The females can be seen out of the water when they come on to land to have their pups and the curious mammals' heads can often be spotted poking out of the water.
In mammals, "head-direction cells" are thought to support this process, but despite 30 years of research, no evidence for a goal direction representation has been reported [ 1, 2].
Huff sculpted a number of prehistoric animals (one-sixth actual size) for six dioramas, as well as five life-size reconstructions ofextinct mammal heads, and one very large reliefdepicting two American lions attacking a giant bison.
Remove the skin from a mammal's head as you would the rest of the body, but for lizards, fish, and birds, you'll need to remove the brain, eyes, and tongue and leave the shape of the head intact for preservation.
During his rounds, Mr. DerHohannesian tended to shoot the game's virtual mammals in the head or the heart as they galloped across the screen.
Mammals have similar "head direction cells" but this is a first for flies.
Musk oxen are stocky mammals with large heads, short necks, and short, stout legs.
The passenger pigeon was hunted to extinction in North America in the 19th century—and hundreds of mammals are now headed for the same fate.
We are just a couple of hairy mammals with big heads—and, after all, what is a little difference in brain size, compared to, say, a spider's intricate mating rituals, impressive silk-secreting apparatus, and complex web design?
McAlpine and colleagues added that small headed mammals may depend on the slope of ITD functions instead of the peaks to localize sound.
We identified hybrid transcripts of the AZGP1 and GJE1 genes on human chromosome 7 (manuscript in preparation) and are intrigued that the orthologues of these genes in non-primate mammals reside in a head-to-head manner.
