The vertebrate retina contains four types of glia, each of which exhibits distinct morphological, developmental and antigenic characteristics.

In the age of computers and the Internet one of the most appealing theories of how mind is generated from the neurons of the brain is by the computation of large networks of connecting neurons. Olaf Sporns () coined the term “connectome;” it refers to the mapping of all neuronal connections. There are many large scientific projects.

Port Manteaux churns out silly new words when you feed it an idea or two. Enter a word (or two) above and you’ll get back a bunch of portmanteaux created by jamming together words that are conceptually related to your inputs. For example, enter "giraffe" and you’ll get back words like "gazellephant" and "gorilldebeest".

A newer definition arose with the growth of molecular biology. Here, epigenetics refers to mechanisms of gene regulation that determine the state of a cell and that are heritable through cell divisions but that do not involve changes in DNA sequence.
