Review ✓ Connectome ´ E-book, or Kindle E-pub Ectome as it’s called is where our genetic inheritance intersects with our life experience It’s where nature meets nurtureSeung introduces us to the dedicated researchers who are mapping the brain’s connections neuron by neuron synapse by synapse It is a monumental undertaking the scientific euivalent of climbing Mount Everest but if they succeed it could reveal the basis of personality intelligence memory and perhaps even mental disorders Many scientists speculate that people with anorexia autism and schizophrenia are wired differently but. Who are we What are we Dualists take the position that the mind is separate from the brain while monists say they are the same thing The connectome presents an intriguing third option the mind is not the brain per se but rather the way that the neurons are connected Sebastian Seung presents this using everyday language relating the effects to everyday occurrences and meaning Your genes determine how your body grows from an egg to an adult Your connectome is determined only partially by your genes and uite a bit larger part by your experiences It is almost a platitude your experiences make you what you are but in this book we have a clear explanation of why and how that worksPart I starts by looking at the history of brain science Phrenology the study of the shape of the skull is a largely discredited pseudoscience but Seung teases us with the idea that phrenology at least promoted the idea that certain kinds of mental processing is associated with certain parts of the brain Brain size has always been a historical fascination but it is the structure that is important not the size Penfield s sensory homunculus maps specific sensory functions to specific parts of the brain Phantom senses from amputated limbs can be found in this mappingPart II starts with the building blocks neurons how they function how they grow and most importantly how they connect Seung s unconventional style leads us to the Jennifer Aniston neuron which apparently we all have It is a specific neuron that is triggered when we recognize Jennifer Aniston Similar neurons exist for all other specific concepts that we have come to know This brings him to an explanation of how memory works Neurons are triggered or inhibited through their connections The repeated firing of neurons at the same time cause neurons to create new synapses new connections that are the basis for long term memory Learning is then simply the making of new connections between neurons The way we perceive the world and the way we remember what happened to us in the past all comes from the pattern of connections between the neurons The future of psychiatry is destined to be reduced to a new field called connectopathy the ways that the connectome might be mis wiredHowever connections are not simply binary on off mechanisms The connectome in changed through four different mechanisms which he calls the four R s of connectome change reweighting reconnection rewiring and regenerationPart IV shifts to practical matters how can we measure and study the connectome He surveys the various means for solidifying the brain slicing it photographing recognizing the structures and tracing the path of nerves and how they are connected For a worm with 302 neurons this has been done but this is hardly a practical approach for humans scale brains MRI and other techniues allow studying living brains It is all a bit too course grained for now because while understanding the function of regions of the brain is important it is the actual specific connections between specific neurons that form actual intelligence Technology allow for increasingly fine observations and increasingly massive data result sets and it would appear that some day it may be possible to map your connectome Part V concludes the book with some interesting speculation that is sure to please the science fiction fans among us can we achieve immortality through scientific means First can we freeze or pickle ourselves and be revived in the far future when death has been cured Second can we be uploaded to a software simulation of the brain If the connectome can be fully traced in an individual there is no reason that a simulation of the nerves would not produce a running facsimile of that individual with all their memories and skills However that copy of the person would be that a copy and not the original individual It would make no sense to desire that a copy of ourselves achieves immortality however some connectomes are wired to be insanely egocentric and just might decide to do it anywayOne tidy book brings us up to date on the state of neurology at least at a level that can be understood without a background in neurology The book has to dispel a lot of myths and historical pseudoscience It also makes it clear that we are still just at the beginning of the journey of understanding how the connectome achieves its most baffling result a sense of consciousness
