Supplementary Information for Perception Flashcards
Describe the action of the oval and round window when there is soundwave
when there is soundwave, the oval window bulges in and the round window bulges out
Describe the functional organisation of the V1
and information from how many eye enters the CO blobs)
Layer 2-3: input from the koniocellular layers
Layer 4: input from the magnocellular (rapid changes) and the parvocellular layers (colour)
CO Blobs in the V1 are for colour perception (only from one eye)
Outside CO blobs (interblob): movement, orientation and depth
Layer 3 also feeds output to other regions of the brain
Explain the hierarchical feed forward model
After leaving V1, the neurones and the brain regions are getting more specialised for the input
however, there is still communication between the V1 and other regions
According to the slides, what is considered as the outer, middle and inner ear
outer
pinna, auditory canal and the tympanic membrane
middle: ossicles
inner: cochlea and the windows
what is the sterocilia
a tiny filament that is on top of the hair cells
what are the ions that are in the endolymph
K+ and CA2+
Signals from one ear are processed in…
both hemispheres
what are the two visual pathways and what are they for respectively
retinogeniculate pathway (visual perception)
retinohypothalamic pathway (melanopsin and bio clock)
name the Marr’s system of understanding recognition and the regions that are responsible
edges = LGN
lines = V1
curvature = V4
the visual regions are mostly if not all along the __ pathway
ventral
what is the face inversion effect
the difficulties to recognise a face that is up-side down compared to other objects such as houses and cars
what are the differences between human and rodent in terms of spatial navigation
same
hippocampal formation
papez circuit
different
human visual systems are more complex
rodents are nocturnal
what are the uses of the papez circuit
spatial navigation and memory
where is the PPA
along the parahippocampal gryus and the collateral sulcus
where are allocentric heading cells place in
the retrosplenial cortex
