Time Spike by Eric Flint,Marilyn Kosmatka Pdf

THE DEADLIEST PREDATORS OF THREE SEPARATE EONS Captain Andy Blacklock was overseeing the change of shifts at the state of Illinois' maximum-security prison when the world outside was suddenly ripped. They thought it was an earthquake until they found that the Mississippi River had disappeared, along with all signs of civilization. Then the sun came up¾in the wrong direction. And a dinosaur came by and scratched its hide against the wall of the prison ... Something had thrown the prison back in time millions of years. And they were not alone. Other humans from periods centuries, even millennia, apart had also been dropped into the same time. Including a band of murderous conquistadores. But the prison had its own large population of murderers. They couldn't be turned loose, but what else could be done with them. Death walked outside the walls, human savagery was planning to break loose inside, and Stephens and the other men and women of the prison's staff were trapped in the middle.

Analysis of Parallel Spike Trains by Sonja Grün,Stefan Rotter Pdf

Solid and transparent data analysis is the most important basis for reliable interpretation of experiments. The technique of parallel spike train recordings using multi-electrode arrangements has been available for many decades now, but only recently gained wide popularity among electro physiologists. Many traditional analysis methods are based on firing rates obtained by trial-averaging, and some of the assumptions for such procedures to work can be ignored without serious consequences. The situation is different for correlation analysis, the result of which may be considerably distorted if certain critical assumptions are violated. The focus of this book is on concepts and methods of correlation analysis (synchrony, patterns, rate covariance), combined with a solid introduction into approaches for single spike trains, which represent the basis of correlations analysis. The book also emphasizes pitfalls and potential wrong interpretations of data due to violations of critical assumptions.

Spike Timing by Patricia M. DiLorenzo,Jonathan D. Victor Pdf

Neuronal communication forms the basis for all behavior, from the smallest movement to our grandest thought processes. Among the many mechanisms that support these functions, spike timing is among the most powerful and—until recently—perhaps the least studied. In the last two decades, however, the study of spike timing has exploded. The heightened interest is due to several factors. These include the development of physiological tools for measuring the activity of neural ensembles and analytical tools for assessing and characterizing spike timing. These advances are coupled with a growing appreciation of spike timing’s theoretical importance for the design principles of the brain. Spike Timing: Mechanisms and Function examines the function of spike timing in sensory, motor, and integrative processes, providing readers with a broad perspective on how spike timing is produced and used by the nervous system. It brings together the work and ideas of leaders in the field to address current thinking as well as future possibilities. The first section of the book describes the foundation for quantitative analysis and theory. It examines the information contained in spike timing, how it can be quantified, and how neural systems can extract it. The second section explores how input-output relationships are reflected in spike timing across a range of sensory systems. Drawing together multiple perspectives, including theoretical and computational studies as well as experimental studies in a range of model systems, the book provides a firm background for investigators to consider spike timing as it applies to their own work. It also offers a glimpse of future advances related to mechanisms of spike timing and its role in neural function, such as the development of novel computational technologies.

Spike-timing dependent plasticity by Henry Markram,Wulfram Gerstner,Per Jesper Sjöström Pdf

Hebb's postulate provided a crucial framework to understand synaptic alterations underlying learning and memory. Hebb's theory proposed that neurons that fire together, also wire together, which provided the logical framework for the strengthening of synapses. Weakening of synapses was however addressed by "not being strengthened", and it was only later that the active decrease of synaptic strength was introduced through the discovery of long-term depression caused by low frequency stimulation of the presynaptic neuron. In 1994, it was found that the precise relative timing of pre and postynaptic spikes determined not only the magnitude, but also the direction of synaptic alterations when two neurons are active together. Neurons that fire together may therefore not necessarily wire together if the precise timing of the spikes involved are not tighly correlated. In the subsequent 15 years, Spike Timing Dependent Plasticity (STDP) has been found in multiple brain brain regions and in many different species. The size and shape of the time windows in which positive and negative changes can be made vary for different brain regions, but the core principle of spike timing dependent changes remain. A large number of theoretical studies have also been conducted during this period that explore the computational function of this driving principle and STDP algorithms have become the main learning algorithm when modeling neural networks. This Research Topic will bring together all the key experimental and theoretical research on STDP.

Mathematical Derivation of the Interspike Interval Histogram from the Spike Occurrence Histogram of Neuronal Spike Data by Marvin C. Ziskin Pdf

In the analysis of neruronal spike data, the spike occurrence histogram and the interspike interval histogram are frequently computed. Both of these computations are derived independently from the raw data. In a previous report, it was shown that under certain conditions, the interspike interval histogram can be derived directly from the spike occurrence histogram. The report provides the complete mathematical details of this derivation. The predictive ability of the derived equation is demonstrated using computer-simulated data and with actual neurophysiological data. In all of these cases, the agreement between the predicted and empirical results satisfied chi-square goodness-of-fit criteria at the 95% confidence level. (Author)

The Spike by Mark Humphries Pdf

The story of a neural impulse and what it reveals about how our brains work We see the last cookie in the box and think, can I take that? We reach a hand out. In the 2.1 seconds that this impulse travels through our brain, billions of neurons communicate with one another, sending blips of voltage through our sensory and motor regions. Neuroscientists call these blips “spikes.” Spikes enable us to do everything: talk, eat, run, see, plan, and decide. In The Spike, Mark Humphries takes readers on the epic journey of a spike through a single, brief reaction. In vivid language, Humphries tells the story of what happens in our brain, what we know about spikes, and what we still have left to understand about them. Drawing on decades of research in neuroscience, Humphries explores how spikes are born, how they are transmitted, and how they lead us to action. He dives into previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? Humphries presents a new vision of the brain, one where fundamental computations are carried out by spontaneous spikes that predict what will happen in the world, helping us to perceive, decide, and react quickly enough for our survival. Traversing neuroscience’s expansive terrain, The Spike follows a single electrical response to illuminate how our extraordinary brains work.

Spike your Brand ROI by Adele R. Cehrs Pdf

Increase ROI through more effective brand marketing According to CMO.com, we are exposed to more than 5,000 brand messages each day. Marketers call this “creating engagement," and each comment, share, or re-tweet is supposed to be a win. But is this deluge of content really working to shift perception, change behavior, or sell products? The truth is, only 5% of people say that social media has a profound effect on their purchasing decisions. Moreover, only 2.7% of people are willing to stick their neck out on the line to recommend your brand via social media, a factor known as “social risk.” In SPIKE Your Brand ROI, public relations maven Adele Cehrs shares her strategy for effective engagement: it’s all about timing. This book will teach you how to recognize, anticipate, or even create a SPIKE – a Sudden Point of Interest that Kick-starts Exposure. This is your opportunity to reach people when they are primed to hear your message, and your brand is most relevant to their lives. Based on the author′s actual engagements with clients like Yum Brands, Lockheed Martin, DuPont, and more, this practical guide outlines a new, pragmatic approach that will enable you to: Learn to recognize brand patterns that are driven by audience interests and outside events Focus your energy, resources, and money when your brand is top-of-mind Decrease your marketing spend while increasing your bottom-line benefits Maximize benefits or mitigate damage by anticipating when your company, association, or nonprofit is going to be in the spotlight Retool traditional word-of-mouth initiatives for optimum results With Adele Cehrs' proven methodology, you can turn a SPIKE into a strategic platform from which to improve results, build respect, and boost your ROI.

The Last Spike by Pierre Berton Pdf

In the four years between 1881 and 1885, Canada was forged into one nation by the building of the Canadian Pacific Railway. The Last Spike reconstructs the incredible story of how some 2,000 miles of steel crossed the continent in just five years — exactly half the time stipulated in the contract. Pierre Berton recreates the adventures that were part of this vast undertaking: the railway on the brink of bankruptcy, with one hour between it and ruin; the extraordinary land boom of Winnipeg in 1881–1882; and the epic tale of how William Van Horne rushed 3,000 soldiers over a half-finished railway to quell the Riel Rebellion. Dominating the whole saga are the men who made it all possible — a host of astonishing characters: Van Horne, the powerhouse behind the vision of a transcontinental railroad; Rogers, the eccentric surveyor; Onderdonk, the cool New Yorker; Stephen, the most emotional of businessmen; Father Lacombe, the black-robed voyageur; Sam Steele, of the North West Mounted Police; Gabriel Dumont, the Prince of the Prairies; more than 7,000 Chinese workers, toiling and dying in the canyons of the Fraser Valley; and many more — land sharks, construction geniuses, politicians, and entrepreneurs — all of whom played a role in the founding of the new Canada west of Ontario.
