If firing rate is from 1 Hz to 200 Hz, 100 trillion to 20 quadrillion synaptic firings. Neuronal (say, measured from soma) firings will add up to 86 billion to 17.2 trillion action potentials per second. It important to remember, that synaptic firings "sum up" in soma or interfere between each other, so the are more of those. Read more: ...

In my opinion you should try low input library prep protocols because in my experience even with a decent quantity of RNA, standardizing the sequencing is not an easy job. The manual says that this kit works with 10-20ng of RNA; always assume the higher limit to be true. There is a higher chance of loss (relative) during extraction also. Try doing ...

as far as I know the brain processes data in stages the neurons themselves are not purely binary as in a computer in that every action has a predetermined output. the neuron response tends to be goverened by sigmoid function output and hence the use of this function in artificial neural networks. further, the synapses have strengths that is depended on the ...

The brain activity is electric and chemical. The male adult human brain contains about 86 billion neurons (Azevedo et al). There is about 100 trillion connections between them. Solving a puzzle like that is not easy.. what sort of breakthroughs would be necessary to intercept these signals and interpret them as exact thoughts? What you are referring to ...

There is little neurological evidence that finds a difference between men and women. However there are psychological studies that do find a small difference in mental strengths. This interesting TED talk debunking pyscological myths by a lecturer from the University of Liverpool discusses the pyscological differences between men and women. Males and ...

While action potentials are usually binary, you should note that synaptic communication between neurons is generally not binary. Most synapses work by neurotransmittors, and this is a chemically mediated graded response that, for example, act on voltage-gated ion channels. So even though action potentials are often binary, communication between neurons are ...

First of all, I would like to point out that making analogy between digital computers and the brain is often very misleading. That being said, my answer is, some scientists believe so, some don't. Several things to consider: Some neural systems are not spiking. C. elegans for example has a nervous system that is entirely analogue. Human nervous system ...

The hippocampus helps to solidify the pattern of connections that form a memory but the memory itself depends on the solidification of connections between the individual brain cells". This refers to the phenomenon called Long Term Potentiation which regulates synaptic strength between neurons. Certain patterns of firing (high frequency) causes the post ...
