From nerve net to nerve ring, nerve cord and brain — evolution of the nervous system

Nature Reviews Neuroscience, 2015
The puzzle of how complex nervous systems emerged remains unsolved. Comparative studies of neurodevelopment in cnidarians and bilaterians suggest that this process began with distinct integration centres that evolved on opposite ends of an initial nerve net.

The endodermal nerve net of Scyphozoa

Journal of Morphology, 1971
AbstractThe endodermal nerve nets of the scyphozoan jellyfish Phacellophora camtschatica and Cyanea capillata were stained with methylene blue. Small animals (3–7.5 cm in diameter) stained easily. The endodermal nerve net of both species is a synaptic net consisting of bipolar and some few tripolar nerve cells with unbranched neurites.

Nerve Cells or Nerve Nets?

1991
Abstract By the middle of the nineteenth century, the task of understanding the nerve cell as a cellular unit depended on answering several questions: (1) how do axis cylinders arise from nerve cells? (2) what is the extent and significance of the pale branched processes of nerve cells?

Improved U-Net Model for Nerve Segmentation

2017
Noticeable gains in computer vision have been made as a result of the large-scale datasets and deep convolutional neural networks (CNNs). CNNs have been used in a wide variety of tasks, for instance, recognition, detection, and segmentation. Recently, due to the open medical images datasets, CNNs have been used in Computer Aided Detection (CADe) to ...

Changes in conduction velocity within a nerve net

Journal of Neurobiology, 1974
AbstractConduction velocity within the through‐conducting nerve net of the sea anemone Calamactis praelongus is altered as a result of the passage of one or more impulses. Facilitation of conduction velocity occurs when the second evoked impulse follows the first by less than 2 sec.

Large Artificial Nerve Net (LANNET)

IEEE Transactions on Military Electronics, 1963
This report describes the implementation of a high speed self-organizing system based on the reinforcement principle. The self-organizing binary logical network is used as the primary component in the system. The learning system is a 1024 decision element netwolk with a general purpose program to enable the operator to simulate a large number of ...

Ultrastructural reconstruction of the endodermal nerve net of Hydra vulgaris

Current Biology
The cnidarian Hydra vulgaris has a simple nervous system with as little as a few hundred neurons distributed in two nerve nets in the ectoderm and endoderm. Using this simple neural chassis, Hydra can paradoxically perform relatively sophisticated behaviors, such as somersaulting and feeding.
