_ not being able to recognize a familiar or famous face.
-Not able to recognize famous faces
-May resemble dementia, loss of memory
-Sometimes: one cannot identify e.g. birds (=
misidentification within a certain semantic category)
-Not able to learn new faces
What remains normal:
- Discrimination and matching of faces
- One recognizes a face as a face
-One may recognize a face by the voice, and extrafacial characteristics :
In other words, memories of that face are still intact
and can be retrieved
Prosopagnosia, not being able to recognize a familiar or famous face.

-many brain regions are involved in face recognition (false/true)
- only the fusiform gyrus (false/true)

Which areas are involved in face recognition?
-posterior temporal lobe
-anterior temporal lobe
-occipito-temporal lobe
- orbito-fronal cortex

- orbito-fronal cortex
the anterior temporal lobe and orbitofrontal cortex, plays a crucial role in empathy, impulse control, self-reflection, functions important for the development of one's personality. For face recognition, information about one's personality is a prerequisite.
Mental rotation and visuospatial agnosia: those functions are more related to the (left/right) hemisphere.

why does prosopagnosia often coincides with apraxia (dressing, constructional)?
Hints:
- damage in geniculostriate, tectopulvinar or STS?
- damage in parietal, temporal, occipital or frontal lobe?
why does prosopagnosia often coincides with apraxia (dressing, constructional)?
a lesion in a tertiary area such as the STS may not only cause a prosopagnosia as also the connections with the parietal lobe will be damaged, resulting in one or more types of apraxia.
Temporal lobe.
The lateral temporal cortex has intense connections (white matter/gray matter) with the medial temporal lobe, where the hippocampus and amygdala are located.

_ takes care of the emotional part of memory.
_ is dominant for spatial memory as it encompasses a navigation system: guides me through space, direct me the way back home etc.
1. amygdala
2. septum
3. Heschl gyrus
4. hippocampus
The amygdala takes care of the emotional part of memory.
The hippocampus is dominant for spatial memory as it encompasses a navigation system: guides me through space, direct me the way back home etc.
The hippocampus is not the only memory structure.
For episodic memory you need a complete network,including
Choose the 4 fitting structures:
1. the mammillary body
2. the thalamus
3. the fornix
4. the septum (part of the basal forebrain)
5. amygdala
6. Heschl gyrus
7. medulla oblongata
