Spike Recorder vs Stochastic Signal Processing

Let’s face it. The brain is complex, but it is extremely fascinating. To study the brain, you typically have to be a graduate student at a major university. But not any more! Backyard Brains enables everyone to be a neuroscientist! Coupled with our SpikerBox you can order at: http://backyardbrains.com this app allows you to view, hear, record and analyze actual neural signals. Both from individual neurons and muscles. Backyard Brains provides affordable neuroscience experiment kits for students of all ages to learn (hands-on) about electrophysiology. Now everyone from schoolchildren to grad students and every grade in between can experiment with similar tools used by real neuroscientists worldwide! By following a few simple steps, everyone can experience first-hand how the brain communicates with our senses, memories, hopes, and desires. Our iOS application includes both long continuous and threshold views, and once you have recorded your data, you can analyze the neural spike trains, measure reaction times, and calculate statistics just like professional neuroscientists! Do let us know us know about your experiments. Note: The application normally picks up input through the the iPhone's built-in microphone. If you want to plug directly into your SpikerBox, or any audio device, you need a custom male-to-male headphone cable (a normal one won't work), available from our website. It has to do with routing and filtering an output channel to an input channel.

Speech, music, seismic vibrations, oil prices, and climate measurements are all examples of stochastic (random) signals. In this textbook—intended for individuals with prior training in introductory signal processing and introductory probability theory—we develop techniques to process such signals to extract useful information. We present case studies ranging from music to photographic images to oil prices to climate data to the motion of individual biomolecules. This textbook, as an interactive textbook ("iBook"), makes use of your device's ability to display dynamic information through films and animations and to hear the results of the techniques applied to music. At the end of every chapter there are homework problems ranging from easy to "olympic". We make use of your device's interactive capabilities to offer 59 laboratory experiments in signal processing. The experiments use the camera, the microphone, the speakers, and the graphical user interface. These experiments are not simulations; they are examples of real digital processing of signals in your device. In this time of at-home and online learning, this is the way to learn signal processing through study and experimentation.
