Quotes About Biology

The amygdala is one of those brain structures that a lot of people know a little bit about, and there's a definite tendency to conflate the amygdala and the fear response itself - as if the amygdala, and the amygdala alone, 'causes' fear.

As a general rule, biology tends to be conservative. It's rare that evolution 'invents' the same process several times.

I have never been a fan of science fiction. For me, fiction has to explore the combinatorial possibilities of people interacting under the constraints imposed by our biology and history. When an author is free to suspend the constraints, it's tennis without a net.

Synaptic summation is the technical term used in neurophysiology for those instances in which some neuron C is fired only by a combination of neurons A and B.

I've been around a long time, and I've been interested in memory for a long time. And one of my earlier interests in molecular biology of memory led me to define the switch that converts short term to long term memory.

We finally understand in general terms how a cell is organized, how its specialized organs function in a well integrated manner to insure its survival and replication.

A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.

It's terrifying the way molecular biology has become more and more jargon ridden. But I strongly believe that my book can be read by the intelligent layman. I want everyone who bought a copy of 'A Brief History of Time' to buy a copy of 'Genome'.

As part of our dedication to safety engineering in biology, we're trying to get better at creating physically contained test systems to develop something that eventually will be so biologically contained that we won't need physical containment anymore.

The testosterone levels of a normal male can be anywhere from 300-1,000 nanograms. For the average female, it's 10-70. Mine is around 7.

I was asked to do some studies to see if I was different. And I do have more male testosterone than the average woman does. Whether that makes me more aggressive, I don't know.

I think that testosterone is a rare poison.

Check your testosterone levels. Every study on evolutionary psychology has correlated testosterone levels with dominance.

Every time you cuddle with your children, you're likely to be driving down your testosterone.

I'm quite testosterone intolerant, I just don't like it.

The electrical forces turned the key that unlocked the repressed genes.

Information, and a monumental amount of it, is clearly passed from the body to the blastema.

Fortified by our new knowledge that electricity controlled growth in bone, we returned instead to the nerves, taking a closer look at how their currents stimulated regrowth.

This experiment demonstrated unequivocally that there was a real electric current flowing along the salamander's foreleg, and it virtually proved that the current was semiconducting. In fact, the half-dozen tests I'd performed supported every point of my hypothesis.

Burr and Lund advanced similar theories of an electrodynamic field,called by Burr the field of life or L-field, which held the shape of anorganism just as a mold determines the shape of a gelatin dessert."When we meet a friend we have not seen for six months there is notone molecule in his face which was there when we last saw him," Burrwrote. "But, thanks to his controlling L-field, the new molecules havefallen into the old, familiar pattern and we can recognize his face.

It seems reasonable that understanding what comes out of the blastema would be easier if we understood what goes into it, so the other major questions about regeneration have always been: What stimulates the blastema to form? And where do its cells come from?

Mother's milk, time-tested for millions of years, is the best nutrient for babies because it is nature's perfect food.

The Human Body, Superhuman and Instincts to Threads

from natural selection's point of view, status assistance is the main purpose of friendship.
