Electrocautery is the process of burning or destroying tissue by use of a small probe with an electric current running through it. It has become a routine surgical means of burning unwanted or harmful tissue and is also used to diminish or stop hemorrhaging. Its applications range from the more obvious stemming of blood flow to lesser-known applications for craniotomy, peripheral nerve repair, aneurisms and cataract extraction.
Electrochemical detector requires three electrodes like working electrode, the auxiliary electrode and the reference electrode. It responds to substances that are either oxidizable or reducible and the electrical output is an electron flow generated by a reaction that takes place at the surface of the electrodes.
Electrocorticography is a technique of recording and measuring the electrical activity of the cerebral cortex by means of electrodes placed directly on it. The purpose of the EcoG is to localize a suspected seizure focus in the cerebral cortex in patients who are candidates for surgery. It can be performed outside of surgery or during surgery. It is also used for determining neuronal thresholds.
