By comparing species-specific developmental patterns, we can approach the question of how development shapes adult morphology and contributes to the evolution of novel forms. Studies of evolutionary changes to brain development in primates can provide important clues about the emergence of human cognition, but are hindered by the lack of preserved neural(More)
Besides Homo erectus (sensu lato), the eastern African fossil record of early Homo has been interpreted as representing either a single variable species, Homo habilis, or two species. In the latter case, however, there is no consensus over the respective groupings, and which of the two includes OH 7, the 1.8-million-year-old H. habilis holotype. This(More)
Despite mounting contrary evidence, the metabolic hypothesis is viewed as the predominant theory underlying neurovascular coupling, or the link between neural activity and cerebral blood flow. In a recent study, Huo et al. (Huo BX, Smith JB, Drew PJ. J Neurosci 34: 10975-10981, 2014) combined multimodal imaging and electrophysiology in experiments using(More)
