NEWBORN NEURONS / ESTABLISHING NETWORKS

ByTeam HUMANITYUAPD

NEWBORN NEURONS As a baby emerges from the womb, brain development expands to include processing responses to the baby’s new experiences sights, sounds, smells, actions, sensations, and emotions. Networks of neurons, primed to receive new stimuli,compete for survival. It’s a random battle at first, but soon becomes more organized as environmental stimuli strengthen some connections…

A GOOD START FOR THE PREGNANT MOTHER

ByTeam HUMANITYUAPD

A good start for the pregnant mother – diet/prevention/risk EAT WELL The first, and easiest, thing a mother to be can do is to eat for two: This doesn’t mean doubling up on servings it means remembering that the vitamins and minerals from a well-balanced diet not only nourish mom’s brain and body but the…

NEW BORN BRAIN – SUPPORT & SURVIVAL

ByTeam HUMANITYUAPD

NEW BORN BRAIN – SUPPORT & SURVIVAL Migrating neurons are helped along by glial cells. They support and nourish the neurons on their journeys. Some help regulate the neurons’ metabolism, and others coat the nerve cells’ axons with myelin, a fatty substance that provides electrical insulation and thus controls the speed of communication along neural…

NEURON & UNDERSTANDING MIGRATION – NEW BRAIN

ByTeam HUMANITYUAPD

NEURON MIGRATION The most dynamic growth occurs in the cerebral cortex, the largest and outermost layer of the brain.During the first months of fetal development, when 250,000 new nerve cells are being created every minute, neurons begin to take on specialized tasks. First, they inch their way from where they were formed by cell division…

A NEW BRAIN FROM THE WOMB TO CHILDHOOD

ByTeam HUMANITYUAPD

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…

SPECIALIZATION BEGINS / GENDER DIFFERENCES / PREPROGRAMMING [ BRAIN DEVELOPMENT ]

ByTeam HUMANITYUAPD

SPECIALIZATION BEGINS As modern humans evolved from their hominid ancestors, their brain development continued with increasing specialization of regions and functions. One hypothesis suggests that the differences between the left and right hemispheres of the human brain can be traced to humans’ simian ancestors swinging through trees. Grasping one limb after another requires the arms…

THE THREE BRAINS – EVOLUTION ( MACLEAN )

ByTeam HUMANITYUAPD

THE THREE BRAINS – EVOLUTION [ MACLEAN ] THE THREE BRAINS Neuroscientist Paul MacLean suggested in 1967 that the human brain functions as three separate “brains,” each of which represents a stage in evolutionary development. He referred to the three-way unity as humanity’s triune brain. Through evolution’s penchant for preserving genetic code that proves useful…

EVOLUTION – GROWING COMPLEXITY [ BRAIN DEVELOPMENT ]

ByTeam HUMANITYUAPD

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…

DIABETES INSIPIDUS / DIEBETES MELLITUS [ CLASSIFICATIONS ]

ByTeam HUMANITYUAPD

DIABETES INSIPIDUS / DIEBETES MELLITUS [ CLASSIFICATIONS ] – NERVOUS SYSTEM DIABETES INSIPIDUS When the nervous and endocrine systems get out of balance, the resulting dearth or overabundance of hormones can cause havoc. Consider just one hormone. The pituitary gland in the brain stores antidiuretic hormone (ADH), also called vasopressin, which is created by the…

THE ENDOCRINE SYSTEM [ THE NERVOUS SYSTEM ]

ByTeam HUMANITYUAPD

THE ENDOCRINE SYSTEM  The nervous system isn’t the only method by which the brain controls the body and maintains homeostasis. The direct, electrochemical means by which the nervous system collects information from stimuli and then formulates responses is augmented by the endocrine system, which works with the nervous system to regulate the body’s cells. The…
