The relationship of number of sensory trials to responses showing statistically significant differences

Number of trials	% Significant subthreshold neurons
5	4 (n = 10/233)
10	9 (n = 22/233)
15	12 (n = 27/233)
20	13 (n = 31/233)
25	16 (n = 37/233)

For the full population of unimodal neurons (n = 233), a series of paired ‘t’-tests were conducted that included a progressive increase in the number of trials (from 5 to 25). Note as the number of trials increased the proportion of neurons showing response changes that met the statistical criterion also increased
