“Try to write your name by holding the pen between your teeth”. “Bad? Try
again”! “ After some practice you will see that you will be quite good at it”.
Explain why this is possible. (p. 271). What is hierarchical representation of
action sequences? (p. 269). Give an example of an hierchical control of action.
(Jfr figure 7.13 p. 269). Name 2 cortical motorareas, and at least 3 subcortical
nuclei (in eg basal ganglia) involved in motor actions (p 310). “Mr NN is asked
to raise his right arm, but for some reason he doesn´t manage to do it”. Discuss
possible reasons for this inability (aphasia – doesn´t understand; hemorrage in
the left hemsiphere – contralateral control of right arm which has become
paraplegic; apraxia etc).

“Why do all cats appear grey in the dark”? (p. 177-78). “Imagine watching a
film segment showing a big purple dog briefly presented in your right visual
field. Trace the flow of information about the dog and its color, shape, motion,
and position from the eye through the secondary visual areas (p. 177-88).
G:4 + article (Cognitive Neuroscience)
In cognitive neuroscience of aging three different kinds of approaches are used.
What are they called? Describe their strengths and weaknesses (e g table 2 in
the article), and discuss pros and cons for using computer modeling (G: p 117120).
G:6
What is object constancy? (ability to recognize an object in different situations).
What is a visual agnosia? (inability to recognize visually presented objects).
Name and describe two different subtypes of agnosia (e g apperceptive – p 226
and associative – p 229). How can you tell whether or not a person is suffering
from an agnosia or a memory loss? (Figure 6.22 p. 225).

Discuss how we normally, and in pathological cases, seem to perceive our –

Which are the 4 guidelines to be met for a substance to be classified as a

concept is relevant (see pdf fil).
G: 12+ aricle (“Causal Heterogeneity in Attention-Deficit/
Hyperactivity Disorder:….”)
Discuss different aspects of the neuropsychological aspects of attention (537551+ article), and relevant anatomical structures/areas.
G:3
Use the following concepts when briefly describing the development of the
nervous system: neuronal proliferation, neuronal migration, neuronal
determination and differentiation, synaptogenesis, and synapse elimination
(p. 90-101).
G: 10 + article (Pulvermuller..)
How is language represented within the cerebral hemispheres? (p 425). How is
Broca´s and Wernicke´s aphasia characterized or manifested? (p. 427-429), and
how can you rehabilitate these language disorders ? (relevant part in the article).
