A lobster is heavily cephalized, with eyes, antennae, multiple mouthparts, and the brain (inside the armoured exoskeleton), all concentrated at the animal's head end. Cephalization is an evolutionary trend in animals that, over many generations, the special sense organs and nerve ganglia become concentrated towards the front of the body where ...
In the American lobster, endogenous morphine is found in the haemolymph and ventral nerve cord. In lobsters which have had a pereiopod (walking leg) cut off or been injected with the irritant lipopolysaccharide, the endogenous morphine levels initially increased by 24% for haemolymph and 48% for the nerve cord.

Lobster anatomy includes two main body parts: the cephalothorax and the abdomen. The cephalothorax fuses the head and the thorax, both of which are covered by a chitinous carapace. The lobster's head bears antennae, antennules, mandibles, the first and second maxillae. The head also bears the (usually stalked) compound eyes. Because lobsters ...
Lobsters have two urinary bladders, located on either side of the head. Lobsters use scents to communicate what and where they are, and those scents are in the urine. They project long plumes of urine 1–2 meters (3 ft 3 in – 6 ft 7 in) in front of them, and do so when they detect a rival or a potential mate in the area. [18]
Scientists have created a full map of an adult brain for the first time.. The 3D model of all of the neurons of a fruit fly, and the 50 million connections between them, is the first time that ...
The map shows how the brain’s 140,000 neurons, or nerve cells, make close to 50 million connections between them. By comparison, the human brain contains around 87 billion neurons.
BrainMaps is an NIH-funded interactive zoomable high-resolution digital brain atlas and virtual microscope that is based on more than 140 million megapixels (140 terabytes) of scanned images of serial sections of both primate and non-primate brains and that is integrated with a high-speed database for querying and retrieving data about brain ...
Now, after the lab team’s decade of close collaboration with scientists at Google, that data has turned into the most detailed map of a human brain sample ever created. 300 million images. The ...
