Sleep disturbance following traumatic brain injury (TBI) is a common clinical challenge.Hypersomnia and insomnia can both been seen in the TBI population.The risk factors related to TBI-related sleep disturbance are not well known. Identification of risk factors can provide insight into clinical assessment and management.Lijun Hou and colleagues recently examined risk factors related to subjective sleep complaints in a series of 98 TBI subjects.The study sample include adults admitted to a ........

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. My entire career is based around understanding behavior from this neural level which I feel to be fairly justifiable.

It appears that certain personality traits and traumatic early life events are typically associated with binge drinking in teenage years. However, the predictive power of each type of factors by itself (personality or individual history for example) is not absolute. A new study evaluated not only one single factor, but a series of psychological, genetic, and neurological elements for their ability to determine, when combined, current and future alcohol misuse in a large group of youngsters. ...

Where is it?
Thalamus (in red).
The thalamus is a large, symmetrical (meaning there is one in each hemisphere) structure that makes up most of the mass of the diencephalon. A large number of pathways travel through the thalamus, including all of the sensory pathways other than those devoted to olfaction (smell).What is it and what does it do?The thalamus is often described as a relay station. This is because almost all sensory informati........ Read more »
