Memory and the Microinvertebrates

  • Philip B. Applewhite
  • Harold J. Morowitz


The choice of an experimental organism in biology often determines what experiments can be performed, and thus may set limits on the physical level at which information can be gained. If the human brain with its 1010 neurons were chosen as the experimental object, the specification of all the neuronal interconnections would be too difficult and information about it at this level could not be obtained. Electron microscopy of the rat’s brain has been done, but an electron microscopic mapping of the entire rat’s brain is not feasible. Also, it is not convenient to use the smallest metazoan (50 μ) to study the gross chemical composition of a brain, nor is it convenient to insert electrodes in the smallest protozoan (5 μ). This is to say the experimental level one is working at eliminates certain organisms because of size restraints.
