Transcript of The Brain

The Brain Frontal Lobe Cerebrum Brain Stem Cerebellum twisty mass of gray matter
biggest part of the brain
divided into two halves called hemispheres creative tasks
the right hemisphere controls the left side of the body
analyzing nonverbal information
communicating emotion Left Brain language and math skills
the left hemisphere controls the right side of the body
produce and understand language Right Brain Parietal Lobe Temporal Lobe Occipital Lobe receive and process visual information
contains areas that help in perceiving shapes and colors
Problems After Injury
Damage to the occipital lobes can cause:
visual field defects
disordered perceptions of size, color, and shape planning
problem solving
impulse control
decision making
controlling our behavior and emotions
the left frontal lobe plays a large role in speech and language
Problems After Injury
Injury to the frontal lobes may affect:
impulse control
memory integrate sensory information form various parts of the body
contains the primary sensory cortex, which controls sensation (touch, hot or cold, pain)
tell us which way is up
help to keep us from bumping into things when we walk
Problems After Injury
Damage to the parietal lobes:
an inability to locate parts of your body
an inability to recognize parts of your body recognizing and processing sound
understanding and producing speech
various aspects of memory
Problems After Injury
Damage to specific parts of the temporal lobe
can result in:
hearing loss
language problems
sensory problems like the inability to recognize a familiar person's face balance
The cerebellum also allows us to:
stand upright
keep our balance
Problems After Injury
Damage to the cerebellum can result in:
uncoordinated movements
loss to muscle tone
an unsteady gait breathing
heart rate
blood pressure
it also plays a role in alertness and sensation
Problems After Injury
Injury to the brain stem can disrupt basic functions so that they are no longer regulated automatically. These functions can include:
heart rate
swallowing behavior
coordination of movements
some eye movements
sense of smell
muscle movements
skilled movements sense of touch
sensory combination and comprehension
some language and reading functions
some visual functions some hearing
visual memories
some language
some speech
some behavior and emotions
sense of identity The brain stem contains the
hypothalamus, optic chiasm, pituitary
gland, spinal cord, pineal body, and
ventricles and cerebral aqueduct. Facts: x x ( Interesting Facts: the brain weighs 3 lb.
your brain uses about 12 watts of power-a fraction of the energy of a household light bulb
every retina, eye, has a blind spot where the optic nerve exits to the brain
without the hypothalamus, which is in your brain stem, you'd keep eating and never feel full
you can not tickle yourself, because your brain anticipates the touch
your skin weighs twice as much as your brain
some dolphins have bigger brains than humans
after hearing it twice, Mozart played a 12-minute choral composition from memory
the idea of Frankenstein came to Mary Shelley in a dream
the longest bout of sleeplessness on record is 11 days the brain takes up 20% of your body's oxygen
a fifth of your blood is devoted to supplying your brain
your brain is 60% white matter and 40% gray matter
gray matter is thickest in girls at age 11, in boys at 12 years of age
the neurons you have at birth are all you will ever have
the billions of nerve cell allow you to think, remember, dream, see, hear, smell, taste, and touch
emotions help memories form and stick
sensory memories last just a fraction of a second
the part of your brain that recognizes an object is different from the part that locates it
most people can remember as many as 10,000 faces
without the brain you'd be dead by: Angela
