Asked in Medical Terminology, Spinal Cord, Brain

What is the medical term meaning membranes surrounding the brain?

The meninges (from the Greek meninx, meaning "membrane") cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer covering the central nervous system. The arachnoid (from the Greek arachne, meaning "spider") is a web-like network of collagen and elastic fibers. The innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural...

What affects the accuracy of memory?

Human memory is an amazing thing, but there are many ways memory can fail. Here is a brief explanation of Daniel Schacter's "seven sins of memory." Three sins of forgetting: Encoding failure from absent-mindedness. If we paid attention to every single detail it would be really overwhelming, so oftentimes certain information never enters our long-term memories and thus we cannot recall it later. Storage decay over time, which is called transience. Oftentimes the memory we have successfully stored is just forgotten later on. This is...

How long does it take to recover from a medically induced coma?

The coma itself, if medically-induced can usually be quickly reversed (in an adult who is otherwise fairly healthy) by giving medication to counteract the drug used (e.g., Narcan for opioid narcotics) or by allowing the drug used to "wear off", since these are usually short acting drugs if not continually given in repeat doses. Depending on the reason for induction, full recovery may require additional treatment for the other conditions present even after the patient is fully brought out of the coma...

Is there any technology to control the brain waves?

There is a technology called brainwave entrainment that uses audio to alter or influence brainwave activity. Basically, you listen to a special audio CD with a pair of stereo headphones. In one channel a particular frequency is introduced, and in the other a slightly different frequency is played. The difference between the two signals is called a beat frequency. The developers say that the brain interprets this beat frequency, and causes brainwave synchronization at the beat frequency between the two hemispheres of the...

What is the function of the medulla oblongata?

The medulla oblongata is the most vital part of the brain because it is the control center for breathing, blood pressure and heart beat among other involuntary body functions not under conscious control.

What is foci of T2 hyperintensity in the subcortical and periventricular white matter?

This phrase is a statement that would be used by a radiologist when reviewing the results from a MRI.

In a T2-weighted scan, areas that are fluid-filled appear bright, while areas that are fatty appear dark. A T1 scan would show the opposite results. Hyperintensity - An indication of a bright region on the scan. Foci of T2 Hyperintensity, therefore, means "focal points, or concise areas,...
