Sentences with phrase «even human neurons»
To model the neurons, we'd have to measure from them, but this turns out to be more difficult for C. elegans than for mouse or even human neurons.

If the human quest is reduced to electrons dancing along wires and computational patterns crossing a population of neurons, does such a «story» justify even caring whether our society attains the success of a complex adaptive system?
In another example, he uses the example of human vision: the cortex predicts what should be seen and the mind fills in the gaps; in other words interpretation takes place according to expectation, so context even changes the way that neurons function.
As a result, the cerebellum in apes and humans contains far more neurons than that of a monkey, even when the brain is scaled up to the size it would be in an ape.
There are between 100 billion and 200 billion neurons in a human brain, so even at only a second per neuron, this will require tens of thousands of years.
Since olfactory sensory neurons regenerate throughout life, even in humans, the investigators were able to measure neuron regeneration in specific animal models.
«Worms, mice, humans, and even fruit flies show similar effects of intoxication at similar alcohol concentrations,» he says, and human neurons contain a switch similar to that in C. elegans.
Their end goal is to identify specific populations of neurons in the fruit fly brain that are necessary for emotion primitives — and whether these functions are conserved in higher organisms, such as mice or even humans.
The method could also help biologists understand how tissues change subtly during embryonic development — and even help map the maze of neurons that wire the human brain.
Researchers at the Salk Institute for Biological Studies recently found that the DNA sequence in human neurons can vary not only from that of the rest of the body but even from one brain cell to the next.
A region of the gene that produces the PACAP38 protein has held nearly constant, even in humans, presumably because the protein plays diverse roles in neuron communication and is essential for normal development of the cerebellum, affecting brain cell migration, for example.
These so - called bioreactors, and the mini-brains they foster, should open other new and valuable windows into human brain development, brain disorders and drug testing — and perhaps even produce neurons for treatment of Parkinson's disease and other disorders, the investigators say.
«On the basis of individual neurons of the brain, humans may indeed have a far more active, or even more complex, transcription profile than chimpanzee,» the authors note.
«Even though they're mice, we see these human cells that appear to be connecting to other neurons.»
Illogical as it is, the idea that neurons could be wirelessly and remotely activated by someone other the owner of those neurons disturbs me even though I know drugs are commonly used to do much the same thing in humans.
In terms of brain simulation, the challenges are even bigger: The world's fourth most powerful supercomputer took 40 minutes to model one second of brain activity in a simulated network containing 1.73 billion neurons and over a trillion synapses, yet this represents just one per cent of neuronal networks in the human brain.
