Smell–taste dysfunctions in extreme weight/eating conditions: analysis of hormonal and psychological interactions
(Springer, 2016-02)
(1) The objective of this study is to analyze differences in smell–taste capacity between females in extreme weight/eating conditions (EWC) and (2) to explore the interaction between smell/taste capacity, gastric hormones, ...
Gray matter atrophy is associated with funcional connectivity reorganization during the Pasat Auditory Serial Addition Test (PASAT) execution in Multiple Sclerosis (MS)
(Elsevier, 2015-06)
Background and purpose:
We explored the relationship between gray matter atrophy and reorganization of functional connectivity in multiple sclerosis patients during execution of the Paced Auditory Serial Addition Test ...
Lower activation in the right frontoparietal network during a counting Stroop task in a cocaine-dependent group
(Elsevier, 2011)
Dysregulation in cognitive control networks may mediate core characteristics of drug addiction. Cocaine dependence has been particularly associated with lowactivation in the frontoparietal regions during conditions requiring ...
The sentence verification task: a reliable fMRI protocol for mapping receptive language in individual subjects
(Springer-Verlag, 2010)
To test the capacity of a sentence verification (SV) task to reliably activate receptive language areas. Presurgical evaluation of language is useful in predicting postsurgical deficits in patients who are candidates for ...
Frontostriatal response to set switching is moderated by reward sensitivity
(Oxford University Press, 2011)
The reinforcement sensitivity theory (RST) relates individual differences in reward sensitivity to the activation of the behavioral
approach system (BAS). Dopamine-related brain structures have been repeatedly associated ...
Reduced striatal volume in cocaine-dependent patients
(Elsevier, 2011)
Long-term cocaine consumption is associated with brain structural and functional changes. While the animal literature on cocaine use and dependence has traditionally focused on the striatum, previous human studies using ...
Dopaminergic modulation of effort-related choice behavior as assessed by a progressive ratio chow feeding choice task: pharmacological studies and the role of individual differences
(Public Library of Science, 2012)
Mesolimbic dopamine (DA) is involved in behavioral activation and effort-related processes. Rats with impaired DA
transmission reallocate their instrumental behavior away from food-reinforced tasks with high response ...
Prevención del VIH en diagnóstico de dependencia a la cocaína y trastorno esquizoafectivo
(Universidad Veracruzana. Instituto de Investigaciones Psicológicas, 2011-01)
Tras analizar brevemente la situación de los pacientes con diagnósticos múltiples e infección por VIH, en este trabajo se expone la actuación preventiva para la transmisión del VIH en un caso de un paciente portador con ...
Alpha-lipoic acid, a scavenging agent for H2O2, reduces ethanol-stimulated locomotion in mice
(Springer-Verlag, 2011-07-19)
Rationale
The main system of central ethanol oxidation is mediated by the enzyme catalase. By reacting with H2O2, brain catalase forms compound I (the catalase–H2O2 system), which is able to oxidize ethanol to acetaldehyde ...
Nucleus accumbens and effort-related functions: behavioral and neural markers of the interactions between adenosine A2A and dopamine D2 receptors
(Elsevier, 2010-04)
Nucleus accumbens dopamine (DA) is a critical component of the brain circuitry regulating work output in reinforcement-seeking behavior and effort-related choice behavior. Moreover, there is evidence of an interaction ...
