The cubomedusan nervous system includes a centralized system of four rhopalia interconnected by a nerve ring, and peripheral nerve nets
in several parts of the medusa that serve motor, sensory, and likely modulatory functions (Skogh el al, 2006; Garm et ai, 2007a; Parkefelt and Ekstrom, 2009; Satterlie, 2011).
The tubulin-IR network followed this development of the circular muscle layer, but the neurites took a more random orientation to form a more morphologically nonpolarized nerve net structure.
The tubulin-IR neurites conformed to the classic diffuse nerve net arrangement.
Within the swim system of cubomedusae, the density of neurons in the velarial nerve net
appears to exceed that of the subumbrellar net (Satterlie, 2002).
However, the motor nerve net
that innervates the swim musculature crosses the interradii and perradii (Coates and Satterlie, in prep.
Thus, the presence of a peptidergic nerve net
over the entire tentacle could merely be a reflection of the uniform distribution of cnidocytes in the tentacles.
A subset of cells in the nerve net
of Hydra oligactis defined by a monoclonal antibody: its arrangement and development.
The acute inhibitory effect of the antibody on electrically stimulated luminescence means that the antibody binds to an antigen widely distributed in the luminescent endoderm or in the nerve net
that propagates the excitatory signals responsible for lighting up photocytes along the signal path (Anderson and Case, 1975).
In some preparations the myoepithelium that envelops the MNN neurons was removed to expose the nerve net
(Anderson and Schwab, 1984).
Minsky has built a machine for simulating learning by nerve nets
and has written a Princeton Ph.
each wavering color had its nerve nets

While at Yale, Ted spent summers at the Marine Biological Laboratory (MBL) in Woods Hole, where he investigated the functioning of nerve nets
in coelenterates and the structure and physiology of giant nerve fibers in annelids.
