Ask a Neuroscience Professor

In that we don't know what causes the subunits to switch out?

No in that the subunit switching has anything to do with critical period, or even enhances plasticity.
 
I've never measured plasticity in a petri dish, but wouldn't neurons with the 'younger' NMDA subunits be more plastic? I'd think a bit of transgenics would have answer that question years ago?
 
Good question. Can somebody answer it?
 
Forgive me if this has been asked before, I'd just like to get this in before I go to my classes.

I would like to go into neuroscience or more specifically neurolinguistics. I have a few questions on how best to get to the point at which I can take an active role in research. I'll finally be done with general studies requirements this semester, and I'm trying to figure out where to go from here.

What are the basic level courses I should take? Can I focus on neuroscience right out of the gate, or should I go into some more general biology and chemistry courses, first? How much math is used by theorists in the field, and which math?
 
How has your work effected the way you live your life (changed your views toward self/others/the universe/etc. & your behaviors)?
 
Is there a clear and precisely defined boarder between Nature and Nurture in the debate by the same name?
 
How does learning multiple languages affect the brain?

Don't know. Each language uses the same brain areas, even sign language. There is no obvious remapping or expansion of these areas that I could find reported.

Well neurolinguistics is probably more in a psychology dept. or Cog. Sci. Basically they use psychological testing and neuroimaging techniques. See what your school offers for undergrad majors. You could go psych. or biology (some like UCSD offer a neuroscience major through biology). Also get some experience working in such a lab and decide if you really like it.
 
How has your work effected the way you live your life (changed your views toward self/others/the universe/etc. & your behaviors)?

Well I probably look at my kids as more of an interesting behavioral experiment than most people. Really it is not my work per se that is important but I do have a very scientific outlook on the world. My wife and I are constantly speculating on the evolutionary significance of various behaviors in kids/friends etc.
 
Is there a clear and precisely defined boarder between Nature and Nurture in the debate by the same name?

No. It is not really a debate in science. There are genetic and environmental influences on most traits and these can be estimated from twin studies. There are some disputes regarding the estimates and proper controls particularly for complex cognitive measures such as IQ. The one interesting finding from most studies is that the primary environmental component is unshared environment. That is, it is not some common environmental condition (eg. parenting strategy) that contributes to the variance between people but events that are unique to the individual.
 
Well neurolinguistics is probably more in a psychology dept. or Cog. Sci.

This is somewhat disappointing, if that's the case I think I'll try double-majoring in neuroscience and linguistics/a specific language. Thanks for the tip :)
 
After getting your PhD, did you become a post-doc before becoming a professor? Does doing so give you a more competitive position in the job market?
 
Well I’m technically an Associate Professor in Cell Biology at TSRI but I was previously in the Neurosciences Dept. at UCSD (and still Adjunct there) and my main focus of study is the Molecular basis of Learning and Memory. Here is a very old web page from UCSD, you can look up newer pubs in medline if interested. Old UCLA lecture here. I also have done some work on general aging mechanisms here. So ask away about science, academic careers, etc. I don’t teach much, mostly graduate lectures. Don’t know undergrad admissions but have been on grad school admission committee.

I dont know what a neuro scientist or whatever you are is cuz im not that smart but I herd of some scientist trying to reverse body aging not just physically on the inside and that we where coded to live and no codes in our body to die just wondering where things like this people come up with, they say in 50 years they can have the technology to prevent much death from ageing related diseases and such u kno i just wanna know where people get crazy ideas and take up on em from and how scientist think we wherent ment to die in codes or w/e in our body..not saying that in specific just wondering in general where scientist get the crazy ideas they come up with and many turn out to work but some like this just seem..rather...insane and like the scientist need to check into a mental hospital

I know for a fact that English and Italian uses slightyl different parts of the brain to each other. They proved that Italian is easier to speak than English.
 
I'm not a neuroscience professor, but I know a few.

How does learning multiple languages affect the brain?
I seem to remember that it matters when you learn the additional language, but I can't currently remember where I saw the data.

Mark is correct in that you really should volunteer in a lab. Volunteering in a lab is the secret to getting a good graduate posting.

There are a whole host of neuroscience courses available for free on iTunes. I highly recommend prelearning as much as possible, since you seem to want to change focuses.
 
[poorly-written waffle]

Scientists get their 'crazy' ideas from asking questions and discovering how things work.
It's quite simple. You ask 'how do we age?'
You look at the differences between aged and young people.
You look at how those differences might occur.
Along the way you develop techniques that interfere with these processes.

You wonder if these techniques can be used on healthy humans.

It doesn't seem crazy to me.

What we know about Wernicke's area and Broca's area is... Surprisingly little, considering how long we've known about them, but it SEEMS that Wernicke's area shows little change in activity regardless of what language you're listening to/reading (in multilingual people) and changes in activity levels when given the stimuli in different ways (sound, written word, though this makes me wonder how it changes between an alphabet and an ideographic system), whereas Broca's area apparently DOES change, but it depends on what you're using. People shifting from using one language commonly to using another more often show an apparent shift in activity and the new language will eventually become second nature if enough time is spent speaking it. It SEEMS TO ME based on what I've seen that there can be different connections in the brain for different languages simultaneously, but the one you use every day is dominant, which would make sense given that changing and learning is what the brain does, but forming new connections or changing old ones can apparently become more difficult as one ages based on some of the data, though by how much and in which areas of the brain isn't entirely certain. These are not the only area's of the brain associated with speech, and they may not even be solitary areas (some suggest they are composed of may different sections with different functions, but I do not know enough to say why they suggest this). If I'm totally wrong here, please correct me :(

When you say change focuses, are you talking about my response to Mark? Regardless, I guess I should find a lab to volunteer in, huh?
 
Sorry, I thought that your undergrad wasn't in neuroscience and you were looking to become a graduate student in neuroscience. To me, I'd think that involves a change in focus. This is why I'd recommend teaching yourself undergrad neuroscience on your own time, because catching up at the graduate level might be tough.

Volunteering has really paid off for a lot of people, if you put the time in.

Oh, no, I haven't even received a bachelor's degree, I've essentially just finished my required "general studies" courses and have yet to declare a major. The problem is that my school has no neuroscience courses, much less a department.

Do you have any tips on how exactly to go about finding a lab and volunteering in it? Are you talking about become an undergrad slave, or is this something I can do without being a student at the university in which the lab is located?
