-
Quantitative electroencephalogram (QEEG)
A type of “brain mapping” test that analyzes the electrical activity of the brain to measure and display patterns for diagnostic information.
-
Programmed cell death (also known as apoptosis
The death of cells, which occurs as a controlled part of a biological process.
-
Prefrontal cortex (frontal lobe)
The part of the brain that determines what you pay attention to and how you respond to it.
-
Polyunsaturated fat
A type of good dietary fat that includes omega fatty acids and is often found in seeds and grains. A triglyceride in which the fatty acids have two or more points of unsaturation.

-
Polyphenol antioxidants (also known as polyphenols)
Micronutrients that supply a highly protective shield for the brain, keeping neurons in peak condition by preventing inflammation and oxidation and even improving the way neurons communicate and grow.
-
Nutrient density
The ratio of micronutrients per calorie in food. A way of expressing the nutrient content of a food or diet relative to the energy yield (i.e. /lOOOkcal or /MJ) rather than per unit weight. The ratio of calories to other nutrients in food. The nutrient composition of food expressed in terms of nutrient quantity per…

Neurotoxin
A substance that destroys nerve tissue. A substance that is poisonous or destructive to nerve tissue. Toxin, found in the venom of certain snakes, in some fish, shellfish, and bacteria, and in certain other organisms, that is toxic to nervous tissue. A substance that damages nerve tissue. The principal effects of a neurotoxin are paralysis,…
-
Neuroprotective
Referring to actions or nutrients that tend to protect nerve cells from damage or degeneration. An agent that protects or prevents damage to the nerves. Providing a certain level of safeguard to the nervous system against potential harm or injury.
-
Neurofeedback
A type of biofeedback where brainwave activity is monitored through real-time digital tracking and regulated or reorganized through sound or visual signals to improve brain function.
-
Neural adenosine triphosphate (ATP)
A central metabolite that serves as the main source of energy for most cellular processes.
