The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that result from simultaneous “excitations”, whose pr...
Kingdon Animalia comprises, the metazoans, that aremulticellular organisms having eukaryotic cells with a nucleus, a cell membrane, and organelles such as mitochondria. They are heterotrophic (obtain food from external sources) and utilize oxygen for energy catabolism. ...
