+- Convolution
+- Correlation
+- Linearity and its problems
+
+Linearization of problems is used for saving energy also by the brain.
+
+Gabor functions look like
+$
+	g (x) =  (1) / (sqrt(2 pi sigma)) exp((- (x - x_0 )^2 ) / (2 pi sigma)) "trig"(k x).
+$
+Those can be used to model response patterns of some tissues.
+
+Filter operation is always a convulution.
+
+In the brain every cell is oriented to a specific point in space.
+
+Next time we will make applications of convolutions and correlations.
