Serotonergic modulation of basolateral amygdala nucleus in the extinction of reward-driven learning: The role of 5-HT bioavailability and 5-HT1A receptor
(Elsevier Science, 2021)
Serotonin (5-HT) neurotransmission has been associated with reward-related behaviour. Moreover, the serotonergic system modulates the basolateral amygdala (BLA), a structure involved in reward encoding, and reward prediction ...
Dorsal striatum coding for the timely execution of action sequences
(Cold Spring Harbor Laboratory, 2021-11)
The automatic initiation of actions can be highly functional. But occasionally these actions cannot be withheld and are released at inappropriate times, impulsively. Striatal activity has been shown to participate in the ...
Short-term cross-sensitizion of need-free sugar intake by combining sodium depletion and hypertonic NaCl intake
(2016-12-01)
History of sodium depletion cross-sensitizes the effects of drugs of abuse. The objective of the present study was to find out if history of sodium depletion also cross-sensitizes a natural reward such as sugar intake in ...
A field study of spatial memory in green-backed firecrown hummingbirds (Sephanoides sephaniodes)
(BLACKWELL, 2006-08)
The foraging ecology of hummingbirds involves the exploitation of a high number of patchily distributed flowers. This scenario seems to have influenced capabilities related to learning and memory, which help to avoid ...
On the effect of aromatherapy with citrus fragrance in the therapy of major depressive disorder
(2014)
The effect of aromatherapy on the human central nervous system is a controversial issue in medical sciences. Here we present a hypothesis relating citrus fragrance aromatherapy with brain glucose homeostasis in Major ...
Pollination systems in Pogonieae (Orchidaceae: Vanilloideae): A hypothesis of evolution among reward and rewardless flowers
(ELSEVIER GMBH, URBAN & FISCHER VERLAGJENA, 2013-08-02)
The tribe Pogonieae of Vanilloideae (Orchidaceae) consists of six genera, including Pogoniopsis, a mycoheterotrophic taxon with morphological characteristics distinct from the remaining of the tribe. A hypothesis about the ...
Patterns of phenotypic selection for oil and nectar in Monttea aphylla (Plantaginaceae) in a geographic mosaic of interactions with pollinators
(Elsevier Gmbh, 2017-07)
Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...
Introjective Individuals Tend Toward Anhedonia: Self-Report and Experimental Evidence
(2018)
A broad line of research has conceptualized personality based on the interaction of two aspects: interpersonal relatedness and self-definition. This theoretical corpus understands these functions as two poles according to ...
Neural markers of social and monetary rewards in children with Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder
(Nature Publishing Group, 2016-07)
Recent theories of decision making propose a shared value-related brain mechanism for encoding monetary and social rewards. We tested this model in children with Attention-Deficit/Hyperactivity Disorder (ADHD), children ...
Brain stimulation and morphine reward deficits in dopamine D2 receptor-deficient mice
(Springer, 2005-10)
Rationale: The rewarding effects of lateral hypothalamic brain stimulation, various natural rewards, and several drugs of abuse are attenuated by D1 or D2 dopamine receptor (D1R or D2R) antagonists. Much of the evidence ...
