How does the brain integrate artificial body extensions? Using a custom-built finger-extending exoskeleton, we show that wearable augmentations are quickly integrated into body representation, with proprioceptive space adapting to the deviceโ€™s structure and function.

I'm particularly happy to see this preprint out! Lenny compellingly demonstrates, in a data-driven way, a coding scheme unifying distributed dimensions and category selectivity. The idea:Higher visual cortex comprises many partially overlapping tuning maps that include but go beyond category tuning.

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 (70โ€“72), which is evenly sampled
by the equidistant source surface layers. e) Each colored line represents the model evidence (relative
to the worst model, ฮ”F) 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 ฮ”F is
indicated by โ€œห„โ€. f) Result matrix summarizing ฮ”F across simulated source locations, with peak
relative model evidence marked with โ€œห„โ€. g) Error is calculated from the result matrix as the absolute
distance in mm or layers from the simulated source (*) to the peak ฮ”F (ห„). h) Bias is calculated as the
relative position of a peak ฮ”F(ห„) to a simulated source (*) in layers or mm.

Neural dynamics across cortical layers are key to brain computations - but non-invasively, weโ€™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!
