These 10 animal facts will amaze you. Color blindness is most often a genetic visual deficiency that limits the colors that an individual can detect. Most people with this condition don't only see in black and white. The colors affected are usually limited to green and red, which often appear as shades of tan or brown.hese 10 animal facts will amaze you.

The duration of the QT-interval varies dependent upon how fast the heart is beating, but in normal healthy people, when the heart is beating 60 beats per minute, it is between 350 and 440 milliseconds.
A 'typical' HVPC set of parameters are illustrated in Figure 2 below. In this case the pulse duration is set at 200Âµs, the interpulse interval is set at 9800Âµs and therefore 1 cycle will take 10000Âµs to deliver (which is 10ms-milliseconds). If 1 cycle takes 10ms to deliver, the stimulation frequency will be 100Hz.t is argued (see figure 3 below, from www.nervestudy.com) that although the pulses are high voltage (typically 150-500V), they are of very short duration (microsec) and thus the actual (averaged) current flow through the tissues will be low-in the microcurrent range (microamps).
