How does the brain's circuitry actually create conciousness? What is actually going on at the terminus of all the chemical reactions and processes that creates sensory experience? What about feelings such as pain, happiness, sadness or anger? Yep, I know these are the million dollar questions and there are not definitive answers (yet!), so I'm interested in hearing your ideas or any research/theories you find particularly interesting on the topic. Cheers!
So I have been working in an entirely different field for the last years and was never entirely sure about what I wanted to do with my life. I am certain at this point that I want to work in a field which involves, you know, nervous systems. Unsurprisingly, I am thinking of academia. [more inside]
I would like to get some book recommendations on the following topic: the connection between brain arousal states (am I using that term correctly?) (e.g. sleepy, alert, hyperalert/anxious), EEG states (e.g. theta, alpha, beta), and various neurotransmitters and perhaps even psychotropic medications. [more inside]
The brain is really good at keeping track of body position, limbs, etc., even when it's not looking at them. Is there a term that describes the equivalent ability as it relates to objects? E.g., I'm sitting at my desk right now and I know there's a plant behind me. I want a term for that ability! So far all I've got is "object propriception"
Hospice and palliative-care providers often tell patients' families and friends that as people die, hearing is the last sense to go. Is there any science behind the claim? [more inside]
When you read or think a lot or otherwise concentrate, and you get fatigued or sleepy, what exactly is happening biologically? Is it a matter of blood sugar depletion? Something else?
What's the best book to provide an up-to-date view on our current understanding of the human mind (and brain)? [more inside]
I have telescopic dreams once in a while - dreaming something only to realise that I'm dreaming, "wake up" in another dream, then sometimes switching back to the first dream or "waking up" to another dream entirely. They freak me out quite a bit as I'm never quite sure if or when I'm really awake. Why do these dreams happen? Is anything the matter? [more inside]
I just had an MRI and MRA in response to these issues, and the radiologist's report should be relayed to me in a day or two. I've already had one normal CT scan. I received a copy of all the images from this scan - should I look at them? [more inside]

Brain Training Games like Brain Age are a big hit lately -- Do you think they actually improve cognition? [more inside]
When it's really quiet as I try to fall asleep, I'll sometimes hear faint sounds that seem to have been things I'd heard earlier in the day, with what's almost like a residual effect. It mostly seems comprised of co-workers talking, TV/radio broadcasts, and the vocal parts of songs (which doesn't include "Helter Skelter"). It's almost like hearing one's own "inner voice" (at least, I'm assuming), but more faint and on auto pilot. Is this a fairly common occurrence, and what's the cause of it? [more inside]
What, why and how are Brain Sparks? [more inside]
Assume you had a list of different animal species, and you wanted to order it from most intelligent species to least. (1) What measure of intelligence would you use to compare different species--average number of neurons, for example, or ability to solve certain kinds of tests? Or something else entirely? (2) Can you give some examples of how some common farm, food, or pet animals might rank on the list? [more inside]
