What proportion of the digits recognized by healthy volunteers in the conventional dichotic listening test are typically those presented to the right ear?

The volunteers in the first experiments performed on split-brain humans had

The left and right cerebral hemispheres are connected by the

The left planum temporale corresponds roughly to __________.

A major difficulty in studying the asymmetry of the cortical language areas is

In comparison to English speakers,Italian speakers are less likely to be diagnosed as __________.

In contrast to the predictions of the Wernicke-Geschwind model,CT and structural MRI studies have identified aphasic patients who appear to have damage restricted to

Because cerebral lateralization is present in all five vertebrate classes,it must have fundamental survival advantages.It has been suggested that this advantage is that in some instances

Each hemisphere of a human split-brain patient is capable of completion.That is why on the chimeric figures test,each hemisphere sees

According to the Wernicke-Geschwind model,the visual form of a read word is translated into a meaningful auditory code by

The motor theory of the lateralization of cerebral function is that

The Z lens was developed by

Describe the groundbreaking study of Myers and Sperry on split-brain cats.Explain why it has been so influential,and describe three of its contributions.

In order to establish that the dichotic listening test is a valid test of language lateralization,Kimura showed that

A spoon is presented in the left visual field of a split-brain patient,and an apple is simultaneously presented in the right.Then,the patient is instructed to reach into two bags (one with each hand)and feel around until he comes up with the object that was presented on the screen.However,before the objects are withdrawn,the patient is asked to tell the experimenter what he has in each hand.The patient is likely to say,"I have

According to the Wernicke-Geschwind model,the neural output of the left frontal operculum (e.g.,Broca's area)goes to

The fact that left-hemisphere damage disrupts American Sign Language but not pantomime gestures supports the __________ theory of cerebral asymmetry.

Who were the neurosurgeons who performed the first major series of commissurotomies for the treatment of intractable epilepsy?
