WAVES OF CHANGES – AN ADOLESCENT BRAIN

WAVES OF CHANGES – AN ADOLESCENT BRAIN As CHILDREN become teens, the brain continues to develop, grow, and change along with the rest of their body. Brain specialization becomes more apparent at adolescence. The adolescent brain can imagine and ponder at a much higher level than a child’s brain. Whereas a child tends to dwell…

LEARNING LANGUAGE [ BRAIN DEVELOPMENT ]

LEARNING LANGUAGE [ BRAIN DEVELOPMENT ] The enhancement and pruning of neural networks occurs most apparently as the baby begins to develop language. Spoken languages can sound very different from each other. In all, human languages produce about 200 different spoken sounds, called phonemes. Spoken English contains just over one-sixth of those possible sounds. Brain…

A NEW BRAIN FROM THE WOMB TO CHILDHOOD

A NEW BRAIN FROM THE WOMB TO CHILDHOOD WHEN SPERM meets egg, the merger of a father’s and mother’s DNA triggers the start of a new life. Encoded in the tens of thousands of genes that make up a human being are a substantial fraction that will create the brain and central nervous system. You…

EVOLUTIONARY CULES OR PAVLOV’S DOGS

EVOLUTIONARY CLUES OR PAVLOV’S DOGS EVOLUTIONARY CLUES Some of humanity’s evolutionary history can be observed in the development of a human fetus. As chicken and human embryos develop, for example, they experience a stage where they both have a tail, as well as arches and slits in their neck remarkably like the gill slits and…

EVOLUTION – GROWING COMPLEXITY [ BRAIN DEVELOPMENT ]

EVOLUTION – GROWING COMPLEXITY [ BRAIN DEVELOPMENT ] GROWING COMPLEXITY If 2,000 neurons are sufficient for simple learning, imagine the explosion of complex behavior that accompanied the growth of neural complexity about 530 million years ago. Larger clumps of neurons in the diverse animal population that seemingly emerged overnight encouraged the flourishing of new animal…

BRAIN DEVELOPMENT – EVOLUTION [ GROWTH & ADAPTATION OF THE HUMAN BRAIN ]

BRAIN DEVELOPMENT – EVOLUTION [ GROWTH & ADAPTATION OF THE HUMAN BRAIN ] FROM THE single celled product of conception, the human animal grows into a complex, uniquely cognitive being. Evolution has built upon older, more primitive animal brain forms to lead humanity to emotion and rational thought. Over eons of time, neural circuitry has…
