Serotonergic-dependent awareness is required for trace conditioning in honeybees [PDF]
Summary: 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,

In standard (first-order) Pavlovian conditioning protocols, pairings of an initially neutral conditioned stimulus (CS) and a biologically significant unconditioned stimulus (US) result in the formation of a CS-US association.

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.

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]
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.

Higher-order trace conditioning in newborn rabbits
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 ...

Hierarchical architecture of dopaminergic circuits enables second-order conditioning in Drosophila
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 initial conditions with massive neutrinos
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).

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 ...

Cognitive Reserve and Anxiety Interactions Play a Fundamental Role in the Response to the Stress
The aims of the present study were to assess the possible interaction between Cognitive Reserve (CR) and State Anxiety (SA) on adrenocortical and physiological responses in coping situations. Forty healthy, middle-aged men completed the Cognitive Reserve
