Seizures and the Nervous System

ByTeam HUMANITYUAPD November 9, 2022August 8, 2024

Introduction to Seizures and the Nervous System Seizures are complex neurological events characterized by sudden, uncontrolled electrical disturbances in the brain. Understanding seizures requires a fundamental grasp of the nervous system’s anatomy and function. The nervous system, composed of the brain, spinal cord, and a vast network of neurons, serves as the body’s communication infrastructure,…

MIGRAINES [ THE BRAIN’S EQUILIBRIUM ]

ByTeam HUMANITYUAPD November 7, 2022November 7, 2022

MIGRAINES [ THE BRAIN’S EQUILIBRIUM ] THE DAMAGE caused by headaches is eye-popping. About 45 million Americans suffer them regularly, and about half of the sufferers find the pain severe and sometimes disabling. The result: lost time from work, play, the day to day stuff of life. Counting only the 30 million who suffer migraine…

DELICATE BALANCE – THE BRAIN’S EQUILIBRIUM [ HOMEOSTASIS ]

ByTeam HUMANITYUAPD November 4, 2022November 4, 2022

DELICATE BALANCE – THE BRAIN’S EQUILIBRIUM [ HOMEOSTASIS ] THANKS TO THE autonomic nervous system, the human body pretty much takes care of itself without conscious effort. The weather changes but core temperature is maintained, food gets digested, cycles of sleeping and waking follow upon one another, and the body’s status remains fairly even from…

THE NERVOUS SYSTEM [ WORKING TOGETHER/SEEING THE BALL ( WHAT IS PLEASURE? ) ]

ByTeam HUMANITYUAPD November 1, 2022November 1, 2022

THE NERVOUS SYSTEM [ WORKING TOGETHER/SEEING THE BALL ( WHAT IS PLEASURE? )] WORKING TOGETHER How do all of these systems central and peripheral, somatic and autonomic and receptors work together in the symphony of the brain? From simple actions to complex ones, these systems must work in concert. Consider the “simple” act of catching…

GOOD FEELINGS / PLEASURE CENTERS [ NERVOUS SYSTEM ] GOOD FEELINGS Pleasure also has its centers In the brain. A Tulane University neurologist stumbled across one such center in the 1950s when he tried to electrically stimulate the brains of schizophrenics to break them out of their passivity. His patients told him their implanted electrodes…

BIG PAIN [ MESSENGERS ( THE NERVOUS SYSTEM ) ]

ByTeam HUMANITYUAPD October 28, 2022October 28, 2022

BIG PAIN [ MESSENGERS ( THE NERVOUS SYSTEM ) ] It turns out, the brain has automatic defenses cued up for a quick response to more serious pain. The perception of pain warns the brain of actual or potential tissue damage. The brain’s recognition of pain sets in motion actions to reduce or remove it,…

PAIN GATEWAY [ MESSENGERS ( THE NERVOUS SYSTEM ) ]

ByTeam HUMANITYUAPD October 27, 2022July 5, 2023

PAIN GATEWAY [ MESSENGERS ( THE NERVOUS SYSTEM ) ] The nervous system does have natural responses that can ease minor pains, like the sting of a scrape or ache of a bump. When you were a child and trying to learn to roller-skate, perhaps you once fell and skinned your knee. To stop your…

SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ]

ByTeam HUMANITYUAPD October 23, 2022October 23, 2022

SHOCK TO THE SYSTEMS [ THE NERVOUS SYSTEM ( HARMONY ) ] When you’re startled, the two branches work together, regulating the body without any conscious thought needing to be involved. Thanks to these automatic responses, the brain’s cortex is allowed to remain free to do other things-process sensory information, register emotion, pursue rational thoughts,…

THE AUTONOMIC NERVOUS SYSTEM / TWO BRANCHES

ByTeam HUMANITYUAPD October 22, 2022July 5, 2023

THE AUTONOMIC NERVOUS SYSTEM / TWO BRANCHES THE AUTONOMIC NERVOUS SYSTEM Much of what the brain does takes place beyond our ability to sense it-or appreciate it. In the midbrain’s pons and medulla lie the centers that regulate the vital, everyday functions of life. Think about it: How fortunate you are that you don’t have…

THE CEREBRAL CORTEX [ HARMONY ( THE NERVOUS SYSTEM ) ]

ByTeam HUMANITYUAPD October 22, 2022July 5, 2023

THE CEREBRAL CORTEX [ HARMONY ( THE NERVOUS SYSTEM ) ] THE CEREBRAL CORTEX Seven-tenths of the volume of the human nervous system lies in the cerebral cortex. Given that the human cortex is many times larger than that of any other creature, scientists are convinced its huge size is the main source of what…
