Did you know that catecholamines can reduce choice history biases in perceptual decision-making? 🧐🔍

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖
Contents of visual predictions oscillate at alpha frequencies
Predictions of future events have a major impact on how we process sensory signals. However, it remains unclear how the brain keeps predictions online in anticipation of future inputs. Here, we combin...

Long time in the making: our preprint of survey study on the diversity with how people seem to experience #mentalimagery. Suggests #aphantasia should be redefined as absence of depictive thought, not merely "not seeing". Some more take home msg:

Really enjoyed my weekend read on 𝐚𝐜𝐭𝐢𝐯𝐞 𝐟𝐢𝐥𝐭𝐞𝐫𝐢𝐧𝐠: local recurrence amplifies natural input patterns and suppresses stray activity. This review beautifully argues that sensory cortex itself is a site of memory and prediction. Food for thought on hallucinations!

The brain is incredibly densely connected. Human cerebral cortex may have as many as *one trillion* connections.

Most of those cortical connections are recurrent, inside each area. What do they do?

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

Colors leave unique ‘maps’ in our brains, so consistent across people that Michael Bannert and Andreas Bartels (both MPI for Biological Cybernetics) could predict which color someone saw...just from fMRI data. 🌈🧠 Their findings point to deep evolutionary roots in how we perceive color.

🚨🚨🚨PREPRINT ALERT🚨🚨🚨
Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!
Overview of the simulation strategy and analysis. a) Pial and white matter boundaries surfaces are extracted from anatomical MRI volumes. b) Intermediate equidistant surfaces are generated between the pial and white matter surfaces (labeled as superficial (S) and deep (D) respectively). c) Surfaces are downsampled together, maintaining vertex correspondence across layers. Dipole orientations are constrained using vectors linking corresponding vertices (link vectors). d) The thickness of cortical laminae varies across the cortical depth (70–72), which is evenly sampled by the equidistant source surface layers. e) Each colored line represents the model evidence (relative to the worst model, ΔF) over source layer models, for a signal simulated at a particular layer (the simulated layer is indicated by the line color). The source layer model with the maximal ΔF is indicated by “˄”. f) Result matrix summarizing ΔF across simulated source locations, with peak relative model evidence marked with “˄”. g) Error is calculated from the result matrix as the absolute distance in mm or layers from the simulated source (*) to the peak ΔF (˄). h) Bias is calculated as the relative position of a peak ΔF(˄) to a simulated source (*) in layers or mm.

Rewarding animals to accurately report their subjective #percept is challenging. This study formalizes this problem and overcomes it with a #Bayesian method for estimating an animal’s subjective percept in real time during the experiment @plosbiology.org 🧪 plos.io/3HaxiuB
Two examples of how contextual information can bias visual perception. Top: Luminance illusion created by shadows (source: https://persci.mit.edu/gallery/checkershadow). Square B looks brighter than square A but has the same luminance, i.e., they have identical grayscale values in the picture. Bottom: Perception of object motion is biased by self-motion. The combination of leftward self-motion and up-left object motion in the world produces retinal motion that is up-right. If the animal partially subtracts the optic flow vector (orange dashed arrow) generated by self-motion (yellow arrow) from the image motion on the retina (black arrow), they may have a biased perception of object motion (red arrow) that lies between retinal and world coordinates (green arrow).
