Is anyone on tonight who understands neural pathways and CNS exhaustion? I have questions related to weightlifting.

ADHD is universally accepted to be a legitimate disease by experts in the fields of mental and neurological health. Someone with ADHD has distinct and recognizable neurological differences.

However, ADHD is very much over-diagnosed.

What field you're in does not change the nature of the thing being studied, though. Modern psychology students are not even allowed to graduate without becoming reasonably educated in neuroscience, and that brings with it chemistry, physics, and biology.

It isn't an intentional thing. Sometimes someone will say something or make some subtle (but commonly understood) motion and I'll recognize it as part of my studies, but that's it.

Other than that, my studies have certainly made me more cautious about making generalizations and predictions, as well as citing statistics in casual conversation.

You should be careful about this line of thinking. Because of hindsight bias, it's easy to believe that your education has allowed you to manipulate or understand people, even if in reality you just used common unconscious communication and intuitive conversational cues to gain that understanding or control.

>Some researchers believe that creativity is the outcome of the same cognitive processes as intelligence, and is only judged as creativity in terms of its consequences others believe that creativity and intelligence are two distinct mental processes.

This is /sci/; I think you're looking for /pseudosci/ or perhaps /popsci/.

Hey,

College starting next week. If I want to study neuroscience, what major should I pursue?

Psychology/Biology/Chemistry/Math(?)

Some say it would be better to take Psychology because you're pretty much guaranteed a good GPA (if you're not a total retard).

At the same time, biology (You get to learn some neuroanatomy, neurochemistry and so on) seems to be a better fundament (from a science perspective), but possibly harder to achieve that 4.0 GPA.

Since I'm eurofag I'm transfering directly into sophomore year, so I don't have that much time to declare a major! Help appreciated

So the brain has 100 billion neurons, and the most complex artificial neural net (http://en.wikipedia.org/wiki/Artificial_neural_network)) to date will have 1 billion (http://www.artificialbrains.com/spinnaker).).

It's easy to say that the artificial neural network (ANN) has 1% of the complexity of the brain, but it's not that simple. What defines the complexity of a system is not merely the number of units in the system, but the number of meaningful interactions that can happen between the units.

For instance, if each unit in a system can interact with each other:
3 units = 3 possible interactions
5 units = 10 possible interactions
10 units = 45 possible interactions
100 units = 4950 possible interactions
1,000,000 units = 499,999,950,000 possible interactions

It's clear to see that for a linear increase of unit number, the increase in interaction number is nonlinear, and thus far more important at large numbers.
10 is 10% of 100, but 45 is only 0.9%, and the significance decreases as size of the system (number of units) increase.

I want to apply this logic to brains and ANNs. Biological neurons have between 5,000 and 200,000 inputs from other neurons. Assuming that the ANN cited above functions on a similar number of inputs, I want to:
1) quantify the complexity of the brain in terms of interactions
2) do the same for an equivalent system of only 1 billion units
3) work out difference in complexity between the two systems

Unfortunately, my math skills end at the previous example =(
I am hopeful that someone here can help me or point me in the right direction!

any /sci/ faggots want to debate some neurochemistry?

first claim: not only is aspartame not bad for you, but its good for you as it breaks down into two vital amino acids

i actually believe that the cokes, and doritos of the world throwin this crazy neurotransmitter shit into our food are trying to help form the overman, because this shit is actually good for us
