In her most catchily titled book, The Angel and the Assassin , Donna Jackson Nakazawa highlighed nerve cells which have hitherto been very little acknowledged – microglia . Long ignored as bit players in the big league of the nervous system, Nakazawa colourfully illustrated what many neuroscientists are beginning to realise: the small size of microglia belies their huge influence ; m icroglia are, after all, the defence force of the nervous system, protecting the brain from microbial invaders . In keeping with their small size, their role is to surreptitiously  present the antigens of invading bugs to T cells , the toffs who actually carry out the final hatchet job . It is therefore not surprising that any dysfunction of microglia will come with significant clinical consequences .  By GerryShaw – Own work , CC BY-SA 3.0 , Link The most important clinical fallout of dysfunctional microglia appears to be the emergence of dementia. It is indeed speculated that mi

These topics, in turn, are grouped […] What are the 695 topics that make up neurology? — Neurochecklists Blog from The Neurology Lounge https://ift.tt/3kWDJBi

A critical part of history taking in medicine is establishing the occupation of the patient. This is because occupational activities and work place exposures are often major contributors to the disease. Furthermore, at the end of the medical process, the eventual diagnosis may have an impact on the patient’s ability to return to work . To be relevant, the occupational history must be exhaustive   – it must establish current and past occupations, the tasks carried out, the risk of toxic exposure , and the use of personal protective equipment (PPE) . The occupational history is so important to neurology that a whole subspecialty, occupational neuroscience , has emerged to evaluate “the effects of complex environmental and occupational exposure on working people”.

It is difficult to really say when neuroscience began, but most sources trace the first account of the nervous system to what is now known as the Edwin Smith papyrus ; this is an Egyptian text written around 1700 B.C which documents surgical procedures for brain trauma. Since then, neuroscience breakthroughs  have come at breakneck speed. The sources I have consulted for this blog post, referenced at the end, name innumerable discoveries made by countless innovators . To attempt to put a number to the most important breakthroughs will therefore be a well-nigh impossible task. So I came up with the idea of chunking key discoveries under distinct sections or systems of the nervous system. By Jeff Dahl – Edited version of Image:EdSmPaPlateVIandVIIPrintsx.jpg , Public Domain, Link But even this plan to chunk key breakthroughs came with strong challenges . For example, it is not always clear  when a discovery was first made, or who crossed the finishing line first. This is bec
