggregate electrical activity of OSNs housed in these sensilla (Kim et al., 2011).
We attempted to enlarge the opening by breaking the tip of the electrode to lower resistance, aid in filling and sharpen the penetrating edges (21).
A neural electrode array design is proposed with 3 mm long sharpened pillars made from an aluminum-based substrate.
A sharpened tungsten wire inserted into the neck musculature served as an indifferent electrode.
