Bubble wrap Bubble wrap Bubble wrap is a pliable transparent plastic material used for packing fragile items. Regularly spaced, protruding air-filled hemispheres (bubbles) provide cushioning for fragile items. "Bubble wrap" is a generic trademark owned by Sealed Air Corporation. In 1957 two inventors named Alfred Fielding and Marc Chavannes were attempting to create a three-dimensional plastic wallpaper. Although the idea was a failure, they found that what they did make could be used as packing material. Sealed Air Corp. was co-founded by Alfred Fielding in 1960. The term is used generically for similar products, such as bubble pack, bubble paper, air bubble
Methods used to study memory brain. Due to the use of large, surgically implanted devices this technique is generally used on primates, however the use of small cryotip implants has implications for use in rats. This exciting new technology allows for reversible lesions, which removes variations between animals so that better causal relationships can be shown. Animals can act as their own controls and this is ideal for any neuroscientific research. The neurotoxic lesion technique has proven to be essential for studying the neural basis of behavior and memory in animals. Neurotoxins can be used to selectively damage very specific nerve tracts in the brain.
