Many technical solutions are bio-inspired. Octopus-inspired robotic arms belong to continuum robots which used in minimally invasive surgery or for system restoration areas difficult-to-access. Continuum robot missions bounded with their motions, whereby the motion of is controlled by humans via wireless communication. In case a lost connection, autonomy required. Distributed control and distributed decision-making mechanisms based on artificial intelligence approaches can be promising solution achieve systems increase resilience. However these methods not well investigated yet. Octopuses living example natural but learning also fully understood Our major interest investigating Artificial Intelligence as basis improving resilience complex systems. We decided use physical prototype that able perform some basic movements our research. The idea research how empowered combine into sequences motions itself. For experimental investigations suitable has selected, its implemented automated. this paper, we give an overview combining different fields research, such 98 publications. provide detailed description models literature reviewed, discuss aspects prototypes robots.

Visualizing neuroimaging data is a key step in evaluating quality, interpreting results, and communicating findings. This survey focuses on diffusion MRI tractography, which has been widely used both research clinical domains within the community. With an increasing number of tractography tools software, navigating this landscape poses challenge, especially for newcomers. A systematic exploration diverse range features proposed across 27 tools, delving into their main purpose examining presence or absence prevalent visualization interactive techniques. The findings are structured taxonomy, providing comprehensive overview. Insights derived from analysis will help (novice) researchers, clinicians, developers identifying knowledge gaps tools.

As a major excitatory neurotransmitter in the cephalopod visual system, glutamate signaling is facilitated by ionotropic receptors, such as α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors (AMPAR). In cephalopods with large and well-developed brains, optic lobes (OL) mainly process inputs are involved learning memory. Although presence of AMPAR squid OL has been reported, organization specific AMPAR-containing neurons remains unknown. This study aimed to investigate immunocytochemical localization AMPA receptor subtype 2/3-immunoreactive (GluR2/3-IR) Pacific flying (Tordarodes pacificus). Morphologically diverse GluR2/3-IR were predominantly located tangential zone medulla. Medium-to-large also detected. The distribution patterns cell morphologies calcium-binding protein (CBP)-IR neurons, specifically calbindin-D28K (CB)-, calretinin (CR)-, parvalbumin (PV)-IR similar those neurons. However, two-color immunofluorescence revealed that did not colocalize CBP-IR Furthermore, localizations types do express CB, CR, or PV determined. These findings further contribute existing data on glutamatergic systems provide new insights for understanding processing mechanisms cephalopods.
