Serotonergic-dependent awareness is required for trace conditioning in honeybees [PDF]
iScienceSummary: In humans, trace conditioning—where a temporal gap separates conditioned (CS) and unconditioned (US) stimuli—requires awareness and is sensitive to distraction, unlike delay conditioning. Here, we show that honeybees exhibit comparable features,

Higher-order conditioning and the retrosplenial cortex. [PDF]
Neurobiol Learn Mem, 2016 The retrosplenial cortex (RSC) is known to contribute to contextual and spatial learning and memory. This is consistent with its well-established connectivity; the RSC is located at the interface of visuo-spatial association areas and the parahippocampal-hippocampal memory system.

Frontiers in Behavioral Neuroscience, 2022 Stimuli in reality rarely co-occur with primary reward or punishment to allow direct associative learning of value. Instead, value is thought to be inferred through complex higher-order associations.

Frontiers in Behavioral Neuroscience, 2021 The ability to form associations between different stimuli in the environment to guide adaptive behavior is a central element of learning processes, from perceptual learning in humans to Pavlovian conditioning in animals.

No relevant differences in conditioned pain modulation effects between parallel and sequential test design. A cross-sectional observational study [PDF]
PeerJ, 2021 Background Conditioned pain modulation (CPM) is measured by comparing pain induced by a test stimulus with pain induced by the same test stimulus, either during (parallel design) or after (sequential design) the conditioning stimulus.

Hierarchical architecture of dopaminergic circuits enables second-order conditioning in Drosophila
eLife, 2023 Dopaminergic neurons with distinct projection patterns and physiological properties compose memory subsystems in a brain. However, it is poorly understood whether or how they interact during complex learning.

Higher-order optimality conditions for a minimax [PDF]
Bulletin of the Australian Mathematical Society, 1996 Higher-order necessary and sufficient optimality conditions for a nonsmooth minimax problem with infinitely many constraints of inequality type are established under suitable basic assumptions and regularity conditions.

Higher-order trace conditioning in newborn rabbits
Learning & Memory, 2022 Temporal contingency is a key factor in associative learning but remains weakly investigated early in life. Few data suggest simultaneous presentation is required for young to associate different stimuli, whereas adults can learn them sequentially. Here, we investigated the ability of newborn rabbits to perform sensory preconditioning and second-order ...

Technologies, 2021 Heating, ventilation and air-conditioning (HVAC) systems play a key role in shaping office environments. However, open-plan office buildings nowadays are also faced with problems like unnecessary energy waste and an unsatisfactory shared indoor thermal ...

Higher order initial conditions with massive neutrinos
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The discovery that neutrinos have mass has important consequences for cosmology. The main effect of massive neutrinos is to suppress the growth of cosmic structure on small scales. Such growth can be accurately modelled using cosmological N-body simulations, but doing so requires accurate initial conditions (ICs).
