AbstractUnderstanding the dynamical transformation of neural activity to behavior requires new capabilities to nonlinearly model, dissociate and prioritize behaviorally relevant neural dynamics and test hypotheses about the origin of nonlinearity. We present dissociative prioritized analysis of dynamics (DPAD), a nonlinear dynamical modeling approach that enables these capabilities with a multisection neural network architecture and training approach.

Given the way that Mark S. George describes the early days of his experiments with transcranial magnetic stimulation (TMS), potential patients might be wary. A professor of psychiatry at the Medical University of South Carolina and a pioneer of TMS, George recounts, for example, how the electrical circuits delivering current to coils would explode “with a blue flame” not all that far from the subject and the scientist.

For a number of years, I have argued that we are now, thanks to the effects of human-caused warming, experiencing a new class of monster storms—”category 6” hurricanes. That is to say, we are witnessing hurricanes that—by any logical extension of the existing Saffir-Simpson scale—deserve to be placed in a whole separate, more destructive category from the traditionally defined (category 5) “strongest” storms. Up until now, that was really just a matter of opinion (1).

The shape of Nature’s stingers revealedEdited by William Nix, Stanford University, Stanford, CA; received September 19, 2023; accepted December 6, 2023SignificanceAs ubiquitous defense mechanisms in Nature, stinger-like structures cover a size range over six orders of magnitude. While their composition varies, we uncovered a common geometric trait: a non-linear relationship between diameter and distance from the tip, following a power law with an exponent universally between 2 and 3.
