Dopaminergic and Non-Dopaminergic Value Systems in Conditioning and Outcome-Specific Revaluation [PDF]

open access: yes, 2007
Animals are motivated to choose environmental options that can best satisfy current needs. To explain such choices, this paper introduces the MOTIVATOR (Matching Objects To Internal Values Triggers Option Revaluations) neural model.

The elusive nature of the blocking effect: 15 failures to replicate [PDF]

open access: yes, 2016
With the discovery of the blocking effect, learning theory took a huge leap forward, because blocking provided a crucial clue that surprise is what drives learning.

Exclusive Breastfeeding Drives AMPK‐Dependent Thermogenic Memory in BAT and Promotes Long‐Term Metabolic Benefits in Offspring

open access: yesAdvanced Science, EarlyView.
Exclusive breastfeeding establishes a thermogenic memory in brown adipose tissue by activating the HIF1AN/AMPK/α‐ketoglutarate axis via milk‐derived extracellular vesicles enriched in miR‐125a‐5p. This programming preserves metabolic health, while αKG supplementation restores BAT function under mixed feeding, offering strategies to mitigate the ...

Discovery of a Novel and Potent Kir4.1 Inhibitor as a Safe and Rapid‐Onset Antidepressant Agent in Mice

open access: yesAdvanced Science, EarlyView.
The preferred derivative JX3212 demonstrates strong inhibitory activity against Kir4.1 with favorable druggability and shows significant antidepressant efficacy in vivo. Abstract Major depressive disorder is a serious psychiatric disorder for which novel and fast‐acting antidepressants are required.

Boldness and natural behaviors in the African lion (Panthera leo): How are they related? [PDF]

open access: yes, 2017
The African lion (Panthera leo) population is diminishing rapidly, approximately 43% since 1993 (Bauer et al., 2016. The species is currently listed as vulnerable by the IUCN (Bauer et al., 2016).

Effects of dietary fibre on behaviour and satiety in pigs [PDF]

open access: yes, 2008
During the past decades there has been considerable interest in the use of dietary fibre in both animal and human nutrition. In human subjects dietary fibre has been studied intensively for possible effects on body-weight management and health. In animal

Correlative Imaging Platform Linking Taste Cell Function to Molecular Identity

open access: yesAdvanced Science, EarlyView.
A correlative imaging platform is developed to study how individual taste cells respond to different taste qualities. By linking cellular activity with molecular identity and environmental context, dual‐tuned taste cells capable of detecting both sweet and umami stimuli are identified.

Conservation of the Lion: Preventing an Africa without the African Lion [PDF]

open access: yes, 2018
The African lion (Panthera leo) population is diminishing rapidly, approximately 43 percent since 1993. The species is currently listed as vulnerable by the International Union for Conservation of Nature (IUCN).

Corticosterone Regulates Both Naturally Occurring and Cocaine‐Induced Dopamine Signaling by Selectively Decreasing Dopamine Uptake [PDF]

open access: yes, 2017
Stressful and aversive events promote maladaptive reward‐seeking behaviors such as drug addiction by acting, in part, on the mesolimbic dopamine system. Using animal models, data from our laboratory and others show that stress and cocaine can interact to

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

open access: yesAdvanced Science, EarlyView.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...
