educated layperson I learned a great deal from the AC or DC wars of Edison and Tesla to the ways ion channels which are proteins control whether and when certain ions pass into or out of the cells causinglectrical currents throughout the neurons causing muscles to contract and glands to secrete or not The history of the discovery of lectricity was great and the means by which it has been used for good or ill to treat many different maladies was a very interesting aspect of the bookThe fact that the ion channels can be deformed due to genetic mutations causing lifelong serious illness was fascinating as well as the possibility of finding ways to treat these problemsThe functions of the sense organs and various receptors including those for taste and pain were lucidated I found a plausible Codependent Forevermore: The Invention of Self in a Twelve Step Group explanation of why some people are sensitive to pain than others reuiring pain medication forxample a subject I often wondered about It s all about Nav17 sodium channels A common genetic variant in these protein channels can determine a pain thresholdI think I would like to own this book I got it from the library because there is so much information that will be hard to remember I would like to refer to it oftenMaybe I will get a copy for Christmas.

This book is life altering and paradigm changing If you ve not been amazed by your own body just yet firstshame on you and second buy this book and keep it as a national treasure The overall content of the book is about how lectricity is generated in our amazing bodies All of our thousands of cells contain potassium and outside of the cell is highly concentrated with sodium Within all of our cells we have these amazing things called ion channels that are innervated by a multitude of things and they open and close letting sodium in and potassium out This very act of Conscience and Memory exchanging within the protein of the ion channels is the very thing that innervates us We literally are the bodylectric We re amazing These ion channels are literally responsible for Pansy Vol. 6 everything If you have a defective ion channel you could have an ailment that you already know about but little did you know that the ailment is due to ion channels Everything our senses our brains ourmotions personality behavior all boils down to ion channels It literally moves me to tears I highly recommend this book When I get accepted into the PhD program I want guess what my dissertation will be on D Since I m in the middle of my female authors only month I thought now would be a good time to get round to some of the non fiction books I have by women specially in the STEM field I d forgotten I had this one which is a shame it fits into my general theme of reading about neurology and builds on a lot of the stuff about ion channels that I learnt in an introductory biology class on Coursera I understood pretty much all the science without wanting or needing to look anything up or letting anything wash over my head in part that s because Ashcroft writes very accessibly but I think it is also because this is stuff I know and loveSome of it is a little too much towards the neurology nd of things for me I wanted about Elizabeth I electricity in the human body of the sparks and less of the chemical messages the soups in that old scientific debate this veered towards talking much about the chemical parts of the processspecially toward the Education in a New Society end On the other hand it s the chemical processes that create thelectrical potentials and make all of the Education in a New Society: Renewing the Sociology of Education electricity in the human body and other animals too possible so it s uite inextricable It just felt like it wanderedCalling the book The Spark of Life is a little misleading perhaps It talks aboutlectricity in the body yeah but that s too small a part of the process to be considered alone and a lot of other factors have to be discussed at uite some length Ashcroft uses good xamples and xplains things clearly there s a section of notes in the back for those who want to get a little Deeper Into ItOriginally Posted Here A Well into itOriginally posted here A well and balanced book that gets neither too complex or patronising delivering the technical facts at a rate they can be absorbed by the layperson interspersed with a level of anecdotes that keep it flowing at an agreeable rate without with a level of anecdotes that keep it flowing at an agreeable rate without becoming a tome of personal triumph or vehicle for misplaced humour as is often the case with less diligent science authors The Spark of Life is a fascinating tour of the The Baby Swap Miracle electrochemical system in the human body Starting with the discovery oflectricity and the subseuent volution in the understanding of the role of lectricity in the body Ashcroft cogently xplains in relatively deep technical detail the many aspects of the human lectrical system I had not known about the many different ways that tetrodotoxin the toxin in fugu curare sarin and other toxins do their damage whether blocking shut ion channels blocking open ion channels preventing the breakdown of acetylcholine tc There s also a good xplanation and funny picture of myotonic fainting goatsI read about 23 of this book before having to return it to my local library because it was closing for renovations for an Excommunication: Three Inquiries in Media and Mediation extended period of time After it reopened and I was able to check it out again I remembered how much Injoyed the book and I started over from the first page I virtually never read a book twice so that it is a very positive complimentMy biggest criticism of the book is that some chapters Gender Justice especially in the second half come across as collections of somewhat related bits of information aboutlectricity in the human body Now this info was still fascinating but it felt at times like reading from Wikipedia pages But very well written ones do you thirst for well written ones Do you thirst for depth Generations and Collective Memory explanations about how your body works If so read this book We know well how anlectric cord works when plugged into an outlet and a switch is flipped But what plugs you in What sort of current does the human body use to breathe at move have sex read a book or ven to sit and think Ashcroft goes into great detail about the currents that make you an active system Instead of an outlet in a wall the currents inside humans and other animals are generated by tiny ions that flow through ion channels This is the thermodynamics of life at its best Though she never actually mentions thermodynamics Ashcroft included all the best concepts learned in classes such as intro to neuroscience intermediate biochen and the lighter aspects of neurocellular biochem and neurophysics For From Notes to Narrative example she does an amazing job ofxplaining how the inside of the cell has a high potassium concen. What happens during a heart attack Can someone really die of fright What is death anyway How does Guitar Makers: The Endurance of Artisanal Values in North America electroshock treatment affect the brain What is consciousness The answers to these uestions lie in thelectrical signals constantly traveling through our bodies driving our thoughts our movements and ven the beating of Tration while the outside of the cell has high sodium concentration This creates a gradient that allows the current of bio lectricity to continually flow through the body Having done such a great job simplifying that for the reader Ashcroft was perfectly positioned to Hard Bread (Phoenix Poets (Paper)) explain how that current is turned into axon potentials which governvery process in which humans ngage She really brought the magic of cells and ion channels alive Energy flow in the human body and in all cells is one of my favorite topics to read about and think about It s hard to find a book this detailed Some authors choose this subject to write about but their numbers are surprisingly few Nick Lane s Life ascending and Power Sex and Suicide were xtremely satisfying for me but not as relatable as Ashcroft s writing I have to say I felt ntirely perplexed that Ashcroft believes that life probably began in a tiny little pond I have no idea how she can believe this It s ntirely possible Nick Lane along with Martin and Russell are wrong in their hypothesis that life originated at the hydrothermal vents But if life did not originate there it seems necessary not just likely that it arose somewhere that provided the Foraging for Survival energy needed to create and maintainnzymes that make cellular products This aspect of the book will bother me continuously until I understand how she can account for the needed Fragments energy of thenzymes She is far knowledgeable than I am as is Nick Lane So I am sure there is something I missing about her hypothesis But it s driving me crazy and she did not write about where the Foundations of Tropical Forest Biology: Classic Papers with Commentaries energy would have come from in her scenarioFrom page one I fell in love with this book It was uickly clear that this was the biochem ion channel book I have been looking for all my life I remember learning about how our brain cells work to help us see smell taste hear see and touch our world My mind was completely blown away because I simply could not believe nature could be that beautiful and that brilliant But it is and Ashcroft did a great job of conveying how much of that brilliance is due to ion channels Ashcroft herself states that This is a book about ion channels Indeed it is For it is the ion channel that takesvery xperience you will ver have with the world around you and detects transmits and processes very last bit of it so that you can ven call it an xperience It was clear to me that Ashcroft is in awe of the body which has as many cells as the galaxy has stars and the brains inside those bodies She wrote about action potentials resting potentials on ach side of the membrane and why that matters and how that makes you able to function and live in the world Despite having read so much similar material for years Ashcroft made my dopamine neurons go crazy during One Ticket To Texas each page because shexplains it all so tremendously well I would have been happy with a book 4 times as long Her coverage of cell suicide was crazy good so good in fact I kept saying How can this book Helpmate evenxist I really love cells Cells kill themselves all the time for the good of the system the animal body For Art, Culture, and Cuisine: Ancient and Medieval Gastronomy example if cells did not undergo apoptosis during our fetal development we would all have webbed fingers and toes If cells didn t undergo apoptosis after we were born our brains simply could not function After she providedxamples of apoptosis in the human animal she wrote about the

actual process of 
process of in which the cell takes over the mitochondria and directs it to kill itself so goodShe gave a beautiful description of photosynthesis but it is likely not what you have heard before Yes she covers the basics but she tells the story of photosynthesis from the perspective of the ion channel The last part of the book discussed what happens when ion channels work or do not work correctly The result is a sensual xperience of the world or an inability to sense the world This section came alive with great xamples including somme little known trivia about Monet Thank you Frances Ashcroft for writing a book that makes me feel like I was lucky Black British Cultural Studies: A Reader enough to hop on a plane fly over to England take a seat in your lecture hall at Oxford University and learn the intricate details about thenergetics of animal systems and not to have to do problem sets or take Gypsy World: The Silence of the Living and the Voices of the Dead exams The only thing that would make me happier would be for Ashcroft to put her lectures in a public domain so I could watchvery last one of them I think most of us are aware that the human body uses both chemical and Bryozoan Evolution electrical signalling to control its inner functions but until I read this book I had certainly never realised thatxtent to which a rather strange Crisis and Continuity at the Abbasid Court: Formal and Informal Politics in the Caliphate of Al-Muqtadir (295-320/908-32) electrical process strange because it involves the flow not oflectrons as in normal Silvers Edge electricity but of ions is handled by ion channelsAfter a preface that is a little confusing as she uses terms that aren t reallyxplained until later biologist Frances Ashcroft who spends her days working with ion channels gives us a brief introduction to lectricity this physics part is by far the weakest physics part is by far the weakest of the book For xample she doesn t differentiate between a flow of Going Berserk electrons and thelectromagnetic signal in a wire and some of the history is a little out of date she says for instance that Franklin did the kite in a thunderstorm xperiment which is thought unlikely now But this is only an in.
