Acetylcholine Regulates Olfactory Perceptual Learning through Effects on Adult Neurogenesis

iScience, 2019
Summary: Learning to perceptually discriminate between chemical signals in the environment (olfactory perceptual learning [OPL]) is critical for survival.

Descending pathways increase sensory neural response heterogeneity to facilitate decoding and behavior

iScience, 2023
Summary: The functional role of heterogeneous spiking responses of otherwise similarly tuned neurons to stimulation, which has been observed ubiquitously, remains unclear to date.

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 ...

Corticosterone antagonist or TrkB agonist attenuates schizophrenia-like behavior in a mouse model combining Bdnf-e6 deficiency and developmental stress

iScience, 2022
Summary: While schizophrenia pathogenesis involves both genetic and environmental factors, their specific combinations remain ill-defined. Here we show that deficiency in promoter VI-driven BDNF expression, combined with early-life adversity, results in ...

Precise Quantification of Behavioral Individuality From 80 Million Decisions Across 183,000 Flies

, 2022
Individual animals behave differently from each other. This variability is a component of personality and arises even when genetics and environment are held constant.

Higher oxytocin concentrations occur in subjects who build affiliative relationships with companion robots

iScience, 2023
Summary: Building affiliative relationships with others is important for mental health. Recently, robots have been expected to play a role in improving mental health, but there is little scientific evidence as to whether they can build affiliative ...

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 ...

Drosophila Aversive Behavior toward Erwinia carotovora carotovora Is Mediated by Bitter Neurons and Leukokinin

iScience, 2020
Summary: The phytopathogen Erwinia carotovora carotovora (Ecc) has been used successfully to decipher some of the mechanisms that regulate the interactions between Drosophila melanogaster and bacteria, mostly following forced association between the two ...

Neuroscience of Behavior

NeuroSci
Behavior is not a mere sequence of responses to stimuli but the dynamic expression of internal processes such as planning, prediction, valuation, and inference. These functions arise from distributed and metabolically costly neural systems and are best understood by considering behavior and neural activity together.
