cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell.
circuit: A network that transmits electrical signals. In the body, nerve cells create circuits that relay electrical signals to the brain. In electronics, wires typically route those signals to activate some mechanical, computational or other function.
concussion: Temporary unconsciousness, or headache, dizziness or forgetfulness due to a severe blow to the head.
data: Facts and/or statistics collected together for analysis but not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), those data typically are numbers stored in a binary code, portrayed as strings of zeros and ones.
diet: (n.) The foods and liquids ingested by an animal to provide the nutrition it needs to grow and maintain health. Sometimes this is a specific food-intake plan.
factor: Something that plays a role in a particular condition or event; a contributor.
focus: (in behavior) To look or concentrate intently on some particular point or thing.
hippocampus: (pl. hippocampi) A seahorse-shaped region of the brain. It is thought to be the center of emotion, memory and the involuntary nervous system.
information: (as opposed to data) Facts provided or trends learned about something or someone, often as a result of studying data.
link: A connection between two people or things.
marijuana: A mind-altering drug. It is made from the leaves (and sometimes stems or seeds) of the Cannabis sativa plant. This drug also goes by the colloquial terms pot and weed.
maximize: (in psychology) A strategy that some people employ in which they consider every possible option to find the best one. The alternative involves looking at just enough options to find one that is good enough.
neuron: The main cell type of the nervous system — the brain, spinal column and nerves. These specialized cells transmit information by producing, receiving and conducting electrical signals. Neurons also can transmit signals to other cells with chemical messengers.
nutrient: A vitamin, mineral, fat, carbohydrate or protein that a plant, animal or other organism requires as part of its food in order to survive.
recall: To remember.
synapse: The junction between neurons that transmits chemical and electrical signals.
