electroencephalogram

Definition

A medical test that measures and records the electrical activity of the brain using electrodes placed on the scalp; abbreviated as EEG. It is used to diagnose neurological conditions such as epilepsy, sleep disorders, and brain injuries.

Example Usage

The neurologist ordered an electroencephalogram to investigate the patient's recurrent seizures.

Origin

From Greek 'elektron' (amber, electricity), 'enkephalos' (brain), and 'gramma' (recording or writing).

Fun Fact

The first human EEG was recorded in 1924 by German psychiatrist Hans Berger, revolutionizing neurology and brain research.

speciation

The evolutionary process by which new species emerge, usually when populations get separated long enough to develop incompatible dating preferences. This biological phenomenon explains why Darwin's finches have different beaks and why your family reunions get weirder the more distant the relatives. In chemistry, it's about determining which molecular species are present, which is somehow less dramatic.
