Ask a (pending) neuroscientist
 

 
Hello all. I'm a neuroscience phd candidate and have noticed a lack of posting in this section. Since many people are curious with regards to how the brain works I thought it ,iChat generate posts here. So to procrastinate during finals week and to liven this section up. ill answer any questions to the best of my ability.

I've been studying a lot of neuroscience lately, mostly about the autonomic nervous system and how it plays into our stress and anxiety that some of us suffer from. I've had IBS and social/general anxiety disorder since I was very young, early elementary school age to be exact. From what I can understand, these can be attributed to overactive sympathetic nervous system functions as well as chronically elevated stress levels.

My question is, what sort of medical treatments, drugs, and therapies can help with these problems? I have medications that treat some of the symptoms, but are there any drugs or therapies that exist that actually treat the cause of these problems? If this isn't really your area of expertise, I understand. Thank you.

Most basic question you'll probably get and I don't even know if it has anything to do with neuroscience....I get headaches 4-5 times a week. What could be some of the reasons why this happens?

SSRIs and Benzodiazapine are common therapies that are used to treat social anxiety; I should know, have it myself. SSRI stands selective serotonin re-uptake inhibiter. Serotonin is an excitaory monoamine which is transfered from cell to cell in circuits that processes emotional information. By inhibiting its re-uptake you are allowing the molecule to stay in contact with the cell for a long period of time. Why does this work? I don't know. I'm not a clinician. Benzodiazipine act on GABA receptors, which in contract to serotonin, allow influx of inhibtiory molecules (it prevents the cell from firing). These drugs bind on these receptors and allow chloride ions to penetrate the cell, thus keeping it from firing. This is how the 'overractivity' you mentioned is countered.

I can tell you what is this physiological reason for headaches in general but I can't tell you why you have chronic headaches.

Usually issues like this are psychological and if you've been diagnosed then you've already been through therapy or seen someone. What were the results of your previous treatment?
Never needed therapy, meds specifically for the IBS help some. The SSRI that I'm on helps with the GAD as well. From what I can tell, my maternal family has a history of high blood pressure and chronic stress (overactive norepinephrine levels?), which would lead me to believe that most of it actually isn't psychological, since I had a decent childhood when these issues first began to take place. Western diet, maybe? Or a majority of it could possibly be genetics, from the trends I'm noticing.

Thanks for the breakdown. I've actually found L-Theanine to help a good deal with acute anxiety, especially for relaxation before bedtime. It's supposed to be non-drowsy but if I take it during the day it calms me down so much that I actually get a great urge to sleep.

What do you think about memories? Do you think information can be placed and erased in someones mind? And what do you think about mind control devices?

Memory is my speciality. Yes information can be placed in and later release by injecting a peptide inhibiter. Mind control devices?

THC imparirs short term memory. THC binds to endocanbinoid receptors which inhibits the production of cyclic adenosine monophosphate (cAMP) which is responsible for modulatating proteins that are activated during the formation of a short term memory.

It's the repeated contraction and dilation of blood vessels.

What chemical stimuli/reaction would result in a destructive inner critic/diminished self confidence?

On what level is inducing small seizures, as in through ingesting hallucinogens (mushrooms, etc) more helpful than harmful for the brain?
1- This usually due to a lack of dopamine or serotonin.
2- It's never helpful.
