The most efficient model for understanding the brain in terms of its evolutionary history is the triune brain theory developed by Paul MacLean. According to this theory, humans actually have three brains inside the skull.
- The reptilian brain is the oldest of the three brains and it controls the body’s vital functions such as heart rate, breathing, body temperature, instincts and balance. Our reptilian brain replicates the main structures found in a reptile’s brain: the brainstem and the cerebellum. The reptilian brain is rigid and highly compulsive and cannot be changed.
- The limbic brain emerged in the first mammals. It records good and bad memories and experiences and it is responsible for emotions and value judgements. The main structures of the limbic brain are the hippocampus, the amygdala, and the hypothalamus. The limbic brain unconsciously exerts a strong influence on human behaviour and it can cause a shift in consciousness towards irrational behaviour.
- The neocortex is the new brain which contains two hemispheres responsible for the development of human language, abstract thought, imagination, and consciousness. The neocortex is flexible and is believed to have almost infinite learning abilities and has contributed to the development of art and culture.
Around the world Western populations are bringing colour into their environments. Colour lifts the spirits and aids the healing of depression.
The Junk Castle is an amazing building constructed by high school teacher Vic Moore for his Master of Fine Arts thesis in 1970, it’s made from material collected at the county dump, including washing machine parts, dryer doors, bedsteads, and the door of a 1952 Oldsmobile.
