When stimulus delivery technology is not properly shielded, the electromagnetic acoustic transducer may induce the stimulus directly into the electrodes. This is known as a stimulus artifact, and researchers and clinicians seek to avoid it, as it is a contamination of the true recorded response of the nervous system.
A stimulus (consisting here of a checkerboard with random pixels) is presented, and spikes from the neuron are recorded. The stimuli in some time window preceding each spike (here consisting of 3 time bins) are selected (color boxes) and then averaged (here just summed for clarity) to obtain the STA.
The vest is a wearable force-feedback device that monitors an audio signal and uses electromagnetic actuator technology to convert bass sound waves into vibrations that can represent such actions as a punch or kick. The vest plugs into the audio output of a stereo, TV, or VCR and the audio signal is reproduced through a speaker embedded in the ...
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
In perceptual psychology, a sensory cue is a statistic or signal that can be extracted from the sensory input by a perceiver, that indicates the state of some property of the world that the perceiver is interested in perceiving.
No matter which iPhone you use, you’ll invariably deal with a bad or no signal at some point. Kim Komando offers 5 ways to boost signal strength.
A three-stimulus oddball task is exactly like the two-stimulus oddball task, except that in addition to the targets and standards, an infrequent, deviant stimulus such as the letter "D" will appear. These are often known as deviant standards, because they are not the target of the task but they differ from the regular standard.
A check from the Internal Revenue Service is set to make the end of the holiday season a little greener for one million taxpayers. About $2.4 billion worth of stimulus checks will be distributed ...
