Now you collect a series of intensity/response curves, varying the indentations per second. Make a tuning curve. Estimate the sweet spot.

You are making an electrical recording from a sensery receptor, stimulating it by vibrating at 500 indentations/sec, but varying the intensity (depth of indentation). Make an intesity/ response curve from the following data: 10 micrometer indentation 30 micrometer indentation 50 micrometer indentation time -> (1 sec) time -> (1 sec) time -> (1 sec) 70 micrometer indentation 90 micrometer indentation 110 micrometer indentation time -> (1 sec) time -> (1 sec time -> (1 sec) 10 8. Estimate the threshhold: 50 indentation depth (micrometers) 100 response (spikes/sec) Vmembrane Vmembrane Vmembrane Vmembrane
