| retino tectal connection | A problem that has exercised developmental biologists is the way in which nerve fibres from the developing retina are mapped on to the tectum of the brain. There seems to be a good positioning system in operation and a variety of mechanisms probably operate, including control of the fasciculation of fibres in the optic nerve and some specific recognition of the correct target area by the nerve growth cone.

| grid connection | Joining a plant that generates electric power to a utility system so that electricity can flow in either direction between the utility system and the plant. (05 Dec 1998) |
| clamp connection | <microbiology> In many basidiomycete fungi a short lateral branch of a binucleate cell develops. This is the developing clamp connection. One of the nuclei migrates into it. Both nuclei then undergo simultaneous mitosis so that one end of the cell contains two daughter nuclei from each of the parental nuclei. The nucleus in the branch and the two nuclei are separated off from the centre of the cell by septa. A single nucleus remains in the central region. The clamp connection then extends towards and fuses with the central section so that a binucleate cell is reformed. (18 Nov 1997) |
