Brain-based intelligence tests are concerned with both of these aspects. Modern techniques have evolved to focus on a few biological characteristics: Brain ERPs, brain size, and speed of neural conduction. Various instruments have been employed to measure these things.
Pam Reynolds Lowery (1956 – May 22, 2010), from Atlanta, Georgia, was an American singer-songwriter. [1] In 1991, at the age of 35, she stated that she had a near-death experience (NDE) during a brain operation performed by Robert F. Spetzler at the Barrow Neurological Institute in Phoenix, Arizona.
The CT scan was introduced in the 1970s and quickly became one of the most widely used methods of imaging. A CT scan can be performed in under a second and produce rapid results for clinicians, with its ease of use leading to an increase in CT scans performed in the United States from 3 million in 1980 to 62 million in 2007.
Brain implants or neuromodulation (using electrical currents to alter brain activity) could represent the next wave of treatments, Schnakers said. She emphasized the need to provide families with ...
Your brain accounts for only about 2% of your body weight, but it uses roughly 20% of your body’s total energy. Even when you’re sleeping , your brain is burning tons of energy just to keep ...
A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...
The rate of CSF formation in humans is about 0.3–0.4 ml per minute and the total CSF volume is 90–150 ml in adults. [ 2 ] Traditionally, CSF was evaluated mainly using invasive procedures such as lumbar puncture, myelographies, radioisotope studies, and intracranial pressure monitoring.
Cranial ultrasound is a technique for scanning the brain using high-frequency sound waves. It is used almost exclusively in babies because their fontanelle (the soft spot on the skull) provides an "acoustic window". A different form of ultrasound-based brain scanning, transcranial Doppler, can be used in any age group.
