Connectionism
Connectionism: A theory of information processing that is based on the neurophysiology of the brain. The basic tenets of connectionism are that signals are processed by elementary units (in this case, neurons), processing units are connected in parallel to other processing units, and connections between processing units are weighted. The weights may be hard-wired, learned, or both, and they represent the strengths of connection (either excitatory or inhibitory) between two units.

Connective tissue: A material made up of fibers forming a framework and support structure for body tissues and organs. Connective tissue surrounds many organs. Cartilage and bone are specialized forms of connective tissue. All connective tissue is derived from mesoderm, the middle germ cell layer in the embryo.

- Connexin
Connexin: A subunit of connexon, a protein that forms a gap junction, a channel that permits ions and small molecules to move between adjacent cells. The connexins are important to intercellular communication. Historically, gap junctions were first characterized by EM (electron microscopy). They appeared to be specialized structures in the plasma membranes of cells in […]
