Hey guys,
I don't want to draw you into deep technical stuff however I came across with a sentence where I saw this "deficient gain" thingy in it. Here's the sentence for you to refer:
"...Seventeen patients with acute, mainly unilateral cerebellar infarctions and an intact gain of the smooth pursuit system were compared with 11 patients with cerebellar lesions and deficient gain of sinusoidal smooth pursuit eye movements by means of lesion-mapping imaging..."
What I want to know is that does this "gain" here mean to obtain something? Are the smooth pursuit eye movements something that can be gained from somewhere or something or even somebody? If yes, does the adjective "deficient" here mean that the gaining process is somewhat inadequte so there we have a problem?
I hope I could ask my question clearly. I just need to understand the way the so-called familiar words are used in a medical context to use the insight in my further ventures
