Exam 2 Flashcards
How did we figure out the localization of language?
Lesion studies, stimulation studies and imaging studies.
What happens when you present an object to the right hemisphere by touching it with left hand or presenting in the left visual field?
- Patient can pick out the correct object with left hand, but cannot with right hand
- Patient claims nothing was presented
What happens during neural maturation?
Dendrites and axons develop.
What is the Kennard Principle?
That functions are spared when injury happens during infancy–before 1.
What is alternating attention?
Ability to shift focus and move between tasks with different cognitive requirements.
What conditions are caused by incorrect pathway formation?
Athetosis and dystonia.
Complete this graph of the cognitive-emotional interaction theory.


Name the three types of inattention.
Inattentional blindness
Change blindness
Attentional blink
What is a neural tube?
A rolled-up sheet of cells that will form the brain and spinal cord. It is formed 3 weeks after conception.
What abnormal development is this?

Polymicrogyria
What behavioral changes happened in monkeys after frontal lesions?
- Reduced social interaction
- Loss of social dominance
- Inappropriate social interaction
- Altered social preferences
- Reduced affect
- Reduced vocalization
What happens when you show a word in the left visual field of a split brain patient?
They do not report seeing the word but can draw the word–right hemisphere.
List the embryonic development of the cortical gyri in order.
- Gyrus rector, insula, cingulate
- Parahippocampal, superior temporal
- Prerolandic and postrolandic, middle temporal, superior and middle frontal, occipital
- Inferior and transverse temporal, medial and lateral orbital, angular, supramarginal
- Paracentral
- Anterior and posterior orbital
Which hemisphere is dominant for facial recognition?
The right.
Identify the word processing areas.


Describe the Wernicke-Geschwind model.
A model that explains the relationship between Broca’s and Wernicke’s areas.
Begins at the angular gyrus (posterior temporal lobe). Information flows towards Broca’s area through
- Wernicke’s area (spoken word comprehension, sound images of words)
- Arcuate fasciculus (connects W with B)
- Broca’s area (motor programs for speaking words)
Complete Posner’s Attention Model


What kind of amnesia is linked to damage to anterior thalamic nuclei?
Anterograde amnesia.
What is the difference between short-term and working memory?
The short-term memory is a temporary storage of information, whereas the working memory allows for temporarily storing and manipulating information.
Describe the role of the cerebellum in memory.
Classical conditioning.
Describe the Papez theory of emotion.
Limbic structures (thalamus, hypothalamus, mammilary bodies, cingulate gyrus and hippocampus) act on the hypothalamus to produce emotional states.
What are the four components of emotion?
- Physiology
- Distinctive motor behaviour
- Self-reported cognition
- Unconscious behaviour
In which hemisphere is the speech if a dichotic listening subject reports hearing in the right ear?
Left hemisphere.
What is Kluver-Bucy syndrome?
It results from bilateral damage to to amygdala and inferior temporal cortex.
Symptoms include:
- Tameness and loss of fear
- Indiscriminate dietary behaviour (will eat anything)
- Indiscriminate sexual activity
- Hypermetamorphosis: irresistible impulse to notice and react to everything in sight
- Examine objects by mouth
- Visual agnosia
