The pineal gland is a neuroendocrine organ located in the midline of the brain. Melatonin, thought to be the output hormone of the pineal gland, plays a central role in the co-ordination of circadian rhythms and the circadian system. Circadian rhythms are centrally co-ordinated and physiological, psychological and behavioural processes, which in humans follow approximately a 24- to 25-hour alternating cycle. In humans, circadian rhythms are genetically programmed to synchronise with night and day.
amiibo (Japanese: ã¢ãã¼ã amiibo) are a line of interactive figures and cards by Nintendo. Each amiibo figure or card contains an NFC chip in its base, which allows it to interact with multiple games on both the Wii U and New Nintendo 3DS consoles using near field communication. PokÃ©mon amiibo are the franchise's second venture into NFC collectibles, following 2013's PokÃ©mon Rumble U NFC Figures.
They can evolve as they are used in games and as new data is saved. An example is a player can bring their figure to a friend's house and bring their custom, trained character into their friend's Super Smash Bros. game to fight against or alongside with. Note that while amiibos can unlock features in multiple games, an amiibo can only store one game's data. So an amiibo used in Smash Bros. can't also be used to store data for Mario Party 10. Data can be erased, however, to switch an amiibo from one game to the other.
