Prof. B. Chandra and the Dragonfly
Gathering of Neurology Alumni 2017 UNAIR
Do you know what happens to our brains in the first weeks of life in the womb? The central nervous system, in fact, consists of only three tubular formations, which then evolves into five tubular formations resembling a dragonfly. Early before the blood vessels are formed, nutrients are filled only by the diffusion of the amniotic fluid. Thus, when a similar formation of the tube continues to expand, the diffusion is no longer able to supply nutritional needs. Due to increased metabolic requirements, the process of vasculogenesis and angiogenesis begin. Do you know that the cortical blood vessels of the oldest kind are the anterior cerebral artery (ACA)? Together with the anterior choroidal artery (which is very prominent at that stage), it meets the needs of “The Dragonfly” in order to continue to grow larger. The Dragonflies have 5 segments called 1) Telencephalon, 2) Diencephalon, 3) Mesencephalon, 4) Metencephalon (Pons), and 5) Myelencephalon. We know that the Dragonflies get the blood flow from just one vascular system, namely the primitive common carotid artery (PCCA). At that point, there are no terms such as basilar artery and vertebral artery. PCCA is able to meet the needs of the five tubes. There is also no anterior circulation (carotid system) and posterior circulation (vertebrobasilar system). There is only one circulation from PCCA. Afterwards, the middle cerebral artery (MCA), which is currently well known because of its size and vital role, is initially only a small branch of the ACA. Anterior choroidal artery, which initially played a very large role, begins to withdraw and allows MCA to develop with many branches to meet the needs of the cerebral, becoming the new favorite of cerebral vascularization. Did you know? After that, PCCA begins to withdraw its role. The last two tubes have developed, and the posterior circulating blood vessels have been formed. Next, the vertebral artery and basilar artery appear. PCCA becomes the anterior circulation (carotid system), but its services in maintaining the posterior system are still visible. It does not separate at all and there is still a small vein formed by the remaining posterior communicating artery (P.com). PCCA is the mother. If the posterior blood flow is disrupted, the mother through P.com will be ready to provide assistance by providing supply to the posterior circulation.
So what is the relation between the above explanation and Prof. Benjamin Chandra, dr. Sp.S (K), Sp.KJ, Ph.D? Prof. Chandra may not be well known to the later generation of neurologists. The young doctors of FK (Faculty of Medicine) UNAIR in the 2000s were fortunate to meet him once a week. His Clinical Neurology book was used as a reference and brought wherever the young doctors and residents went since the Internet access and ebook were not as ubiquitous as today. Prof. Chandra replaced Prof. Soejonoes, who was the founder of neuropsychiatry UNAIR, and then became the Head of Department and built the foundation of neurology in Surabaya. After that, the Department of Neurosurgery and Medical Rehabilitation was developed which is related to neurology. Prof. Chandra is very prominent because of his works. He was the scientist who opened neurology studies in Surabaya. Currently, neurology studies in Surabaya are growing rapidly. Prof Chandra also taught neurology studies at UNS Solo, University of Udayana Bali, and University of Brawijaya Malang. Now, the three universities have been able to work remarkably and independently on neurology.
Thus, these forerunners are the initiators of our existence as neurologists. For that reason, a tribute to Prof. Chandra entitled “Prof. Chandra and the Journey of Neurology Surabaya,” was taken as the theme of the UNAIR Neurologist Alumni Meeting. The alumni gathering coincided with the activity of “The 18th CNE (Continuing Neurological Education) Surabaya,” on May 5-7, 2017. A historical flashback film was played in the event and the seniors gave their testimonies about the important role of Prof Chandra. The Alumni Meeting was held at the Mercure Hotel, on May 6, 2017 (7:00 pm to 9:00 pm). The committee invited the UNAIR Neurology Alumni associates to participate in the Alumni and CNE Surabaya gathering. The topic of CNE Surabaya 2017 was “The New Era: Towards Curative Neurology”.
