... 'Flat' EEG means nothing. Well, at least EEG is of limited use in excluding every level of conscious awareness. EEG only measures cortical, post-synnaptic activity summated over large populations of neurons. It is blind to the entire subcortical volume, and even to large parts of the cortex.

>how do you connect to the one pathway which is so extremely small and uncooperative?
Well, that's the problem. We can't, at the moment.
>from where does an electric charge comes from ?
The electric charge comes from a difference in extra- and intracellular relative concentrations of charged ions. The main contributers are sodium and potassium (and to some extent, chlorine and calcium). Sodium is pumped out of the cell and potassium into the cell. During an action potential (a 'signal' traveling across a neuron) sodium floods into the cell, which is measurable as a voltage change from outside the cell.

Awesome. I'm actually involved in a project with DBS and OCD patients (not on the clinical side though, but we do measurements from the accumbens).

The clinical benefits are obvious though, and the success rate is high. It's also fairly versatile and can be used for a verity of disorders, not just psychiatric ones.

Quite a lot is known about the specific pathways from senses to their respective parts of the cortex, the different cellular pathways involved, and decoding of stimuli by primary sensory areas. That's not really the problem (although of course our knowledge isn't perfect either). The difficulty lies in connecting electrical equipment to neuronal ensembles in a neuron-specific manner. One electrode going into one neuron is extremely unstable, and the body tends to reject exogenous apparatuses, causing neurons in direct contact to die off.

I'd say neuroscience would look better if neurology is what you're going for. You would have already taken classes like neuroanatomy and such which would make med-school easier. Most neuroscience programs also include a lot of physiology and general anatomy, a lot of biology and biochemistry, but not stuff like ecology.

>Do you think that any further science breakthroughs in the brain will just be fixing broken brains?
Sure, the end point is fixing pathology. That's not the only part where breakthroughs are realized though. I see a breakthrough as a sudden increase in our knowledge.
>On a related note do think humans can build a better brain?
In what sense? Design one from the ground up? That's what the people in robotics are doing.

Well, not that many. You'd have more job prospects at pharmaceutical companies, but that's about it. You should choose the major you like best though. It's important that you're not stuck doing something you have no desire to do for the rest of your life.

Not enough neuroscience talk on this board.

Lets change that. Ask questions, and answer to the best of your knowledge.

>No problem, man, but the credibility of your science is at stake..
Actually, my respective field is neuroscience.
>I asked you to prove that psychology, as a science, is able to make equally solid predictions as any other science
Predictions are probabilistic, not deterministic, even in physics. That's the whole point of having statistical methods to make decisions about rejecting the null hypothesis.

There is no clear-cut point where psychology ends and biology begins. It is the object of study which defines the field.
>If it's mostly biologically fixed, then it's biological, not psychological.
That's a false dichotomy. 'Psychological' does not imply there's no genetic influence, it merely indicates that it is externally measurable through behavior, and that it involves the mind (as a function of the brain). Genetic determanants are something for biologists, but the behavioral manifestation is something for psychologists.
>Also, make a list of 10 predictions made by psychology that will always hold.
I don't like your forceful tone.

Biology and chemistry are an integral part of psychology, but the object of study differs. Psychologists are interested in behavior, cognition and perception. Biology only forms the basis, but the experimental methods are qualitatively different.

Right, but in order to present at a large conference you have to have an established record of publications. You can't just walk in and say "hey, here's some stuff I found" without it being validated. Yes, new results are presented at conferences, but they are almost always followed by publication.

That's because you are, excuse my language, an ignorant fuck. I'm done talking to you.

FYI: yes. [>>3000764]
