The new calculation and analysis method analyzes the change of the sensory state of the cuttlefish.

German scientists recently reported real-time quantification of the dilating state of thousands of cuttlefish skin pigment cells in the British journal Nature.
studies have shown that changes in the sensory state of the cuttlefish can be reflected in its complex physiological changes.
these findings increase human understanding of the correlation between the sensory state of cuttlefish and physiological changes.
cuttlefish and octopuses have an unparalleled ability to change the color and texture of the skin in order to disguise or communicate, thanks to the controlled extrusion of countless pigment cells.
track the expansion of these pigment cells, can quantitatively describe the real-time perception of cuttlefish, and it is even expected to become a neurodescription substitute indicator.
, Gilles Lauren, a scientist at the Map Brain Institute in Germany, and colleagues developed a computational and analytical method associated with this and obtained data information from free-acting cuttlefish.
team spent several weeks photographing six cuttlefish in the tank and coloring the pigment cells of the cuttlefish's back-side coat film on a single-cell scale at a rate of 60 frames per second.
at the same time, the researchers also moved the position of the hand above the cuttlefish to experience a dark-to-light process, which tracks the dynamics of the cuttlefish.
they repeated the process several times and reported that the cuttlefish produced the same target pattern each time they were stimulated.
