P L A N T - R O S E M A R Y (Rosmarinus officinalis)

Rosemary, Rosmarinus officinalis, is a woody, perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple or blue flowers, native to the Mediterranean region. It is a member of the mint family Lamiaceae, which includes many other herbs, and is one of two species in the genus Rosmarinus. The name "rosemary" derives from the Latin name rosmarinus, derived from "dew" (ros) and "sea" (marinus), or "dew of the sea"[2] because in many locations it needs no water other than the humidity carried by the sea breeze to live. The plant is also sometimes called Anthos, from the ancient Greek word ἄνθος, meaning "flower".[3]
Rosemary is used as a decorative plant in gardens and has many culinary and medical uses. The plant is said to improve the memory and is used as a symbol of remembrance, especially in Australia and New Zealand to commemorate ANZAC Day. The leaves are used to flavor various foods, like stuffings and roast meats. Rosemary contains the antioxidants carnosic acid and rosmarinic acid, and other bioactive compounds including camphor, caffeic acid, ursolic acid, betulinic acid, rosmaridiphenol, and rosmanol. Some of these may be useful in preventing or treating cancers, strokes and Alzheimer's Disease.

Whether we are mentally active, resting or asleep, the brain always has some level of electrical activity. The study monitored the frequency and location of electrical brain waves through the use of EEG (electroencephalography). EEG headset are placed in standard locations of the head.

The fundamental unit of the brain is termed a neuron - this is just the scientific term for a single brain cell. A neuron communicates to other neurons via electrical impulses, also called potentials, and chemical secretions called neurotransmitters, whose effect is not perfectly understood. Electrical input to one neuron comes from many others, each having a specific amount of influence, or weight, on the neuron.

These electrical waves that our brain produces, by the help of EEG headset turn into images or can even be used to produce music.

This machine is very complex. It is used widely in medicine, psychological studies and even in arts.
