/2 Retinotopy is how the brain spatially maps visual input, organizing the world you see onto the surface of your cortex. Think of it as your brain's internal 2D layout of the visual field. Every point in space? Assigned a cortical coordinate.

My time at UQ has come to an end. Many thanks to the colleagues and students that made the experience so great. I’m not sure what’s next, but for now my wife and I have started a passion project. And I’d like to invite you all to join. Come follow @50DownUnder. RTs appreciated.

Very much enjoyed writing this methods-based book chapter with one of my favorite somatosensory researchers, Rosa Sanchez Panchuelo. And big thanks to @AshYork1 for providing a couple of banging figures from our high-res work. 2/3

Grateful to have had the opportunity to help out with this project. Setting up the 7T sessions @UQ_CAI to map the blindspot required a bit of a maneuvering. Couldn't have done it without co-author @AshYork1 and radiographer-extraordinaire @NicoleTatcheson.

Our study using a new reverse-correlation approach to mapping retinotopy of the blind spot is now published in Human Brain Mapping! w/ @PWBUrale @pucketta_m @AshYork1 & @Derek_Vis_Nerd doi.org/10.1002/hbm.25996

Highly accurate retinotopic maps of the physiological blind spot in human visual cortex

In each eye we have a small region of blindness corresponding to the optic disc, because the retina contains no photoreceptors here. This physiological blind spot is an excellent model system for...

Despite a serious effort to socially distance ourselves, we received word today that @bellepropertyau will be sending tradespeople from 4 different companies into our rental over the next week. Told us there is nothing we can do about it. And no, its not for emergency repairs.

The primate visual system is hierarchically organized with increasingly complex features being processed up the hierarchy. Inspired by the neurobiology underlying vision, deep neural networks were built to imitate these properties. 2/n
