|
Myelin |
insulating sheath that speeds up the transmission of impulses along an axon. |
|
|
Glia |
cells that support the neurons in many ways such as by insulating them, synchronizing activity among neighboring neurons, and removing waste products. |
|
|
Action potential |
an excitation that travels along an axon at a constant strength, no matter how far it travels. |
|
|
Occipital lobe |
at rear of the head, is specialized for vision. |
|
|
Temporal lobe |
left and right sides of the head, is the main area for hearing and certain aspects of vision. |
|
|
Amygdala |
structure in the temporal lobe, responds strongly to emotional situations. |
|
|
Parietal lobe |
forward from the occipital lobe, is specialized for the body senses, including touch, pain, temperature, and awareness of the location of body parts in space. |
|
|
Primary somatosensory cortex |
strip in the forward portion of parietal lobe, has cells sensitive to touch in various body areas. |
|
|
Prefrontal cortex |
forward sections of frontal lobe, are important for memory of what has just happened and what you are planning to do next. |
|
|
Mirror neurons |
found in several brain areas, are active when you make a movement and also when you watch someone else make a similar movement. |

set of axons that connect left and right hemispheres of the cerebral cortex. |
|
|
Epilepsy |
condition in which cells somewhere in the brain emit abnormal rhythmic, spontaneous impulses. |
|
|
Electroencephalograph |
uses electrodes on the scalp to record rapid changes in brain electrical activity. |
|
|
Positron-emission tomography |
records radioactivity of various brain areas emitted from injected chemicals. |
|
|
Functional magnetic resonance imaging |
uses magnetic detectors outside the head to compare the amounts of hemoglobin with and without oxygen in different brain areas. |
|
|
Cerebellum |
part of the hindbrain, is important for any behavior that requires aim or timing. |
|
|
Oxytocin |
hormone released by women when nursing a baby and by both men and women during sexual activity. |
|
|
Binding problem |
the question of how separate brain areas combine forces to produce a unified perception of a single object. |
