In his research on experimental re-innervation and regeneration, de Castro produced several of his most memorable histological preparations and drawings reflecting the diversity of cells and the complex relationships between neurons Figure 2 ; de Castro, , The publication of these intense and meticulous studies had important consequences.

Some of them are easily tangible. This recognition did not weaken: it would last until the death of Cajal in and would determine several of the milestones in the scientific trajectory and human life of Fernando de Castro.

First works of Fernando de Castro in the structure of the peripheral nervous system. The typewritten figure legend in Spanish for the defense of the thesis is conserved for the reader, as well as the signature from de Castro at that time. This figure was published in de Castro This schema was published in de Castro c , The Second Conquest: The Fine Structure of Autonomic Ganglia Undoubtedly impelled by the success of his research on the histology of the human somatic sensory ganglia, as well as by the evident lack of studies with neurofibrillary methods at that time, Fernando de Castro re-assumed a research line which he briefly explored in the very first years of his scientific career de Castro, : a serious study of the histology of autonomic ganglia.

This research line can be considered as completed with the publication of a monograph and a series of shorter articles which includes maybe the most important comparative study between mammalian species including primates and humans to that date de Castro, a , b , , , although important morpho-functional observations derive from works mainly devoted to other subjects than sympathetic ganglia for details about the latter three studies, see below de Castro, a , b , , ; de Castro and Herreros, ; Figure 3.

De Castro also affirmed that these dendritic nests, far from being accidental arrangements, are receptive sites for specific synaptic contacts from preganglionic fibers de Castro, b. In each ganglion cells of these three types are intermingled and distributed in an apparent arbitrary way de Castro, b , , , and each type of preganglionic fiber contacts exclusively one type of ganglionic cell Billingsley and Ranson, ; de Castro, a , a , b , , which coincides with electrophysiological recordings showing four different potential waves in sympathetic ganglia Bishop and Heinbecker, ; Eccles, a , b , c.

Thus, the sensory nature of these fibers, as proposed originally by Dogiel, could be discarded. Posterior denervation studies demonstrated that the number of intraganglionic synapses is significantly larger than that of terminal boutons de Castro and Herreros, Developmental evidence drove de Castro to suggest that the apparent disorder and arbitrary distribution of ganglionic cells derive from germinative centers or spheres disseminated within the ganglia de Castro, a , a , b.

For example, he clearly stated that the ganglia are literally invaded by mesenchymal structures that lie interposed between the ganglionic neuronal components somata, dendrites, axons. In the ganglia the Schwann cells behave as the oligodendrocytes in the CNS, but de Castro also suggested that expansions emanated by Schwann cells form the intermediate portions of synapses, i.

It should be quoted here that de Castro, together with B. Lawrentjew, was among the first scientists specifically studying regeneration of synaptic contacts in the sympathetic system Lawrentjew, , a , b ; de Castro, In this series of scientific articles, de Castro showed in detail the cytoarchitecture of sympathetic and parasympathetic autonomic motor ganglia in humans, in other primates and in several large mammals.

At that time the exhaustive and expert works of Fernando de Castro in the field of the histology of somatic sensory and autonomic ganglia had gained international recognition. The most clear example of this came by hand of the famous American neurosurgeon and neuropathologist Wilder S. Sympathetic neurons by Fernando de Castro.

This image was published in de Castro B Partial view of a sympathetic ganglion normal condition of an adult cow de Castro, C Portion of a sympathetic ganglion with regenerated preganglionic fibers a after a vagus-sympathetic crossed anastomosis de Castro, ; A is part of Archive Fernando de Castro.

But at that moment, a young fellow, Fernando de Castro, came in. Cajal left us then and I did stay on to talk with de Castro.

The painter came to Spain because he wanted to visit exiled last Austro-Hungarian empress, Zita, exiled in Spain. Following recommendations of his brother Deszo, he visited Fernando de Castro at Madrid, who showed him his scientific drawings and his deep interest and knowledge in Art.

The painter gifted this charbon portrait to the Spanish neuroscientist as a proof of the close frienship of both Miskolzy brothers and Fernando de Castro.

Unfortunately, there was no extra time to work with de Castro. Hortega had spread off. The most recent discoveries came from him and his research was still far from completed. This could be considered as his first interest in the synapse.

In the attempts to prove his hypothesis that neurons located in the carotid bodies act as sensory chemoreceptors that detect changes in the chemical composition of circulating blood, Fernando de Castro took an alembicated experimental way that should pass through… the orthosympathetic ganglia! These postdoctoral fellowships had the potential to be very successful for Fernando de Castro.

The direct and indirect results of the experiments undertaken in the Italian collaboration became incorporated in work published in the immediate years after de Castro had returned to Madrid de Castro, , Civil war erupted in Spain in and fighting reached Madrid towards the end of that year.

In the mean time the Belgian physio-pharmacologist Corneille Heymans — took advantage of the opportunity and won the race to functionally demonstrate the origin in the carotid body of the chemical reflexes.

Heymans consequently was awarded in with the Nobel Prize in Physiology or Medicine. The study of structure and function of synapses had significantly progressed in these years already, and de Castro assumed that the study of synapses in the autonomic nervous system would really be profiting since the structure of the ganglia is simpler than that of the CNS and his particular knowledge on the fine structure of the sympathetic ganglia would undoubtedly be of great help in this new research Figures 5A,B.

Post-war de Castro on the autonomic nervous system and their synaptic structure. A Electromiographic recordings of the nictitant membrane of the adult cat where the sympathetic superior cervical ganglion has been innervated by rami from the VI-c and VII-c nerves de Castro and Herreros, This 10 s-recording shows that the intensity of the contraction correlates with the frequency of the tetanic stimulation.

B Schematic representation of the preganglionic convergence of fibers a, b, c onto ganglionic cell types A, B, C. The thickness of the fibers is representative of their thickness in vivo. In this it is assumed that ganglion cells can trigger when activated by two boutons simultaneously, or in the slow fibers c when a sinchronic impulse via a-b facilitates it de Castro and Herreros, Gallego will come with you to New York and will bring you to your accomodation, that is worthy and economic.
