The discussions show strong agreement with the article's thesis, with examples such as mentions of the conservation of brainstem functions and observations of patients with brain abnormalities, which emphasize the potential for consciousness beyond the cortex. The tone is analytical and curious, reflecting an engagement with the scientific evidence and theoretical challenges presented, underscoring its high impact on contemporary neuroscience debates.
AgreementStrong agreement
Most discussions acknowledge and support the article's challenge to cortical-centric views of consciousness, emphasizing the importance of the brainstem in conscious experience.
InterestModerate interest
There is a moderate level of interest, demonstrated by curiosity about the implications of consciousness without a cortex and references to related studies.
EngagementHigh engagement
Participants actively cite scientific studies, question traditional assumptions, and discuss implications, indicating deep engagement.
ImpactHigh impact
The conversations suggest that this publication influences ongoing debates and encourages reconsideration of long-standing ideas in neuroscience.
Abstract in brief
The article reviews evidence from various fields to explore how consciousness might be organized in the vertebrate brain, emphasizing a novel principle linking target selection, action, and motivation to optimize real-time integration for behavior.
It proposes that an upper brainstem system, which has been conserved throughout evolution, plays a central role in conscious function by integrating information from the cerebral cortex and maintaining coherent behavior, even in the absence of cortical input.
The findings challenge the traditional view that consciousness relies solely on the thalamocortical complex, suggesting instead that brainstem mechanisms are fundamental to conscious experience, as evidenced by mammals and children born without a cortex still exhibiting consciousness.
The idea that a cerebral cortex is required for sentience (understood as having any conscious experience) is just laughable.

Carrots dont have brains or central nervous systems or nociceptors so thats evidence they arent conscious. Am I saying theres no possible way they're conscious?No, but my credence on them being conscious is very small
@GurReptsSohn @davidmanheim @allTheYud @IsaacKing314 @BenKorpan Idk why beings would need to have a model of themselves to be able to have negative subjective experiences. Do you think consciousness (ability to have subjective experiences) cant happen without awareness of oneself?

Turns out humans can do quite a lot with a cortex... consciousness is fascinating https://t.co/Zkl4UJGDfa
@____BRODIE____ @markianrubin @maartengm @WKCosmo @skdh Sure, will send some things over the coming days. Popular scientific ones, or original articles? On consciousness requiring a cortex, this is a good starting point: https://t.co/BctKG7Y0be
@ScottMatte @naught_ewe @Maximumatheist Idk most of them die early
The brainstem is critical to consciousness. People have been focusing on the cortex bc that’s what makes us really smart especially with memory, but mere consciousness is more basic than memory.
