REGENERATIVE EXPERT. "Freshwater planarians can perform all manner of amazing tricks when it comes to regeneration. Thomas Hunt Morgan was one of the first people to systematically study planarian regeneration in the late 19th century. Inspired by the observations of Harriet Randolph, he defined the minimal size of a fragment capable of regeneration as 1/279th of the intact animal’s volume." https://lnkd.in/deKxCqJ View in LinkedIn

NEW BRAIN. "Planarian flatworms are a popular system for research into the molecular mechanisms that enable these complex organisms to regenerate their entire body, including the brain." https://lnkd.in/dy37eKV View in LinkedIn

INFORMATION. "One of the most interesting capabilities of living systems is processing information." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

TWO TYPES OF INFORMATION. " Biological information in multicellular organisms comes in at least two types: spatial information, needed to create and maintain specific anatomical structures during embryogenesis and regeneration; and temporal information, abstracted and stored from environmental stimuli over time by the central nervous system (CNS)." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

CYBERNETICS. "The intersection of these two fundamental processes has implications for basic neurobiology and engineering of the brain–body interface, for the synthetic bioengineering of cybernetic systems and for the biomedicine of degenerative brain disease." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

IMMINENT ISSUES. "For example, what happens to the personality and mental content of an adult patient with decades of stored memories when their brain is repopulated by the descendants of implanted stem cells." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

MODEL SYSTEM. "Free-living, planarian flatworms represent the ‘first’ class of organism to have a centralized brain with true synaptic transmission, and share the majority of neurotransmitters that occur in vertebrate brains." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

NEW HEAD REGENERATION. "Adult stem cell populations (neoblasts) underlie their remarkable regenerative abilities, and whole worms can regenerate from only a small proportion of the adult worm: a cut off (or damaged) head is rebuilt perfectly within few days." http://jeb.biologists.org/content/216/20/3799 View in LinkedIn

METAMORPHOSIS BRAINS. "Studies have identified several insect organisms in which memories survive the drastic reorganization of metamorphosis." This defies thinking about. http://jeb.biologists.org/content/216/20/3799 View in LinkedIn
