mammalian
cells genetically engineered with a bioluminescent gene taken out of deep-sea jellyfish.
Terrible news for the dinosaurs, but great news for our
mammalian
ancestors, who flourished in the niches left empty by the dinosaurs.
I don't have time to explain, but to understand how a brain works, you have to understand how the first part of the
mammalian
neocortex works, how it is we store patterns and make predictions.
A
mammalian
fetus, if it loses a limb during the first trimester of pregnancy, will re-grow that limb.
But then one day I started thinking about the
mammalian
penis.
After all, if ideas about invertebrate skeletons can give us insights about
mammalian
reproductive systems, there could be lots of other wild and productive connections lurking out there just waiting to be found.
Though it was based on very little evidence, many scientists thought that all
mammalian
brains, including the human brain, were made in the same way, with a number of neurons that was always proportional to the size of the brain.
Now interestingly, there are a few
mammalian
species in which females have evolved specialized genitalia that doesn't allow for sexual coercion to take place.
But then, in the 1990s, studies starting showing, following the lead of Elizabeth Gould at Princeton and others, studies started showing the evidence of neurogenesis, the birth of new brain cells in the adult
mammalian
brain, first in the olfactory bulb, which is responsible for our sense of smell, then in the hippocampus involving short-term memory, and finally in the amygdala itself.
The human race has been around for about 200,000 years, and if she lives as long as a typical
mammalian
species, she would last for about two million years.
And what's more, the human race isn't a typical
mammalian
species.
The implication is that microbes can affect
mammalian
behavior.
And this is only mapping 10 percent of a
mammalian
neocortex.
Their explanation for this involves the uniquely
mammalian
activity of nursing.
Nor do monotremes, the third and arguably strangest example of
mammalian
birth.
So then we come along, we implant some
mammalian
cells that you can see in blue.
Their ancestors appeared around the same time as the first small mammals, and they were probably able to survive because they were evolving— and growing—at the same time as their
mammalian
predators.
We are one species of about five and a half thousand
mammalian
species that exist on planet Earth today.
They took up one quarter of the
mammalian
biomass.
They're even better models of environmental health, because not only the same
mammalian
biology, but they share your diet, largely.
Evidence is gradually accumulating that the majority of
mammalian
research animals, particularly rodents, are mentally stressed by their living conditions.
Natural selection has provided scientific explanations of traits as diverse as the
mammalian
eye, the bird’s wing, and the ability of plants to transform light into sugars.
Insects have a central ganglion that, like a
mammalian
midbrain, is involved in processing sensory information, selecting targets, and directing action.
Interestingly, in cultured mouse or human cells, the
mammalian
SIR2 gene determines a cell's response to DNA damage.
The
mammalian
SIR2 gene modulates this process, and higher levels of it dampen the cell death response.
Just like in yeast and worms,
mammalian
SIR2 promotes survival, in this case of cultured cells.
Does this mean that
mammalian
aging is at least partly caused by the gradual loss of cells and the accompanying failure of organs?
So, while complete reconstructions of a small region of the
mammalian
brain are feasible, structures like the cerebral cortex – with a surface area of 0.22 square meters and a thickness of between 1.5-4.5 millimeters – cannot be fully reconstructed.
Thus, although a true synaptome of the
mammalian
brain is a chimerical quest, it is possible that in the near future we will be able to construct a “silicon cortex,” a computerized machine based on a realistic model of the complete anatomical, physiological, and molecular design of the cortical circuit.
In neuroeconomics experiments that my lab has conducted, we have found that when a stranger places trust in another by making a considered monetary investment that can either be returned or stolen, our brains release an ancient
mammalian
hormone called oxytocin.
