Lecture 6 Flashcards
What do neuron’s work as? What is the importance of this?
dsdasdad
What is the phase locking mechanism? What happens if aligned? What happens if not aligned?
sdasdads
How is the AND gate involved with the phase locking mechanism seen?
edasdasd
What is coincidence detection?
dasdads
What is the speed of an AP? What is a consequent of this?
dsdasd
What is the anatomy of the pathway the action potential takes?
dsd
Where does the AP travel from the cochlear nucleus? Why is this important? What is the consequence of this?
sdasd
What is the Jeffress model of coincidence detection for sound localisation? What are the features of it? What animals is this model involved in?
sdasd
Why only respond when AP from both the R and L ear arrive together?
dadsad
What are the components needed for the calculation of ITD?
sdasdas
How is ILD calculated? What position is this used to compute?
wsdasda
How can compute the compute the sound direction using as a cue the ILD? What is needed? What are the components involved?
dsads
What is the balance needed in ILD?
ASDADS
Where does the midbrain auditory localisation pathway converge?
DSADASDASD
Where do the MSO neurons project to? What are the neuron’s tuned to? What manner do they project in?
dadasdad
Why are the frequency bands not a good final representation of sound location?
dasda
What is phase ambiguity?
dasdasda
How to solve the problem of phase ambiguity? How does the brain solve this problem? What are the components involved?
dsadasd
Why is the visual system important in hearing and sound localisation?
dasdasda
What was the experiments which they did to show the recalibration of the auditory space map by the visual map? What did this experiment show?
wdasdasd
Where is the tonotopic information established? Which components and pathways is it preserved?
dsadasd
Where is it not preserved? Why?
dsadasd
In these areas what are the special properties of the neuron?
dsadasd
Why is this feature of multimodal information?
