Introduction, between cortical structure and function. Our results may be at variance with the ideas of those physiologists who have specialized subsystems of the cortex in mind, but are not in contrast with them, as we hope to show. Our view is akin to one presented by Moshe Abeles in his monograph . (1982). It

Where is the Cortex?,iece of cortex from any mammal, and for the exclusion of almost any other piece of the brain. Thus the structural traits of the cortex in general seem to be well defined. Yet it is quite a different matter to define the limits of the cortical tissue in any particular brain, in both the topographic s

Comparison Between Synaptic and Neuronal Density,mum possible degree of dispersion of the signals emanating from one neuron, or conversely, the maximal possible convergence of signals from different sources onto one neuron. On the other hand, convergence/divergence may not be the essence of the story. If we suppose that one neuron may be connected

Comparison Between the Densities of Neurons, Synapses and Axons,ents on Golgi preparations have led to values less than half that figure. It must be noted, however, that the measurements in Braitenberg 1978b which refer to pyramidal cells (the classification of cell types will be introduced in Chap. 15) do not consider the reentrant axons of these cells. These m

Microscopic Evidence of the Spacing of Synapses on Axons,nts of synapses formed by selected axons. Our first approach was with the electron microscope (Schüz and Münster 1985), a task requiring rather tedious work on serial sections. We then discovered a short cut, permitting us to count synapses on much larger samples, and much more easily, by means of t

Statistics of the Synapses Along the Axons,he axonal swellings or boutons. This was an interesting issue for us, because on one hand we favour the view of a diffuse network of synaptic contacts between axons and dendrites, implying a homogeneous distribution of the synapses over the whole axonal tree, while on the other hand the study summar
