On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Implantation of an Electrode Assembly in a Mouse Brain for Electrophysiological Recording

This video demonstrates a technique for implanting an electrode assembly into a mouse brain. The assembly contains bipolar electrodes to record activity from the hippocampus and a reference electrode to obtain baseline activity from the cerebellum. An anesthetized mouse is placed on a stereotaxic frame, and the electrode assembly is implanted in the target brain region. The animal is then allowed to recover before performing electrophysiological recording.

Whole-Mount In Situ Hybridization

Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...
FAQs
Precise placement helps establish consistent conductive contact between the electrode and the intended biological target or recording system. This consistency supports more dependable electrophysiological recordings, stimulation responses, and bioelectronic measurements. Small placement differences can make comparisons between samples less reliable, particularly when studying complex preparations with spatially variable electrical activity.
Physical fixation limits electrode movement during an experiment, helping preserve the intended electrical interface. Reduced movement can decrease signal distortion and lower the risk of disturbing or damaging the biological preparation. Stable fixation therefore supports cleaner measurements and makes observed changes more likely to reflect biological activity rather than shifting contact.
Reproducible mounting keeps electrode position and contact conditions as consistent as possible across samples or experimental sessions. That consistency allows researchers to compare electrophysiological responses, stimulation effects, or bioelectronic measurements with greater confidence. Without it, differences in placement, movement, or contact stability may complicate interpretation and weaken comparisons.
A basic procedure first positions the electrode relative to the biological tissue, cells, or recording system, then secures it so the contact remains stable during measurement or stimulation. The mounting arrangement should be checked for reliable contact, limited movement, and minimal disturbance to the preparation before collecting experimental data.
Researchers use electrode mounting when an experiment requires stable electrical contact for electrophysiological recording, electrical stimulation, or bioelectronic measurement. The approach is relevant whenever electrode movement or inconsistent placement could affect the outcome. It can support studies of cells, tissues, and other biological preparations whose electrical behavior must be measured or controlled.
Stable mounting is especially relevant to excitable cells, neural tissue, and other electrically active biological preparations. In these systems, dependable contact helps researchers record activity or apply stimulation while limiting measurement variability caused by movement. Consistent mounting also supports comparisons across complex samples, where changes in electrode position could otherwise influence the measured response.
