Chapter 3 Physiology of the Brain/ Chapter 5 Conciousness Flashcards
What are the 3 major sections of the brain
Forebrain, midbrain, and hindbrain
What does the central nervous system consist of
Brain and spinal cord
Forward part of the brain, which consists of the cerebral cortex, which is divided into 4 lobes
Forebrain
Right behind your forehead; eyebrows to the middle of your head; responsible for: movement, thinking and planning, language production (ability to speak clearly), general memory, decision making, mood, personality: brain cells called neurons (electrical wiring in the brain), frontal lobe neurons are not fully developed until age 25
Frontal lobe
In 1800’s or so, worked on a railroad, somehow had a long iron bar shot through his head, right through his frontal lobe; whole personality was changed
Phinnaeus Gage
On top of your head, behind frontal lobe; responsible for: sensitivity to pressure, temperature, pain, and perception
Parietal Lobe
This happens if your parietal lobe is damaged, you can only see half of something. (falls under perception)
Contralateral Neglect
One on each side, right above your ears, the bottom of the brain, in the middle; responsible for: hearing, understanding language, storing autobiographical things (remember things that have happened to you)
Temporal lobe
If you sustain damage to the temporal lobe, what may occur
Deafness, no understanding of language, and amnesia
Back of the brain with only one major responsibility: vision; Any type of damage will affect vision, major or severe damage will affect your vision severely
Occipital lobe
Located in the middle of the brain; separates forebrain from hindbrain; responsible for movement (along with frontal lobe), walking, general movement, visual tracking, reflexes that are triggered by sound (jumping because of noise, curiosity of looking at a loud noise
Midbrain
Consists of cerebellum, pons, and medulla
Hindbrain
Plays a major role in balance and coordination
Cerebellum
Connects cerebellum to the medulla
Pons
Regulates vital functions (breathing, heartbeat, etc.)
Medulla
You _____ unconscious during sleep
Aren’t
Reasons for being conscious during sleep
Most parts of your brain are still active, you can hear see and move
Subjective experience of the world; our bodies and our mental perspectives
Consciousness
Internal clock that everyone has that works on a 24 hour cycle
Circadian Rythmn
During the Circadian rhythm, what biological changes happen
Hormone release, change in brain waves, and your body temperature
What is the sleep hormone
Melatonin
When is melatonin released
Sometimes after lunch, and at night time.
