The fish counter works by using electrodes attached to a weir at the pumping station.
It supplies tapes, dressings, wound closure products, casting materials, electrodes, stethoscopes, drapes and masks.
By knowing which electrodes were triggered, it is possible to determine what agent is present.
As they position the electrodes, the doctors are able to monitor the sound of neurons firing.
From there it travels to one of the electrodes and a current is thus generated.
ECONOMIST: A new type of cell may bring ��solar�� energy indoors
The electrodes are 1.27 millimeters in diameter, "about the thickness of angel hair pasta, " Gross explained.
One experiment involved two groups of people with fake electrodes attached around their lips and chins.
FORBES: Ten Ways To Ease Painful Mood Swings Without Taking Pills
High-density optical fiber arrays would offer more, and thinner, probes for neuronal exploration than bulky electrodes.
The patent suggests a pair of electrodes, attached to the skin, for each device.
To investigate why this might be happening, the researchers attached electrodes to the insects' antenna.
Instead of gauging their responses with pellets of food, he probed them with recording electrodes.
Instead, one of the electrodes dipped into the calcium chloride is made of solid titanium dioxide.
The group hopes to implant electrodes that can detect electrical activity as well as stimulate it.
The researchers recorded the rats' brain activity using electrodes as the animals completed the task.
MSN: Goggle-wearing rats show link between learning, rewards
Dr Gross, a surgeon, is already skilled at implanting stimulating electrodes into human brains.
One of the electrodes is composed of metallic lead, the other of porous lead dioxide.
Electrodes are then used to stimulate the damaged area to replicate the action of the undamaged cells.
The technology is made possible by tiny strands of zinc oxide that are sandwiched between two electrodes.
Researchers attached electrodes to the heads of 23 children, just over half of whom had photosensitive epilepsy.
The person would hold the device vertically over their breastbone and position the electrodes on their chest.
The other part of the research will consider where in the brain the electrodes should be placed.
The pinlike electrodes, which protrude into the brain's gray matter, picked up signals from the neurons nearby.
Today's electrodes do not reach very far into the spiral, which limits the perception of low frequencies.
The recording electrodes can be carried by a skull cap, and nothing has to penetrate the skin.
Depending on the configuration of the ions, the current between the electrodes will flow in different ways.
In the Argus II, the newer generation device, the surgery takes two hours and involves 60 electrodes.
Using a technique developed using primates, Professor Aziz drilled two tiny holes into Sean's head and inserted electrodes.
The device is small enough to implant into the middle ear with electrodes connected to the inner ear.
Chemical electrodes of this sort can store a lot more energy than the static electricity of a capacitor.
If the electrodes are then connected by a wire, a current will flow from one to the other.
