The disencapsulated mind: A premotor theory of human imagination.

Our premodern ancestors had perceptual, motoric, and cognitive functional domains that were modularly encapsulated. Some of these came to interact through a new type of cross-modular binding in our species. This allowed previously domain-dedicated, encapsulated motoric and sensory operators to operate on operands for which they had not evolved.

Visual perception can be thought of in two fundamentally different ways: (1) that what we see is determined by circuitry for detecting and representing object features and conditions in the physical world or (2) that what we see is determined empirically by neural associations based on the relative success of accumulated trial-and-error behavior. The evidence reviewed here indicates that the qualities we perceive are determined empirically. The reasons for this way of seeing are discussed.

Background: Reported effects of Hormone Replacement Therapy (HRT) on late-life neurodegenerative disease are inconsistent. Variability in the timing and formulation of HRT, plus whether an individual carries an Apolipoprotein (APOE) e4 genetic risk variant for Alzheimer's Disease (AD), likely contribute to conflicting results. Additionally, whilst many studies have focused exclusively on the effects of exogenous oestrogen, the inclusion of testosterone in HRT appears protective against AD pathology, specifically in APOE e4 carriers.

Anticounterfeiting technologies meet challenges in the Internet of Things era due to the rapidly growing volume of objects, their frequent connection with humans, and the accelerated advance of counterfeiting/cracking techniques. Here, we, inspired by biological fingerprints, present a simple anticounterfeiting system based on perovskite quantum dot (PQD) fingerprint physical unclonable function (FPUF) by cooperatively utilizing the spontaneous-phase separation of polymers and selective in situ synthesis PQDs as an entropy source. The FPUFs offer red, green, and blue full-color fingerprint identifiers and random three-dimensional (3D) morphology, which extends binary to multivalued encoding by tuning the perovskite and polymer components, enabling a high encoding capacity (about 10, far surpassing that of biometric fingerprints).

Two approaches to movement selection, if-then rules versus prospective planning, were investigated. Studies have shown that the rule-based approach leads to more efficient movement selection than the plan-based approach, though the resulting movements are the same. This dual-tasking study investigates two hypotheses explaining this discrepancy: The efficiency hypothesis states that the rule-based approach to movement selection is more efficient, and its advantage over the plan-based approach increases under any kind of enhanced task demands.
