Attenuation processes in positive social emotion upregulation: Disentangling functional role of ventrolateral prefrontal cortex

iScience
Summary: Positive emotions determine individual well-being and sustainable social relationships. Here, we examined the neural processes mediating upregulation of positive social emotions using functional magnetic resonance imaging in healthy female ...

Dual roles of Drosophila reward-encoding dopamine neurons in regulating innate and learned behaviors

iScience
Summary: Dopaminergic neurons (DANs) play a key role in learning the value of cues that predict reward. The fruit fly Drosophila has provided a powerful model to dissect the mechanisms by which reward-encoding DANs mediate reward learning.

Time-restricted feeding entrains long-term behavioral changes through the IGF2-KCC2 pathway

iScience, 2022
Summary: The suprachiasmatic nucleus (SCN) integrates light and systemic signals from peripheral tissues to coordinate physiology and behavior daily rhythms.

Dissociating neural circuits of social and prosocial reward in rat helping behavior

iScience
Summary: Helping behavior in rodents provides a powerful model for studying neurobiological underpinnings of prosocial motivation. Previously, rats allowed to release a trapped conspecific demonstrated prosocial motivation selectively toward ingroup ...

Phase-Coded Oscillatory Ordering Promotes the Separation of Closely Matched Representations to Optimize Perceptual Discrimination

iScience, 2020
Summary: Low-frequency oscillations are proposed to be involved in separating neuronal representations belonging to different items. Although item-specific neuronal activity was found to cluster on different oscillatory phases, the influence of this ...

Tracking spatial patterns and daily modulation of behavior in a natural population of the pulse-type weakly electric fish, Gymnotus omarorum

iScience
Summary: Tracking individual spatial and activity-rest patterns in natural populations is challenging because it is seldom possible to monitor individual-specific traits continuously.

Zebrafish sleep displays distinct sub-states

iScience
Summary: Sleep is an essential and evolutionarily conserved behavior. While mammals and several other species have been shown to exhibit well-defined sleep sub-states, it remains unclear to what extent such differentiation exists across the animal ...

Numerosity perception is tuned to salient environmental features

iScience, 2022
Summary: Numerosity perception is a key ability to guide behavior. However, current models propose that number units encode an abstract representation of numerosity regardless of the non-numerical attributes of the stimuli, suggesting rather coarse ...

Task-specific oscillatory synchronization of prefrontal cortex, nucleus reuniens, and hippocampus during working memory

iScience, 2023
Summary: Working memory requires maintenance of and executive control over task-relevant information on a timescale of seconds. Spatial working memory depends on interactions between hippocampus, for the representation of space, and prefrontal cortex ...

Bi-directional encoding of context-based odors and behavioral states by the nucleus of the lateral olfactory tract

iScience, 2021
Summary: The nucleus of the lateral olfactory tract (NLOT) is not only a part of the olfactory cortex that receives olfactory sensory inputs but also a part of the cortical amygdala, which regulates motivational behaviors.
