Was fun presenting our work on network localization of aphantasia at #ASSC @assc28.bsky.social - I get pretty excited about #consciousness and visual mental imagery

By analyzing rare cases we show that lesions associated with criminality intersect the right uncinate fasciculus more than other lesions & more than other white matter tracts. Damage to the right uncinate may play a causal role in criminal behavior, especially violent crime. @synapsekid.bsky.social

Can brain injury cause the loss of visual imagination?

We studied #aphantasia due to brain injury. Lesions were in many different regions but 100% were connected to the fusiform imagery node - a region active during visual mental imagery @braincircuits.bsky.social

What is midrash? Interesting analysis by Ishay Rosen-Zvi @harvarddivinity.bsky.social on unique midrashic terminology (and apparently the Qumran folks thought there was a Sefer haBrit given to Abraham 📜)

Cool talk by Aaron Boes on clinical applications and cognitive prognosis from network neuroimaging @bostonchildrens.bsky.social @harvardmed.bsky.social

Amazing work by Julian Kutsche and the many other collaborators. @drdrxanderli.bsky.social

Reduced function or injury to the frontal pole may increase creativity by disengaging the self-monitoring & cognitive control actions of the frontal pole to allow novelty seeking & creativity to be unleashed. @braincircuits.bsky.social @foxmdphd.bsky.social @julianneumann.bsky.social

Since visual mental imagery requires at least drawing visual images from memory & making them available for experience there’s no need for either/or - aphantasia could arise from deficits in visual memory or w/ processing of visual priors as you suggest re: heterogeneity @alfredospagna.bsky.social

Beautiful lecture by Dr. Schmahmann on the Systems Neuroscience of White Matter Pathways in honor of Dr. Filley @cumedicalschool.bsky.social @harvardmed.bsky.social

How can someone lose a part of their vision and not know it? Visual deficits that go unnoticed challenges the view that our conscious experiences are what we know best. We review the surprisingly common phenomena @braincircuits.bsky.social Last day of free access to the full PDF⏱️ t.co/CBBLrhy5sB
