Hello,
Don't forget our new semester of seminars kicks off today at 4pm with two
exciting talks!
We will be hearing from Dr Lauren Welbourne with a short talk titled
"*Measuring
binocular combination of luminance and chromatic stimuli using fMRI"* and
Dr David Watson with a talk titled *"Mapping the connectivity of the scene
network in the human brain"* (see abstract below).
We really hope to see everyone at YNiC! The talks will take place *today
(Thursday the 28th) at 4pm*. If you are unable to attend the talk in
person, you can catch it on zoom using the following link:

We look forward to seeing you then!!
Many thanks,

*Mapping the connectivity of the scene network in the human brain*
The perception of places has been linked to a network of scene-selective
regions in the human brain (OPA: occipital place area; PPA: parahippocampal
place area; RSC: retrosplenial complex). However, the connectivity of these
regions to each other and the rest of the brain remains poorly understood.
Here, we measured the functional and structural connectivity of the scene
network. Functional connectivity, measured at rest and during movie
watching, revealed a bias between posterior and anterior scene regions that
have been implicated in perceptual versus mnemonic aspects of scene
perception. For example, OPA and posterior PPA showed greater connectivity
with visual and dorsal attention networks, which may play a role in the
visual representation of scenes. In contrast, anterior PPA and RSC showed
preferential connectivity with default-mode and frontoparietal control
networks and the hippocampus, which may reflect our memory for places. We
also measured the structural connectivity of the scene network using
diffusion tractography. This indicated both similarities and differences
with the functional connectivity, highlighting distinctions between
posterior and anterior but also ventral and dorsal scene regions. These
findings provide a map of the connectivity of the scene network, informing
possible roles for scene-selective regions in brain function and human
behaviour.
