| Simulation Project Title |
Weren't we here before? Modelling Spatial Memory. |
| Type of model |
Systems model |
| Description |
The model mimics the processing behind a memory task: e.g. is the place the same between
subsequent images? Place can be constructed as a height-field map based on the single
egocentric viewpoint of the image, a non-trivial task + main challenge. The model predicts
lower performance correlating with less difference between the height-fields of two places.
Viewpoints can also change, requiring rotation of the height-field maps. The model also
predicts more error as a function of rotation angle. |
| Why complementary |
I'm currently analysing the fMRI and behavioural data of a spatial memory study separately.
Unifying these in a model could lead to insights that neither alone provide and explain how
behaviour is governed. A model could make clear predictions for future experiments with the
advantage that it does so in both fMRI and behavioural domains. The model may also be more
robust as it uses two data sources. Most models in this area use rat data, so a model with
human data would be a worthy addition. |
