BCIA Neurofeedback Exam: Demos study guide Day 2 with Complete Solutions Describe how electrical activity coming from the scalp is transformed into the EEG - Correct Answer Electrodes detect signals (in microvolts) coming from the scalp that are amplified and transformed via digital or analog processing. The EEG is an analog representation of electrical activity coming from the scalp. Morphology - Correct Answer The visible shapes and contours of the EEG waveform that give its visual appeara...

What time constant would be the most effective for cutting out low frequency noise from your SSEP cortical responses? - Answer- Answer: 10 mS SSEP cortical responses are in the typical frequency range of 100-200 Hz. That being said, let's see what time constant would give us a good Low Frequency Filter. Remember LFF filters out everything below the cut off frequency and passes higher frequencies. Formula to know: Cut off Frequency = 1 / Time Constant (tc) 1/.01 s = 100 Hz 10 ms = ...
