Anti Alzheimer helmet

Wanted: slightly demented tansgenic APP mouse with giant head to serve as guinea pig for career in helmet industry.
What You get: A tanned brain against Alzheimer: what else....
PS Important notive: do not forget to turn the fans on or Your brain might start cooking (if You hear boiling noises and feel some blubber coming out of Your nose and ears it might be to late).
If so watch for the chicken legged elephant gray nano suit against boiled brains to be announced real soon . Next week in a clinic not far away ....

Rythms of The Brain

Gyorgi Buzsaki's masterpiece:
a must have for every serious brainscience afficionado
Editorial Reviews Review"Gyorgy Buzsaki's Rhythms of the Brain is an excellent compendium on the rapidly expanding research into the mechanisms and functions of neuronal synchronization. Buzsaki presents such synchronization as a binding glue that integrates many levels of neuroscientific investigation with one another and with neighboring disciplines...Buzsaki manages to elegantly integrate insights from physics, engineering, and cognitive psychology with contributions from cellular, systems, cognitive, and theoretical neuroscience."--Science"This is definitely an intriguing book that provides a comprehensive review of current knowledge on brain rhythms...this book is worth the time."--Doody's"For the non-scientist reader, a really good science book is almost never about science as much as it is about the scientist...But then comes along a book by a literature, engaging scientist. This author, you quickly realize, is willing to take a complex topic and explain, with patience, humility and a modicum of humor as the effort progresses, (1) why he or she thinks one way and not another, (2) discuss with honesty and integrity what is known about the subject and what isn't close to being confirmed and (3) detail candidly the dirty little secrets of the experimental laboratories and the secret little condescensions and the subtle omissions of the experimenters...As it turns out, the rhythms of Dr. Buzsakis mind have produced a fascinating read that a scientifically curious non-scientist can follow if they are willing to make the effort." --BrainTechnologies"In Rhythms of the Brain, Gyorgy Buzsaki does a remarkable job of summarizing a vast body of literature on the topic...The book is a 'must read' for anyone interested in understanding the functioning of large and complex brain circuits."--Nature"What makes this book so valuable is its range; Buzsaki has a worldly intellect, open to information from any discipline that provides insight, while insisting on a rigorous distinction between fact and baloney...Perhaps the greatest value of Rhythms of the Brain is that it provides a starting point for students and scientists who see the importance of this field and want to get a solid overview."--Nature Neuroscience"In this entertaining monograph the author addresses issues related to the genesis of brain rhythms and their contribution to the "invisible operations of the brain"...one of the most thought-provoking and fun books in neuroscience that I have read in some time."--Mathematical Reviews"Highly original exposition of a broad swathe of modern neuroscience. Indeed, it brings together so many apparently disparate strands, and levels on the reductionistic scale, that it deserves a must read score, especially for neuroscientists looking to get an up-to-date and challenging exposition of many of the big questions, even if they are not fundamentally interested in oscillations per se...If sharp wave ripples, associated with consummatory behavior in rodents, have the same connotations in humans, they too will likely occur in the readers brain as a reward for the attention this book deserves."--Neuron"The book is beautifully written...This book is seriously recommended for those who truly wonder about the brain and its function."--Neuroscience Book DescriptionStudies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the co-evolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brains fundamental organizer of neuronal information. The small world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive metastable state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of cycles, Gyorgy Buzsaki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing accessible to any reader with some scientific knowledge is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.

Signal processing for Neuroscientists

The hichhikers guide to the EEG galaxy
Signal Processing for Neuroscientists: An Introduction to the Analysis of Physiological Signals by Wim van Drongelen (Author) Signal Processing for Neuroscientists introduces analysis techniques primarily aimed at neuroscientists and biomedical engineering students with a reasonable but modest background in mathematics, physics, and computer programming. The focus of this text is on what can be considered the golden trio in the signal processing field: averaging, Fourier analysis, and filtering. Techniques such as convolution, correlation, coherence, and wavelet analysis are considered in the context of time and frequency domain analysis. The whole spectrum of signal analysis is covered, ranging from data acquisition to data processing; and from the mathematical background of the analysis to the practical application of processing algorithms. Overall, the approach to the mathematics is informal with a focus on basic understanding of the methods and their interrelationships rather than detailed proofs or derivations. One of the principle goals is to provide the reader with the background required to understand the principles of commercially available analyses software, and to allow him/her to construct his/her own analysis tools in an environment such as MATLAB. Hardcover: 320 pages Academic Press; 1 Har/Cdr edition (December 13, 2006) Language: English ISBN-10: 0123708672 ISBN-13: 978-0123708670

Alienware

Take the ultimate driving simulator (STISIM) and combine it with the ultimate screen from Alienware (to be relased sec half 2008) and You are in for a new dimension in virtual driving simulation. It can be used for gaming but also for serious research (combine with EEG) and clinical testing of driver abilities.

The invisible man (or woman)

THIS IS WRITTEN IN INVISIBLE INK (unless my photons have taken the wrong tunnel again)
Of course there are moments in life that invisibility would "suit" us all or that a carpet for cloacking as Harry Potter was using , would be a most welcome asset. Fact or fantasy. Well some work has already been done. Read about it in the latest jan issue of Nature and you will understand my motto "all I know I learned from Star Trek".

AMAZING EXPERIENCE
What is a reactable and what is the picture of such a strange device doing on this blog ? Well we tend to forget that the brain is a multisensory integration organ and sometimes that can go off track as in shizophrenia (cfr studies of John Foxe). You can listen to music but maybe it is a much more interesting idea to simultaneously look at it (taste it ?? ), even touch it , feel it, use it, manipulate its components and see , hear and feel the real time effects interactively and immediately. That is what i call "playing" music. That is also what these wonderfully intelligent and creative wizzards of the Pompeu Fabra University of Barcelona have managed to do very succesfully. It's is not only nice as a musical experience but for signal analysis buffs it lets You interactively experience, see and feel the effects of filters, sound generators, output filters , waveforms and later perhaps FFT displays ... links toBCI pop in mind. The components are 3D manipulative bbuilding blocks. It's like 3D mathlab simulink adding the spatial dimension. Experience part of it at Youtube. Seeing is better then reading.... Kudo's to these guys in Barcelona and thanks very specifically for mentioning this discovery link to me, to my wonderfull Mexican friend , super mario : Mr Jose Pablo dela Torre, former exchange student and now a manager of a very interesting Mexican rock band called DRAWN. Rock fans click here.. Thanks José !!
