| Simulation Project Title |
Mechanisms behind perceptual suppression during eye movements. |
| Type of model |
Systems model |
| Description |
Mechanisms behind the loss of visual sensitivity during an eye movement are as yet poorly
understood. I aim to produce a biologically based model of the cause of saccadic a-perception
based on the idea that eye movements either affect the tuning of visual neurons or introduce
noise into the processing. Variations of this model that predict distinctive patterns of
performance will be assessed using behavioural data collected within an equivalent noise
framework. |
| Why complementary |
Presently, I collect behavioral and fMRI data to understand saccadic a-perception. The
project will provide a link between these data sets; the model will be developed on the basis
of behavioral data and used to predict BOLD and single cell activation in visual and eye
movement associated regions of cortex during saccades. Combining novel, model-based
predictions with solid experimental data (BOLD and single-cell) can provide truly new insight
into neural mechanisms of saccadic suppression. |
