Know your brain: Meninges

by neurosci in Neuroscientifically Challenged

Where are they?











Close-up view of the meninges surrounding the brain.






The term meninges comes from the Greek for "membrane" and refers to the three membranes that surround the brain and spinal cord. The membrane layers (discussed in detail below) from the outside in are the: dura mater, arachnoid mater, and pia mater. Their positioning around the brain can be seen in the image to the right.What are they and what do they do?The brain is s........ Read more »

Why the new paper by Christakis and Fowler on friendship makes me queasy

by neuroecology in Neuroecology

I am a neuroscientist, and as a neuroscientist I have a strange belief that most of who we are comes from our brains. My entire career is based around understanding behavior from this neural level which I feel to be fairly justifiable. So when I see paper looking at the genetics of behavior, I expect to see at […]... Read more »

FEELING THE HEAT: THE SCIENCE OF SUNBURN

by Amy Swanston in Antisense Science

No matter how careful we are, at some point in all of our lives we will develop sunburn. Despite all of the NHS campaigns and warnings that sun damage can cause skin cancer, many of us will know at least one person who forgoes using suncream and lets themselves bake in the sun in the quest for the perfect summer glow. But what is sunburn? And why is it so dangerous? First we need to take a look at our skin.... Read more »

by Erin Campbell in HighMag Blog

How many times can you say the word “gonad” in a sentence without giggling? If the answer is one, then I congratulate you on turning thirteen. If the answer is many, then you must be a biologist. Biologists appreciate the value of a good gonad, and so should you. The gonad of the worm C. elegans serves as an important model in which to study tissue organization and development, as you’ll see in the paper that accompanies today’s image. At the end of cell division, cytokinesis typical........ Read more »

Quick, Somebody Get The Name Of That Shark!

by Mark E. Lasbury in The 'Scope

There has been a rash of great white shark sightings and attacks in the news recently. But, have attacks and sightings remained constant, or are they really on the increase? Several news studies provide evidence that the Marine Mammal Protection Act of 1972, the ban on commercial whaling in 1982, and the ban on great white hunting in 1997 have increased the number of sharks on the coasts of the North America and Australia. In addition, great white sharks live much longer than previously assumed,........ Read more »

Japanese Encephalitis Virus (JEV), ER stress, and Apoptosis

by thelonevirologist in Virology Tidbits

Japanese Encephalitis Virus (JEV) is a causative agent of acute encephalitis in humans, and being an arthropod borne virus transmitted predominately by mosquitoes ( that primarily target domestic animals and humans, with an estimated mortality of up to 70000 deaths reported per annum. Upon infection the viral proteins localise to the ER where they induce the ER stress which eventually induces Caspase dependent apoptosis.

Physicians face difficult choices when treating patients with bipolar and obsessive compulsive disorders

by Valerie Ashton in The Molecular Scribe

New research suggests patients with both bipolar disorder and obsessive compulsive disorder should receive treatments for bipolar disorder alone. Bipolar and obsessive compulsive disorder therapies taken together can cause worsening of disease symptoms, making it difficult for physicians to treat both conditions. This is a concern as over 1 in 5 patients with bipolar disorder develop obsessive compulsive disorder during their lifetime.... Read more »
