Ch 3b The Brain

The Brain cards

TermDefinition
Two parts of the Human Nervous System Central NS and Peripheral NS
Two parts of the Central Nervous System Brain and Spinal Cord
Two parts of the Peripheral Nervous System Autonomic NS and Somatic NS
Two parts of the Autonomic NS Sympathetic and Parasympathetic NS
Two parts of the Somatic NS Afferent NS and Efferent NS
Sympathetic NS Part of the Autonomic NS, it mobilizes: pupils and bronchial tubes dilate, adrenaline flow increases
Parasympathetic NS Part of the Autonomic NS, it conserves: pupils and bronchial tubes constrict, adrenaline flow decreases
Afferent NS Part of the Somatic NS, these nerves go from body to brain (sensory neurons)
Efferent NS Part of the Somatic NS, these nerves go from brain to body (motor neurons)
Spinal cord Carries nerves to and away from the body and brain
Meninges three layers, it surrounds the spinal cord and protects it
Cerebrospinal Fluid Fluid flows up the spinal cord to the brain and back like a pump
Pseudotumor Increased cerebrospinal fluid causing increased pressure in the brain: headaches, blurry vision
Treatment for pseudotumor Shunt in the spine or brain that regulates the amount of CS fluid going to the brain
Three major parts of the brain Hindbrain, Midbrain and Forebrain
Hindbrain First to develop--Comprised of the medulla oblongata, pons and cerebellum--most primitive part of the brain (brainstem)
Midbrain Next to develop --Comprised of reticular formation
Forebrain Last to develop as people stood erect. Largest brain region--comprised of all four lobes
Cerebrum the brain
Cerebral Cortex Convoluted layer of the brain--cushions brain like a pillow
Occipital Lobe Vision
Temporal Lobe Hearing, Taste and Smell. Left temporal lobe houses Wernicke's Area
Parietal Lobe Relays sensory information from the thalamus to the proper lobes. Responsible for touch
Forebrain Most sophisticated part of the brain--goal planning, movement, knowing right/wrong. Left part of frontal lobe is Broca's Area
Broca's Area Left frontal lobe--responsible for producing speech
Wernicke's Area Left temporal lobe--understanding speech
Aphasia Loss of speech
Limbic System in Forebrain--the amygdala, hippocampus and hypothalamus
Amygdala Fight or flight response--handles emotion especially fear
Hippocampus Learning and Memory--how to remember? The hippo's on the campus learning and putting facts into memory
Thalamus In Forebrain--accepts sensory information and relays it to the somatosensory cortex that relays it to the parietal lobe which sends it on to the proper lobe. One exception is smell which goes directly from the cerebral cortex to the temporal lobe.
Hypothalamus Manages the pituitary gland, responsible for keeping body in homeostasis, regulates heartrate, BP, temperature: part of limbic system
Reticular formation Midbrain handles some sensory info, keeps us alert, and controls some somatic functions
Pons Connects the hind and mid brain
Medulla Part of the brain stem--Autonomic functions of the brain--heart rate, circulation, breathing
Cerebellum Movement and balance
Brainstem Connects the spinal cord to the brain--made of the medulla and pons and the midbrain. Also connects the brain to the cerebellum
EEG--electroencephalograph Monitors brain waves and maps them to states of consciousness and types of sleep
Lesioning Used for research on animals, a electric probe is inserted in the animal's brain to destroy tissue to map functions of the animal's brain
ECT: electro-convulsive therapy Small shocks are sent to the brain in cases of deep chronic depression, bipolar disorder or schizophrenia to regulate neurotransmitter production and function
TMS--transcranial magnetic stimulation small paddle that can emit electricity into the brain to map function. Also used for mood disorders
PET Scan-positon emission topography Inject dye into the brain to see if there are blocked arteries (best for checking for strokes or aneurysms Can examine brain functions
CT Scan Multiple x-ray scans that show structures in the brain
MRI (magnetic resonance imaging) Uses magnetic fields and computer-generated radio waves to detect structure--more precise than the CAT scan
fMRI A more sophisticated technology than an MRI, an fMRI will show structure and function--very expensive equipment
Two Hemispheres of the Brain Left and Right
Left Brain Language, Math, Science, Reasoning, Playing a musical instrument and right hand control
Right Brain Artistic ability, seeing in 3D, Composing music, creative insight and left hand control
Corpus Callosum Fibers that connect the two hemispheres of the brain and allow the two halves to talk to each other
Gazzaniga and Sperry Performed the split brained study to understand the different functions of the brain and how they relate to each other. They did not split the brains of subjects! They used the population of people who already had the corpus callosum split to help their
Gazzaniga's famous split-brain study Know how it was carried out, and the results--see handout
Plasticity Resembles silly putty and is malleable.
What can sculpt the brain? Repeated practicing a certain motion
Monozygotic Twins: Nature v. Nurture Behavior Identical Twins 99.2% genetic similarity. desired population for nature v. nurture studies. Heritability Ratio: 0
Dizygotic Twins: Nature v. Nurture Behavior Twins developed in two amniotic sacs--siblings--50% genetic material: Heritability Ratio 1:2
Evolutionary Behavior Evolutionary Psychologists claim that we carry survival and reproduction behavior in our DNA from clan times

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
