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

Cu Thin Film Polyimide Heater for Nerve-Net Tactile Sensor
Proceedings, 2017 Tactile sensing is required for assistant robots. A new stacked sensor head was proposed which detects forces and thermal sensations with a nerve-net LSI chip.

Nerve net differentiation in medusa development of Podocoryne carnea [PDF]
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.

Dense and distributed neuropeptide network in the nerve net of Hydra vulgaris [PDF]
PLoS Computational BiologyNeuroscience has long emphasized synaptic transmission and physical wiring as the substrate of brain function and behavior. However, an additional layer of connectivity - a "chemical connectome" formed by neuropeptide-GPCR signaling - has been ...

Diffusion meets edge awareness: a unified framework for high-precision ultrasound nerve segmentation [PDF]
Frontiers in Digital HealthIntroductionNerve segmentation from ultrasound images is still challenging due to speckle noise, poor contrast, and unclear anatomical edges. These limitations have an adverse effect on deep learning segmentation models working on raw ultrasound data ...

In vivo replication of a fully functional nerve net in a clonally reproducing animal [PDF]
Communications BiologyNerve nets are considered the evolutionarily oldest form of nervous system. How such networks develop and how complex nervous systems become fully functional is largely unknown.

Deep learning for automatic segmentation of the inferior alveolar nerve using a hybrid CNN–transformer framework [PDF]
Scientific ReportsAccurate identification of the inferior alveolar nerve (IAN) is essential for preventing nerve injury during dental and maxillofacial procedures such as tooth extraction, implant placement, and orthognathic surgery.

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.
