Motion perception lies at the heart of the scientific study of vision. The motion aftereffect (MAE) is the appearance of directional movement in a stationary object or scene after the viewer has been exposed to viusal motion in the opposite direction. For example, after one has looked at a waterfall for a period of time, the scene beside the waterfall may appear to move upward when one's gaze is transfered to it. Although the phenomenon seems simple, research has revealed copmlexities in the underlying mechanisms, and offered general lessons about how the brain processes visual information. In the 1990s alone, more than 200 papers have been published on MAE, largely inspired by improved techniques for examining brain electrophysiology and by emerging new theories of motion perception.

Motion perception lies at the heart of the scientific study of vision. The motion aftereffect (MAE), probably the best known phenomenon in the study of visual illusions, is the appearance of directional movement in a stationary object or scene after the viewer has been exposed to visual motion in the opposite direction. For example, after one has looked at a waterfall for a period of time, the scene beside the waterfall may appear to move upward when ones gaze is transferred to it. Although the phenomenon seems simple, research has revealed surprising complexities in the underlying mechanisms, and offered general lessons about how the brain processes visual information. In the last decade alone, more than 200 papers have been published on MAE, largely inspired by improved techniques for examining brain electrophysiology and by emerging new theories of motion perception. The contributors to this volume are all active researchers who have helped to shape the modern conception of MAE.

When ones looks at a moving stimulus for a long duration and immediately after that looks at a stationary stimulus, the stationary stimulus appears to be moving in the opposite direction. This perceptual aftereffect is known as the motion aftereffect or the waterfall illusion. This perceptual aftereffect has been discussed widely and there are numerous research publications available discussing the phenomenon and underlying mechanisms. Here I present an explanation for motion aftereffect that might be after all the true explanation. Brain tissue is an excitable tissue with excitation spreading via neural synaptic connectivity, diffusion of ions in the free extracellular space and glial mechanisms of potassium buffering and calcium responses. A prolonged spiking activity of neurons in a tissue can trigger spread of excitability. Within a tissue volume there exist neural cells that are selective to opposite stimuli, like orthogonal orientations and opposite directions of motion. Direction selective neurons would adapt to their preferred stimulus and exhibit a decrease in responsiveness. While doing so these would trigger a spread of tissue excitability towards neurons selective to opposite direction of motion. The opposite direction selective neurons would exhibit an increase in responsiveness due to an increase in surrounding tissue excitability. It is suggested here that this leads to motion aftereffect, that is, following adaptation when a stationary stimulus is viewed it gives rise to a perception of motion in opposite direction.

After Effects CS5.5 Update: /tv.adobe.com/show/after-effects-cs55-new-creative-techniques/ Chris and Trish Meyer have created a series of videos demonstrating how to use their favorite new and enhanced features in After Effects CS5.5. Virtually all of these videos use exercise files from Creating Motion Graphics with After Effects (5th Edition for CS5) as their starting point, extending the usefulness of this book for its owners. These videos may be viewed for free on AdobeTV. * 5th Edition of best-selling After Effects book by renowned authors Trish and Chris Meyer covers the important updates in After Effects CS4 and CS5 * Covers both essential and advanced techniques, from basic layer manipulation and animation through keying, motion tracking, and color management * The downloadable resources are packed with project files for version CS5, source materials, and nearly 200 pages of bonus chapters Trish and Chris Meyer share over 17 years of hard-earned, real-world film and video production experience inside this critically acclaimed text. More than a step-by-step review of the features in AE, readers will learn how the program thinks so that they can realize their own visions more quickly and efficiently. This full-color book is packed with tips, gotchas, and sage advice that will help users thrive no matter what projects they might encounter. Creating Motion Graphics 5th Edition has been thoroughly revised to reflect the new features introduced in both After Effects CS4 and CS5. New chapters cover the revolutionary new Roto Brush feature, as well as mocha and mocha shape. The 3D section has been expanded to include working with 3D effects such as Digieffects FreeForm plus workflows including Adobe Repoussé, Vanishing Point Exchange, and 3D model import using Adobe Photoshop Extended. The print version is also accompanied by downloadable resources that contain project files and source materials for all the techniques demonstrated in the book, as well as nearly 200 pages of bonus chapters on subjects such as expressions, scripting, and effects. Subjects include: Animation Techniques; Layer Management; Modes, Masks, and Mattes; Mastering 3D Space; Text Animation; Effects & Presets; Painting and Rotoscoping; Parenting, Nesting, and Collapsing; Color Management and Video Essentials; Motion Tracking and Keying; Working with Audio; Integrating with 3D Applications; Puppet Tools; Expressions; Exporting and Rendering; and much more.
