Receptor Occupancy

Occupancy Contrast Is One Fourth

The sensing contrast is a checked difference of two occupancies. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Compare high and low occupancy

The high side binds 3/4 while the low side binds 1/2.

34−12\frac{3}{4} - \frac{1}{2}
Occupancy contrast ledgerHigh minus low occupancy becomes the sensing contrast.1/4

Subtract to get the sensing contrast

The occupancy contrast is 1/4.
