Microscopic Evidence of the Spacing of Synapses on Axons,s 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 the light microscope (Hellwig 1990; Hellwig et al. in prep.).

Interim Discussion,s which could be interpreted in terms of cortical function, even before there was any mention of the shape of neurons and of their specific connections. Actually, we believe that some theoretical models of the cortical wiring are already excluded by the data at this stage.

Classification of Cortical Neurons,tical neurons described in the literature, we proposed a distinction between two classes, pyramidal and stellate cells., with a third class, Martinotti cells perhaps occupying an intermediate position, but well enough characterized to be kept separate. The classes were defined as follows.

Length of the Dendritic Trees,common in Golgi preparations than a complete stain of both dendrites and axons. The stain of the initial segment of the axon, in conjunction with the shape of the dendritic tree, is sufficient in most cases to confidently classify the neurons as belonging to one of our three types.

Book 19911st edition 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 Local Cortic

Essentials on systems and control to another not just by one but by any number of synapses, the numerical ratio of synapses and neurons in the tissue is an indication of how fine the tuning of the influence can be. Our personal preference for one or the other interpretation of the number of synapses per neuron will be apparent in a later section of this book.

This problem is, of course, common to many biological contexts, where the definition of a certain type (of tree, of sense organ, of society, of linguistic syntax) becomes quite elusive when put to the test of a decision procedure capable of recognizing every instance of it.
