I love interaction and scientific dicussion. Never be afraid to ask me questions. I may not have the answer, but I'll be damned if I haven't learned how to do a good, quick Google Scholar search to find out.
In addition I like to look at non-science related cute animal pictures, art and funny comics too :)
Hope you enjoy my blog but please, feel free to leave suggestions for improvement!
The Ventricular System
I tried to explain to a non bio person that there were ventricles in the brain…didn’t go so well
The development of the human brain
First the embryonic spinal chord is formed along common sequences and patterns then the nervous system develops from a simple elongated neural tubes. The cranial region then differentiates into several clusters of cells which produce the forebrain, midbrain and hindbrain portions.
Nothing gets me hot and bothered like a high encephalization index

clementive replied to your photo “From Neuroscience Research Techniques Do you know about Chiari…”
My answer was “no” and I’m always reading about neurological conditions. Now, I feel the need to dig deeper. Thank you for sharing this :)
Sharing knowledge is my pleasure :)

I see the benefits but, sorry, this is scary as…
No apologies necessary. With every step in advancing biotechnology, there is a huge potential for abuse towards human life. This is why I find bioethics (and frankly ethics in general) to be so important.
Yes, we are getting to the point where we can do more, but should we? Better yet, how should we?
Unless you know someone personally affected by this condition, or conduct research in this area, your answer is likely ‘no.’ But the rate of occurrence of Chiari malformation (CM) is not entirely rare!
We would like to help raise awareness of this neurological condition that is thought to affect 1 in 1000 people, the predominance of whom are females.
In this condition, brain tissue descends into the spinal canal at the base of the skull and can cause any number of symptoms that are often attributed to other sources or simply not properly traced back to the underlying cause. Some people with CM are entirely asymptomatic while others experience a range of severity of symptoms such as headaches, unsteady gait, neck pain, dizziness, vision problems, numbness and tingling of hands and feet or difficulty swallowing, among others.
There are three types of CM that are classified based on the severity of the case and the parts of the brain that protrude from the skull. Causes of CM range from congenital deformations of the skull that form in utero to excessive drainage of lumbar or thoracic spinal fluid that can occur from injury or infection later in life.
So what can be done about CM? In some cases, pain management is all that is required if headaches or pain are the primary symptoms. Other patients with more severe cases must undergo surgery to reduce pressure on the cerebellum and spinal cord and restore the normal flow of spinal fluid.
Here are a few links where you can learn more about CM:

A sensor that measures the amount of active antibodies in the blood stream is paving the way for personalised treatments for bacterial diseases, perhaps spelling the end of the superbug era.
Researchers have developed a new method involving the use of nano-sized levers as sensors to rapidly measure the level of antibiotic molecules in the blood as well as how effective the antibiotic is at dealing with the bacteria. This could pave the way for personalised treatment of bacterial diseases.
“Some of our most effective antibiotics are like termites eating away at the walls of a wooden house – they attack bacterial cell walls so they eventually collapse,” said Professor Matt Cooper, from The University of Queensland’s Institute for Molecular Bioscience.
“But competing molecules in the blood can bind to antibiotics and prevent them from working, meaning there are less molecules free to exert force on bacterial cell walls.
“The sensor we developed, one billionth of a metre in size, can detect the bending that occurs in a cell wall when it is assaulted by antibiotics. The sensor enables us to measure how many antibiotic molecules are free in the blood to attack bacteria and treat the infection based upon how much force they exert onto the wall.”
