The Nerve Net of the Actinozoa [PDF]

Journal of Experimental Biology, 1935
ABSTRACTStimulation of the column of the anemone Calliatis parasitica elicits a graded series of responses. Each response is primarily due to the action of a single set of muscles. The means by which this effect is produced is physiologically simple.

A new look at the architecture and dynamics of the Hydra nerve net [PDF]

bioRxiv, 2023
The Hydra nervous system is the paradigm of a “simple nerve net”. Nerve cells in Hydra, as in many cnidarian polyps, are organized in a nerve net extending throughout the body column.

Utilization of a Deep Learning Algorithm for Automated Segmentation of Median Nerve from Ultrasound Obtained from the Distal Forearm and Wrist [PDF]

Bioengineering
Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment, and ultrasound provides a fast, cost-efficient method for visualizing the median nerve.

ULTRASTRUCTURAL EVIDENCE OF POLARIZED SYNAPSES IN THE NERVE NET OF HYDRA [PDF]

Journal of Cell Biology, 1971
Synapses provide pathways of communication between cells throughout the animal kingdom wherever a nervous system is present. The most primitive or elementary nervous system that can be readily recognized is the nerve net of coelenterates .

Nerve net differentiation in medusa development of Podocoryne carnea

Scientia Marina, 2000
The phylum Cnidaria is the most primitive phylum with a well-developed nervous system. Planula larvae and polyps display a diffuse nerve net (plexus), which is densest in the polyp hypostome.
