multiple electrode

Depending on their design, multiple electrodes of differing lengths can be used with one holder.

Carefully, they fitted the multiple electrodes of the electro-encephalograph recorder to his skull.

This difficulty was overcome by using multiple electrodes.

He said: “Once it has multiple electrodes ... the robot should be able to zoom right in.

No evidence for supernormal conduction within the ventricular wall could be obtained by multiple electrode recordings.

Thus the spike sorting using multiple electrodes is better than sorting based simply on waveform shape.

To address this issue some companies have designed catheters that have multiple electrodes spaced out along the catheter for larger areas.

Multielectrode arrays are also used, in which multiple electrodes are arranged in an array.

Electrical resistivity imaging uses an automatic switching unit and multiple electrode array gathering high resolution data sets in short periods of time.

Multiple electrodes record different waveforms for each individual spike elicited by the neurons in the vicinity of the electrodes.

Others have multiple electrodes stimulating differing positions within the heart to improve synchronisation of the lower chambers (ventricles) of the heart.

EEG refers to the recording of the brain's spontaneous electrical activity over a short period of time as recorded from multiple electrodes placed on the scalp.

Electrophysiological activity from clusters of neurons in the hippocampus was then recorded using multiple electrodes, made from fine wire, implanted in the rats' brains.

Surface EMG can be recorded by a pair of electrodes or by a more complex array of multiple electrodes.

During a second treatment, Mr. Taussig was wired with multiple electrodes and fitted with a nose mask that applied continuous positive air pressure down his respiratory tract.

• Research collaboration with McMaster University on the development of tuneable multiple electrode, fabry perot and distributed feedback semiconductor lasers for optical communications (1999-2001).

DC or AC power can be used, and combinations of DC and AC are common on multiple electrode systems.

Both EEG and ERPs may be recorded from multiple electrode sites across the scalp, providing a topographic picture or "map" of on-going brain activity.

Improvements in technology have made it possible to now place multiple electrodes in the olfactory tubercle and record from anesthetized and even awake animals participating in behavioral tasks.

The functional role of synchronized oscillatory activity in the brain was mainly established in experiments performed on awake kittens with multiple electrodes implanted in the visual cortex.

Instead, a thin lead with multiple electrodes is implanted in the globus pallidus, nucleus ventralis intermedius thalami (Vim) or the subthalamic nucleus and electric pulses are used therapeutically.

The researchers compared EEG signals from multiple electrodes placed on the children’s scalps; if two or more signals, or waves, rose and fell in unison, it indicated that the brain regions were tightly connected.

The straightforward way to do this is to sweep the voltage on a single electrode, but, for a number of reasons, configurations using multiple electrodes and/or exploring only a part of the characteristic are used in practice.

Miguel Nicolelis, a professor at Duke University, in Durham, North Carolina, has been a prominent proponent of using multiple electrodes spread over a greater area of the brain to obtain neuronal signals to drive a BCI.

This is often referred to as multiple electrode strategy, and is most common when the tool electrode replicates in negative the wanted shape and is advanced towards the blank along a single direction, usually the vertical direction (i.e. z-axis).
