|
Broca/Wernickesa |
areas involved in sign language although not the only ones |
|
|
Brocas area activation |
when percieving ASL sentences contradicts the assumption that it is only involved in speech production |
|
|
Brocas area level |
of activation depends onwhen they aquired the second language |
|
|
Greater cortical levels |
associated with doing mental calculations in english opposed to just mandarin |
|
|
Medial temporal lobe injury |
caused problems for working memory the ability to process new events and facts |
|
|
greater activation in front portion of middle temporal lobe |
when viewing words they had studied |
|
|
greater activation in psterior medial temporal lobe |

region in the temporal cortex involved in memory |
|
|
damage to prefrontal cortex |
could not hold a memory in head |

prefrontal cortex dysfunction |
associated with elevated dopamine levels |
|
|
brain volume larger |
in autistic people |
|
|
mirror neuron system |
encoding intentions observed in actions as well as themselves |
|
|
Wernickes area and the posterior cortical system |
are adapted for reading no greater activation in those with dyslexia when material got harder |
|
|
disruption in psterior cortex and association cortex |
encompassing both traditional visual and language regions |
|
|
reduced activation in temopparital regions |
in those with dyslexia |
