Ll themselves all the time for the good of the system the animal body For xample 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 provided xamples of apoptosis in the human animal she wrote about the actual process of apoptosis 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 Crown of Stars (Crown of Stars, examples including somme little known trivia about Monet Thank you Frances Ashcroft for writing a book that makes me feel like I was luckynough 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 the nergetics of animal systems and not to have to do problem sets or take xams The only thing that would make me happier would be for Ashcroft to put her lectures in a public domain so I could watch very last one of them A scientist talking about lectricity in the human body ties into This Forsaken Earth energy therapy design in nature and the dots are starting to join up but I m only on p58 The Spark of Life is a fascinating tour of thelectrochemical system in the human body Starting with the discovery of The Summer Palace: A Captive Prince Short Story (Captive Prince Short Stories Book 2) electricity and the subseuentvolution in the understanding of the role of The Garden of Happy Endings electricity in the body Ashcroft cogentlyxplains in relatively deep technical detail the many aspects of the human Campfire electrical 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 acetylcholinetc There s also a good My Little Blue Dress explanation 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 anxtended period of time After it reopened and I was able to check it out again I remembered how much I Hurrah For The Blackshirts!: Fascists and Fascism in Britain Between the Wars enjoyed 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 chaptersspecially in the second half come across as collections of somewhat related bits of information about Adam Smith: An Enlightened Life electricity 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 Rating 4 of 5Okay so I think I ll have to read The Spark of Life Electricity in the Human Body at least three or four times to fully understandverything Ashcroft covered It was fascinating to learn the history of Crazy Love electricity and I couldn t getnough of Chapter 9 The Doors of Perception Even for non scientists like moi there is much to learn from The Spark of Life despite its scientific terminology and Annual Editions: Technologies, Social Media, and Society explanations What I loved most about the book was how much it made is making me think and wonderThe freakiest part of the whole book was pages 309 311 when Ashcroft shared her desire for a intimate connection between the brain and a computer To paraphrase she d like the ability to physically connect her brain to a computer in order to instantly access memories and important information She admits this is currently only science fiction But science fiction often has a way of becoming science fact Anyone see thispisode of X Files I ll pass

This was not a fast read but uite understandable to the ducated 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 causing lectrical currents throughout the neurons causing muscles to contract and glands to secrete or not The history of the discovery of ЯED electricity 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 problem Do you thirst for in depthxplanations about how your body works If so read this book We know well how an lectric 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 xample she does an amazing job of Moreno explaining how the inside of the cell has a high potassium concentration while the outside of the cell has high sodium concentration This creates a gradient that allows the current of biolectricity to continually flow through the body Having done such a great job simplifying that for the reader Ashcroft was perfectly positioned to Monsieur Pain explain how that current is turned into axon potentials which governvery process in which humans A Spark of Light: the fearless new novel from the Number One bestselling author engage 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 werextremely satisfying for me but not as relatable as Ashcroft s writing I have to say I felt What If entirely perplexed that Ashcroft believes that life probably began in a tiny little pond I have no idea how she can believe this It sntirely 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 The Exhaustion Breakthrough 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 The Exhaustion Breakthrough: Unmask the Hidden Reasons You're Tired and Beat Fatigue for Good 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 Supplemental Book 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 Hark!
