The chemosensitivity of unmyelinated axons can be examined by tracking the electrical threshold of the compound C-fibre action potential generated in short isolated segments of isolated sural nerve [25] and in the present study this method has been used to characterize the effect of GABA on unmyelinated axons from humans.
These are tracking the electrical activity of your heart; if the activity is moving toward the tracker, the lines will go up (this is called "positive deflection"); if the activity is moving away from the tracker, the lines will go down (this is called "negative deflection").
An equally ambitious "big brain" idea is in the works in the United States: The Obama administration is expected to propose its own project, with up to $3 billion allocated over a decade to develop technologies to track the electrical activity of every neuron in the brain.
Inside it's packed full of sensors and chips (the ones you can't eat) that track the electrical current produced by brain when the wearer moves their eye.
It was observed that by applying a magnetic field of 0.75 T perpendicular to the GC surface and tracking the variation of the electrical double layer (EDL) capacitance one can estimate the mass load on the surface of the electrode.
Many satellites launched for important purposes such as monitoring solar weather (bad solar storms can damage electrical equipment on Earth), tracking the climate and just helping people navigate are limping along in need of replacement.
Here's how it came up with those concerns: The headband's sensors track the brain's electrical signals during different phases of sleep (light, deep, REM and awake) and transmits them to the clock, which is equipped with a data chip.
Four electromechanical sun tracking systems, two axes, one axis vertical, one axis east west and one axis north south, were designed and constructed for the purpose of investigating the effect of tracking on the electrical values, current, voltage and power, according to the different loads (variable resistance).
Because of the inductive impedance caused by steel meshes in traditional reinforced ballastless track slabs, the electrical properties, primarily the rail resistance and inductance, of jointless track circuits are affected by electromagnetic induction between the slabs and the electric current in the rail.
We were, among other things, tracking electrical activity on the surface of the sun, from the far south of the Indian Ocean.
"Topography" was not quite the right word, since the STM was tracking electrical properties.
