Personality studies are typically investigated via the "big five" traits. Some attempts to legitimize the personality traits through biology have been pursued [1]. Following are some excerpts from a particular study that proposed a hypothesis and searched for confirmation in 116 subjects. Of course, this means we should be wary of confirmation bias when ...

There is no difference between "computational neuroscience" and "theoretical neuroscience" in practice. The two are almost always used interchangeably. Neuroinformatics, like bioinformatics, is more about managing data and designing analysis software (that's always somehow integrated with data storage and management). Generally, it is informational ...

I don't have an answer in terms of percentages, but I thought I could offer at least some insight I may have. Really cool question though, never really thought of this. So two ways to go about this answer. For one, when you close your eyes you immediately can register so called alpha waves from an EEG (electroencephalography). This was actually how EEG was ...

Vesicle count and spine morphology are two of the better-known predictors of synaptic strength. But they are not the whole story. Glia, like astrocytes can also modulate synaptic strength by releasing their own neurotransmitter or co-agonist, but you need more than just images to detect that process. There is also the matter of receptor distribution in ...

Cool question...really huge though. I'll have to revisit this as I find time to add more. For starters, I just saw an interesting link in @ForbiddenOverseer's question, "Is there any Personality theory that uses scientific methodology instead of subjective interpretations?" For some info on cerebral blood flow and extraversion, check out Johnson and ...

The initiation of SA node action potential is through slow Na+ channels (slow, inward depolarising current, note there are no fast Na channels. These pacemaker setting Na channels only act when it is VERY hyperpolarised, won't initiate otherwise). As the membrane potential rises, you get the additional opening of T-type calcium channels and then the opening ...

On a totally personal basis.. I know music stimulates the brain drastically. I've noticed those that seem to love learning tend to lean more toward Classic music or Techno... (that's a totally biased opinion though) On a researching note.. http://en.wikipedia.org/wiki/Biological_basis_of_personality The above link should be a great start for you! ...
