A Workman's Comp Case-final diagnosis-traumatic brain injury- what kind of a settlement do you think?

  • You would need to consult a lawyer to determine potential settlement. Some lawyers give free case evaluations:

  • In the UK - how the brain injury is caused is largely irrelevant for the purpose of how much compensation you can claim. The example you have given is for an accident at work - so long as your employer is legally at fault a medical report is necessary describing the exact nature of your injuries. Based upon this your solicitor could value the pain and suffering and calculate any additional financial losses to calculate your overall compensation settlement. Please see the related link "brain / head injury claims" to see examples of compensation amounts you could claim with an explanation as to how to calculate your own compensation amount.

How is a brain biopsy done?

How does a jellyfish know what they are doing with no brain?

Essentially, we would presume that a jellyfish would not know or think about what it's doing. A jellyfish would go on its instincts. You have to remember that a jellyfish still has neurons, but it will not have a center of control of these neurons (which we call the brain). Thus, the jellyfish would not think to attack another fish and eat it, its neurons will simply react to the closeness of a fish and engage the jellyfish in this behaviour of killing and eating its pray. It is done pretty automatically.

However, I do not know if the jellyfish would be able to learn with no brain. It can adapt to the environment, but can we make it learn specific behaviours??

So basically jellyfish are like robots, they run on autopilot.

What is the clock speed of the human brain?

It's hard to give a meaningful answer to this, since the brain is more like a massively-parallel analog computer than a digital computer.

Chris Westbury says our "raw clock speed" is 20 million billion calculations per second, or 20,000,000 GHz, yet we can only do conscious calculations at 2 Hz. Individual neurons fire at about 200 Hz max.

Neurons transmit electrochemical signals at about 150 m/s, but digital computers transmit them at close to the speed of light, 300,000,000 m/s.

There are 4 basic levels of brain waves measured on an EEG. They range from about 4 Hz (cycles per second) in deep sleep to over 13 Hz when wake and alert. These have nothing to do with the processing speed of the brain, though, they are more like overall rhythms of the brain.

What is wrong if your bathroom has a sewer smell that's stronger in the evenings and sometimes there is a day or so you really don't smell it but most days you do and you live on a second floor?

Sounds like an "open" connection to the sewer pipes to me. First You have to locate where the smell really is comming from. I.e. the sink (just snif above the sink) or any other hole. Ones you have located the smell you know where to look at. First take a view at the pipes underneath this hole (i.e. under the sink) there has to be a special pipe looks like a nignty-degrees angled "S" if this is not installed have it installed. After this is installed the water in this "S" will block the sewersmell. If it IS installed, clean it by unscrewing it. By the way this is how it is done in The Netherlands. :-) So locally it could be different. Else ask your local plummer.

What could be wrong if you have severe navel pain and bleeding?

Why does brain coral look like a human brain I'd like to know if its possible that humans actually evolved from coral?

No. Humans evolved from a common ancestor we have with today's "great" apes (chimpanzees, orangutans, gorillas). This is proven specifically for human evolution by ERVs and the fused chromosome #2.

Brain coral is just an example of Pareidolia... the phenomena of the human mind to see patterns in things that aren't really anything (like religious images in toast, faces in mountain sides, etc).

Why do feet smell?

Feet can smell due to the accumulation of sweat and bacteria on the skin, creating an environment for odor-causing microbes to thrive. The combination of sweat and bacteria can lead to the production of unpleasant-smelling compounds. Proper foot hygiene, wearing breathable footwear, and using odor-controlling products can help reduce foot odor.
