An Umwelt is each species’ sensory world. We perceive what our senses detect, so our reality is 'filtered' and 'unique'. Our evolutionary past shapes how we navigate the world, our thoughts, dreams, and, of course, how the Hippocampus makes memories. 👇 https://t.co/IOUA4EZcgd

Evolution sculpts the brain's sensory adaptations. Because these adaptations differ markedly across species, it is challenging for humans to fully comprehend how other animals perceive the world....

Does predictive processing work more in the spectral compared to spike rate domain? Seems possible. For further reading check out: https://t.co/RdMCUrzpR2 2/2

In predictive coding (PC), higher-order brain areas generate predictions that are sent to lower-order sensory areas. Top-down predictions are compared with bottom-up sensory data, and mismatches...

@MillerLabMIT @MIT_Picower That's an interesting model, but how can we apply it to cortex to test whether traveling waves exhibit the characteristics of analog computing as Earl proposed?

Brain waves’ analog organization of cortex enables cognition and consciousness, suggests @MillerLabMIT at SfN. Awesome talk! Great recap here: https://t.co/J5K537j175 via @MIT_Picower Follow-up question: how can we test whether the waves actually perform computations?

On neuroscience’s big stage Nov. 15, MIT Professor Earl K. Miller proposed that thought and consciousness emerge from the fast and flexible organization of the cortex produced by the analog computa...

Jaxley: Training detailed brain models with backprop Biophysical neuron models are the gold standard for mechanistic explanations in neuroscience: they capture ion channels, dendritic trees and synapses in fine detail. But that detail comes with a price. To make these models

Nice perspective by Jake Westerberg and @Pieters_Tweet on accumulating evidence that Predictive Coding does not account for observed sensory response and that we need to update the model. For further reading, see also our recent piece: https://t.co/RXXpthGOZV

Great interview with Chancellor Diermeier about the values we hold at Vanderbilt and his bold vision for our University. I'm proud to be a part of this community, Go Dores! Dare to Grow!
Chancellor Daniel Diermeier joined @Morning_Joe today to discuss the university’s mission, the importance of institutional neutrality, growth in new cities, and Vanderbilt's success on and off the football field. Watch here: https://t.co/tnZ7r5eDiZ

Predictive coding has guided neuroscience for years but it does not account for the neuronal data. We review how patterns of feedback during spatial and temporal predictions are better captured by a family of opposing theories, collectively termed BELIEF. https://t.co/QU22KK7h7y

Great advice for giving strong scientific talks! Thanks for sharing @erturklab
I am often asked what the one skill is that young scientists should work on the most. My answer: your storytelling via presentations. The better you present, the more your ideas travel, the more doors open, and the more people want to work with you. A few tips: Have one clear

Very grateful to my co-authors for bringing their wisdom and courage to this conversation and to @NatureNeuro for publishing our opinion piece. We--the scientific community--have a lot of work to do to rebuild trust with the public.
Our piece arguing that all scientists need to engage with the public if we are to turn back the anti-science tide is out in NatNeuro today: https://t.co/v8CTcHd3T0;
