As a “World Cup tie in post” this one’s a bit late, but here’s a story that’s been getting a lot of attention: According to scientists, Neymar uses instinct and not his brain when playing football Yes, if you believe the headlines, research has shown that legendary Brazilian forward Neymar da Silva Santos is so […]The post Functional Neuroimaging’s Neymar Problem appeared first on Neuroskeptic....

Anecdotal reports have linked traumatic brain injury with later violent death including death by suicide.Few large epidemiological studies have been published on this association.However, a recent Swedish population study published in JAMA Psychiatry provides valuable insight into this issue.Seena Fazel and colleagues from the University of Oxford, University College London and the Karolinksa Institute examined a large database of over 200,000 patients with TBI.Cases of TBI were identified from ........

(Attention warning: massive speculation ahead.) Auguries often seem made up, useless. Is that why they are useful? Dove figured that the birds must be serving as some kind of ecological indicator.

Sleep problems are common following traumatic brain injury (TBI).In a previous post, I reviewed a study of the risk factors for sleep disorders following TBI.The most severe TBI is a risk factor for hypersomnia. Anxiety and depression following TBI increase risk for insomnia complaints.Few large studies of treatment for sleep problems after TBI exist. However, a recent manuscript outlined the potential benefit of treatment of sleep disorders in a series of 12 subjects.Catherine Wiseman-Hake........ Read more »

Okay, not quite all of them. But it looks like Misha Ahrens and Jeremy Freeman are going to continue their reign of terror, imaging the whole zebrafish brain as if it’s no big deal.

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 »

I am a neuroscientist, and as a neuroscientist I have a strange belief that most of who we are comes from our brains.
