GABAA receptor-expressing neurons promote consumption in Drosophila melanogaster. [PDF]

PLoS ONE, 2017
Feeding decisions are highly plastic and bidirectionally regulated by neurons that either promote or inhibit feeding. In Drosophila melanogaster, recent studies have identified four GABAergic interneurons that act as critical brakes to prevent incessant ...

Parallel encoding of sensory history and behavioral preference during Caenorhabditis elegans olfactory learning

eLife, 2016
Sensory experience modifies behavior through both associative and non-associative learning. In Caenorhabditis elegans, pairing odor with food deprivation results in aversive olfactory learning, and pairing odor with food results in appetitive learning ...

Effects of environmental enrichment upon ethanol-induced conditioned place preference and pre-frontal BDNF levels in adolescent and adult mice [PDF]

, 2017
Environmental enrichment (EE) provides a non-pharmacological tool to alter drug-induced reward, yet its effects on ethanol-induced reward remain controversial. We analyzed adolescent vs.

Roles of Octopamine and Dopamine Neurons for Mediating Appetitive and Aversive Signals in Pavlovian Conditioning in Crickets

Frontiers in Physiology, 2017
Revealing neural systems that mediate appetite and aversive signals in associative learning is critical for understanding the brain mechanisms controlling adaptive behavior in animals.

Distinct patterns of outcome valuation and amygdala-prefrontal cortex synaptic remodeling in adolescence and adulthood. [PDF]

, 2015
Adolescent behavior is typified by increased risk-taking, reward- and novelty-seeking, as well as an augmented need for social and environmental stimulation.

Complex motivated behaviors for natural rewards following a binge-like regimen of morphine administration: mixed phenotypes of anhedonia and craving after short-term withdrawal

Frontiers in Behavioral Neuroscience, 2014
The anhedonia-like behaviors following about one-week withdrawal from morphine were examined in the present study. Male rats were pretreated with either a binge-like morphine paradigm or daily saline injection for 5 days.

Acetaldehyde involvement in ethanol's postabsortive effects during early ontogeny [PDF]

, 2013
Clinical and biomedical studies sustains the notion that early ontogeny is a vulnerable window to the impact of alcohol. Experiences with the drug during these stages increase latter disposition to prefer, use or abuse ethanol.

Combat high or traumatic stress: violent offending is associated with appetitive aggression but not with symptoms of traumatic stress

Frontiers in Psychology, 2015
Former members of armed groups in eastern DRCongo had typically witnessed, experienced and perpetrated extreme forms of violence. Enhanced trauma-related symptoms had been shown in prior research.
