where is the Limbic System?
|
border of the brainstem and the cerebrum
|
|
|
what is the function of the Limbic System?
|
associated with emotion such as fear, aggression and drives for food and sex
|
|
|
what three parts make up the Limbic System?
|
the hippocampus, amygdala and hypothalamus
|
|

what is the the Amygdala?
|
two neural clusters liked to fear and anger

where is the Hypothalamus located?
|
below the thalamus
|
|
|
what is the function of the Hypothalamus?
|
directs "maintenance activities" such as eating and body temperature
governes endocrine system |
|
|
what is a "split brain"
|
a condition resulting from the severing of teh fibers connecting the two brain hemispheres, especially the corpus callosum
|
|
|
what four ways do we have to study the brain?
|
EEG
PET MRI fMRI |
|
|
what does an EEG do?
what does it stand for? |
amplifies and records electrical activity on the brain's surface, measured with electrodes on the scalp
electroencephalogram |
|
|
what does a PET scan do?
what does it stand for |
creates a visual display of activity by introducing radioactive glucose to the brain
positron emission tomography |
|
|
what does an MRI do?
what does it stand for? |
uses magnetic fields and radio waves to produce computer generated images of soft tissue
magnetic resonance imaging |
|
|
how does an MRI differ from a fMRI
what does fMRI stand for? |
an fMRI is used to reveal blood flow in the brain and show brain activity while an MRI shows brain anatomy
functional magnetic resonance imaging |
|
|
what our our "three brains"?
why do we have them? |
Reptilian
Limbic Neocortex each is a section that developed during separate points in our evolution |
|
|
what is the Corpus Callosum
|
the large band of neural fibers connecting the two brain hemispheres
|
|
|
what is the specialty of the right hemisphere
|
inferences
making speech clear orchestrates our sense of self sensory input and motor output from the left side of the body |
|
|
what is the specialty of the left hemisphere?
|
calculations
literal interpretations language sensory input and motor output from the right side of the body |
