Novel dual microelectrode probe for the simultaneous visualization of local Zn<sup>2+</sup> and pH distributions in galvanic corrosion processes
2017, Corrosion ScienceCitation Excerpt :Unfortunately, this approach exhibits the disadvantage of employing two individual probes instead of one, enhancing the convective effects due to the motion of the microelectrodes while measuring, and demanding reproducible control of the inter-electrode distance by the operator. These drawbacks can be better addressed using multi-barreled microelectrodes similar to those employed in iontophoresis applications by life scientists [16–19]. Though a multi-channel assembly containing a gallium microelectrode was employed in potentiometric SECM studies for setting the tip-sample distance about 20 years ago [20], multi-barreled electrodes have not been employed in SECM investigations for the simultaneous visualization of the local concentration distributions of two ionic species produced during the complex corrosion processes until now.
Duration sensitivity of neurons in the primary auditory cortex of albino mouse
2016, Hearing ResearchCombining pharmacology and whole-cell patch recording from CNS neurons, in vivo
2013, Journal of Neuroscience MethodsCitation Excerpt :Thus far, however, discrete pharmacological manipulations e.g., reversibly blocking receptors, in vivo, have largely been restricted to extracellular recordings of single or multiunit activity. In this method, a multibarrel pipette is typically ‘piggybacked’ to an extracellular recording electrode (Havey and Caspary, 1980). After isolating a single unit and characterizing its responses, drugs are delivered iontophoretically.
Selectivity and persistent firing responses to social vocalizations in the basolateral amygdala
2012, NeuroscienceCitation Excerpt :In five animals, one or more excitatory drugs (glutamate (GLU); aspartate (ASP); bicuculline (BIC)) (GABAa receptor antagonist) were iontophoretically injected into MG in order to increase auditory excitation to the amygdala. In these animals, single neuron recordings were obtained from MG using a micropipette electrode (physiological saline) mounted on a five-barrel pipette (Havey and Caspary, 1980). The tip of the multibarrel pipette was broken to a diameter of 30 μm, and the unbroken tip of the single electrode extended 10–20 μm beyond the multibarrel pipette.
