Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Atypical Predictive Processing Is Associated With Sensory Over‐Responsivity in Autism

Autism Research, EarlyView.
ABSTRACT Autism is characterized by sensory processing atypicalities including sensory over‐responsivity (SOR), a heightened negative response to sensory stimuli. Although the neural mechanisms underlying SOR are not fully understood, SOR has been associated with sensory‐limbic hyper‐reactivity during sensory stimulation.
