Laboratory experiments

Gazzaniga et al. set up BLANK BLANKs in which they changed an independent variable, such as showing a light in either the right or the left side of the subject's vision and then they measured a dependent variable, like whether they could say they saw the light or could only point at it. Any light in the left field of vision could only be pointed at, while lights in the right field of vision could be verbally identified.

Split-brain

In a BLANK-BLANK patient, when a light is shown in his right field of vision, he can verbally identify it because this field is channeled directly to the left hemisphere, specifically to Broca's Area, which is dedicated to speech production.

Right

In a split-brain patient, when a light is shown in his BLANK field of vision, he can verbally identify it because this field is channeled directly to the left hemisphere, specifically to Broca's Area, which is dedicated to speech production.

Verbally

In a split-brain patient, when a light is shown in his right field of vision, he can BLANK identify it because this field is channeled directly to the left hemisphere, specifically to Broca's Area, which is dedicated to speech production.

Hemisphere

In a split-brain patient, when a light is shown in his right field of vision, he can verbally identify it because this field is channeled directly to the left BLANK, specifically to Broca's Area, which is dedicated to speech production.

Seizures

Since Michael Gazzaniga's patients had to have surgeries to eliminate BLANKs, he was provided the opportunity to run natural experiments on them to see how the pre-existing absence of the corpus callosum would impact behaviors and perceptions.

Natural experiments

The key difference between BLANK BLANKs and laboratory experiments is that the independent variable is purposely manipulated by researchers during the second, while it is pre-existing during the first.

Localization

The term BLANK refers to the notion that each different area of the brain has specific functions, as evidenced by the fact that Sarah Scott's stroke created a lesion, damaging Broca's Area and causing aphasia.

Stroke, lesion

The term localization refers to the notion that each different area of the brain has specific functions, as evidenced by the fact that Sarah Scott's BLANK created a BLANK, damaging Broca's Area and causing aphasia.

Production, comprehension

Though speech BLANK and BLANK are located in two different parts of the left hemisphere, the first is in the posterior (rear part of the) frontal lobe, and the other is in the medial (middle part of the) temporal lobe.

Medial

Though speech BLANK and BLANK are located in two different parts of the left hemisphere, the first is in the posterior (rear part of the) the frontal lobe, and the other is in the BLANK (middle part of the) temporal lobe.

Posterior

Though speech production and comprehension are located in two different parts of the left hemisphere, the first is in the BLANK (rear part of the) frontal lobe, and the other is in the medial (middle part of the) temporal lobe.

Frontal, temporal

Case studies

Unique events often lead to often horrible lesions to brain tissue, but it is researchers who perform BLANK BLANKS on these unique individuals that bring to light localized functions that had been produced in these areas before the damage occurred.

Localization, lateralization

Whereas BLANK is the term that denotes specific brain functions occurring in and relying upon different areas of the brain, BLANK refers to the communication process that occurs between these various locations, made possible by connecting neurons.

Broca's aphasia

Within the decade that followed the discovery of Tan's lesion and the resulting BLANK BLANK, Carl Wernicke discovered a lesion in another patient's brain, this time in the temporal lobe, which robbed the subject of speech comprehension, a problem called Wernicke's aphasia.
