The Boolean AND function has a zero (0) as first entry in y collumn instead of the one (1). The dispalyed function is the Boolean XOR function (or non-XOR, depending on the translation of 0/1 to true/false).

Equation (3.20) on the right should read u(v>30) = u+d

The numerical example is not correct. The sum of the synaptic events is binominal distributed with mean 10000*0.005=50 and variance 10000*0.005*(1-0.005), which is reasonable well approximated by a Gaussian with this mean and variance.

Important for the argument here is that the `noise' in the average is much less than N times the 'noise' of the single events since some of the fluctuations will go in different directions and will chancel out each other. More formally, the sum of any random numbers with means mu and variances sigma^2 is a random number with mean N*mu and variance N*sigma. Thus, the variation in the background becomes less important when many synapses are involved since the standard deviation of the sum of random variables only scales with the square root of the number of variables.

This second derivative in the example is (x-t). The term should be substituted in equation B.15 instead of th term (1-x).
