Do scallops have a brain? Is it okay for vegitarians to hunt them?
Alright my family is planning another "scalloping" trip. Basically you go snorkling and pick them up. Would it be okay for me to take part in this as a vegitarian? Why or why not?
Do they feel pain? Have a brain? Love? Scientifically why would it be okay or not okay to hunt them?
Okay for one thing, I would still be socializing with my oh so fabulous family. that has nothing to do with it, this is strictly about whether i would be taking part in the actual hunting on the scallops.
----------
No, scallops don't have a brain per se. They have a nervous system that is much more primitive than ours. They probably perceive things like pain as just something to avoid rather than something that "hurts" if that makes any sense. They certainly don't love or reason or anything else that mammals might do. So, go ahead and enjoy your trip with your family. Just make sure you're doing it in an environmentally friendly manner and that the population of scallops isn't threatened. (

Is brain swelling normal after a major stroke and how long before we should worry?
My ex husband had a stroke three days ago and now his brain is swelling, they cannot treat his stroke (Ischemic) because of blood disorder problems. They say to just sit and wait. He already has 70 % damage to the right side of his brain. He is still awake and gives one word answers. He is 42 years old. I just dont know what to say to prepare my child for this. He is 9 years old.
----------
The hospital where your husband is will have a chaplain and a "child life specialist", and I encourage you to avail yourself of both.
Ask the doctor to write an order for your son to see the child life specialist. She (usually) will be highly experienced in working with kids who are in scary situations in hospitals and will be able to explain what's happening to your husband in a way your son will be able to understand.
If there's a way you can have the chaplain with you when the neurologist makes rounds, it will be great support for you and may soften the blow when the doctor tells you about your husband's prognosis for a functional recovery. 70% damage is huge.
Ask the doctor for referrals for speech, occupational, and physical therapies if he hasn't already.
I'm sure the neurologist will (

I take seizure medication after having brain surgery that removed a malignant tumor. I am suppose to have a?
I am suppoes to have a brain scan every year to see if any of the tumor has recurred. I have decided to not have anymore brain scans for reasons that is too much to explain on this site.
My question is this, because i don't want anymore brain scans can that cause a doctor to no longer renew my seizure medication prescription. I still would like to get the seizure medication, i'm just wondering if the brain scans is connected to the seizure medication?
----------
Your doctor can stop your medication refills, but I don't see why he would right away. For what ever reason you decided to cut the yearly scan, you should consider scans every other year. Discuss with your doctor that you would still like to continue the medication. But if you don't need the medicine, you shouldn't be taking it. Seizure meds , especially Dilantin, have a boat load of yucky side effects. The brain scans are really essential in detecting if cancer is returning. If your scan appears clear, then the meds might be discontinued. the meds were given to you after surgery because surgery is tramatic and stressful to the body, and the stress from that alone can cause a seizure.

Is there a correlation between brain tumors and antidepressants?
I've always been against antidepressants use for long periods of time. I don't have a problem with people using them for some time. But when it becomes something that you have to keep taking for the rest of your life, that's when I ask: what are the long term effects of antidepressants? Is there a correlation between brain tumors and antidepressants?
I seek intelligent answers only.
Thank you.
----------
I have never heard of brain tumours as a result of long term anti-depressant use. The newer anti-depressants (SSRI's) Help the person keep their own serotonin. If someone needs to take them forever then so be it. (

What to expect in the final stages of metastasis lung and brain cancer?
I am 37 years old. I had breast cancer 4 years ago. Six months ago i found out i have metastasis lung and brain cancer. I had one large tumor removed from my brain. But still have lots of small tumors scattered in my brain they cannot remove. I want to know what i will expect in my final months or weeks. I have short memory loss, slight headaches, nausea and tiredness at the moment. Will i get to the stage of not been able to move, speak, see, hear etc?

What is the chemical your brain releases when your injured?
I am not talking about adrenaline or endorphins, atleast I don't think I am. Adrenaline pumps you up and endorphins make you feel good. I'm talking about when you just tried to do a trick on your skateboard and you fall and rip up half of your face and your brain releases this chemical that numbs everything. I believe it produces a high as well.
----------
I do believe it is adrenaline (Epinephrine) that keeps your body from feeling pain when initially injured. It stimulates the Sypathetic Nervous System, which is the part of your brain responsible for the sensation of pain, so there must be a link there! (

What are some behavior changes when a traumatic brain injury occurs?
Hi! Im writing an essay how brain injuries can effect the three parts of the brain.
What behavioral changes happens when injury occurs in the:
forebrain
hindbrain
midbrain
If you have links ill greatly appreciate it.
----------
Well then you'll need to do some research on the subject. Problems with the frontal Cortex I think has to do with impulse control. There are some videos on Youtube that may help out if you're too lazy to do you own research. The right brain controls your left side and your left brain controls your right side. BTW I am brain injured. I was able to find brain injury links, and some of them say you aren't allowed on them for research purposes cause jerks go there to harrass these disabled people. (

What can happen to the brain if one has a rather large intramedullary spinal cord tumor?
An intramedullary spinal cord tumor is a tumor inside the cord. So what could happen if a tumor was found inside a person's spinal cord in the cervical region, which is in the neck? What could this possibly do to the brain, specifically? Keep in mind this tumor is long and large enough it expands the cord and been left untreated years.
----------
I hope you are not the patient. The cord tumor can cause increased intracranial pressure- papilledema, sometimes acute enough to cause other symptoms, like vomiting, headache. Not very common, but I have seen a couple.
Understand that we never see anything common at Walter Reed- the other hospitals can handle the common stuff. So sometimes it is hard to get a good idea of just how common a given problem is.
Usually the symptoms of a cord tumor are related to the damage to the spinal cord.- pain is common, weakness, spasticity, sensory loss muscle wasting in the muscles supplied by the affected part of the cord. A tract of the Trigeminal nerve goes down into the upper cord, then back up- can cause numbness of the face. This can be a confusion factor, as it can be mistaken for a second lesion, and lead to a diagnosis of MS.

What functions does the left side of the human brain control?
My son was born premature and had to stay in the nicu for about 2 months. When he was about a week or two old the doctors informed us that he had a grade 4 bleed in the left side of his brain.He never had any swelling, and it eventually went away. He is now 5 months old, and has hit his developemental milestones for his corrected age (2 months) and some for his actual age. I'm just wondering what kind of damage the bleed could have done, and what functions the left side of the brain controls?
----------
The left side of the brain controls the right side of the body but your son might not have any permanent damage from the bleeding. Children that young are very resilient and the brain has a way of healing itself and/or switching a function of one part to another. At this early age about all you can do is wait and see and have his doctors keep a close eye on his development. (

What is going on in the brain that causes bipolar disorder?
I know it's genetic and all, but can anyone tell me what is going on with the brain specifically?
----------
Yes, it is true that bipolar can be geneticaly related but, it can also be caused as a result of a traumatic event or a brain injury. And geneticaly speaking: their is a 5% chance of having bipolar illness if either the father or the mother suffers from bipolar illness...10% if it is a brother or a sister that suffers from it...14% if either the father or the mother/ and an uncle or an aunt has it...and 30% if both parents suffer from bipolar illness (witch is very rare).
To answer your question, anatomically speaking (what happens in the brain):
All information that "circulates" through the brain is by neurotransmitters. The "action" basically is an electrical signal (nerve impulse) that is transmitted from the synaptic bulb to the post-synaptic neuron. In simpler terms, their is a "gap" between both sides (the bulb and the neuron) and an electrical impulse "jumps" from one side to the other in order to make the connection and therefor, permits the information to circulate.
The specific region in the brain that regulates emotions and behavioral patterns is the hypothalamus. This region (by releasing different hormones) regulates feelings of rage, aggression, pain and pleasure, and the behavioral patterns related to sexual arousal. The hypothalamus is not only responsible of regulating emotions and behavior. It also acts on the regulation of eating and drinking, controls the body temperature and establishes patterns of sleep and many many more body activities.
Now when someone suffers from the bipolar illness, their are two possibilities:
The first theory is that the "electrical signal" (nerve impulse) will slow down (witch causes the depression phase). And at other times, it will speed up (witch causes the manic phases).
The second theory is that the receptors (the post-synaptic neuron) of the "electrical signal" will become "over-sensitive" (causing mania) or, will simply have a slow reception (causing depression).
That is why when a manic phase is happening, the person feels like their thoughts are racing, they have hyper-activity, are overly happy, suffer from insomnia, etc. And when the depression phase is happening, the person will be filled with feelings of sadness, loss of energy levels, feels like sleeping all the time, have a hard time concentrating and taking decisions, etc. People living with the bipolar illness often refere to living a "roller coaster" of emotions (ups and downs). And in either one of these possibilities, these "mood swings" are not dictated by events and cannot be controled by the person suffering from the illness.
Now these two possibilities are theories because science is unable to specificaly determine witch or what is going on. No blood test, no x-rays, no scans can give the precise answer. Doctors would need to dissect and examine a "live" brain (witch can't be done for obvious reasons...the person would die!!) But doctors have identified these two possibilities of brain "malfunction" causing the bipolar illness. In either cases, the result is that their is an "imbalance" created that causes an emotional/behavioral/mood swing. (witch is why medication is needed to balance/stabelize the emotions/moods.)
Recently, doctors have discovered a way to see if the brain is "malfunctionning" through what is called a SPECT scan. I will add a web site that I have found online that will inform you better on what exactly is a SPECT scan. Some specialist still don't recognise its efficiency because, the scan can determine if their is a "malfuntion" in the brain, but it is still unable to pin-point what effect/illness it causes.
For instance, I had my SPECT scan in 2006 and it showed that I had a "malfunction" and that this "malfunction" is found in people suffering from either: unipolar depression, certain bipolar illness (in the depressive phase), or chronic fatique syndrome. Although for me, it helped alot cause my doctors where able to confirm (with my symptoms) that I was suffering from bipolar type 2 ( I rarely have "hypo-manias" phases and more depressive phases. And my moods are not "extreme" like people suffering from bipolar type 1).
** PS: hypo-mania is a less severe case of mania where the person feel a bit happier (but not exstatic), has a bit more energy and is more productive. It is sometimes not noticed by doctors therefor often causes misdiagnosis...
So, I hope I helped and that my response (even though it is long!!LOL)answered your question properly...And remember the basic thing: people suffering from mental illnesses aren't stupid unlike many people think ;)
Good luck and keep strong :D (
