Towards a possible aetiology for depressions?
Behavioral and Brain Functions - Tập 3 - Trang 1-7 - 2007
Since a genetic disposition for depression is probable, there ought to be biochemical changes. Increased peptide levels with relevant bioactivities have been found in urine in a previous investigation, which may be such changes. Urine from patients with severe depression according to ICD 10 have been run on reversed phase High Performance Liquid Chromatography, and off line mass spectrometry was p...... hiện toàn bộ
COMT Val158Met polymorphism, cognitive stability and cognitive flexibility: an experimental examinationAbstract
Background
Dopamine in prefrontal cortex (PFC) modulates core cognitive processes, notably working memory and executive control. Dopamine regulating genes and polymorphisms affecting PFC - including Catechol-O-Methyltransferase (COMT) Val158Met - are crucial to understanding the molecula... ... hiện toàn bộ

Evaluating the contribution of shape attributes to recognition using the minimal transient discrete cue protocol
Behavioral and Brain Functions - Tập 8 - Trang 1-14 - 2012
Subjects were tested for their ability to identify objects that were represented by an array of dots that marked the major contours, usually only the outer boundary. Each dot was briefly flashed to make its position known, and a major variable was the time interval that was required to flash all the dots for a given shape. Recognition declined as the total time for display of the dot inventory was...... hiện toàn bộ
Executive and motivational processes in adolescents with Attention-Deficit-Hyperactivity Disorder (ADHD)
Behavioral and Brain Functions - Tập 1 - Trang 1-12 - 2005
The objective of the current study was to examine performance and correlates of performance on a decision-making card task involving risky choices (Iowa Gambling Task) in adolescents with ADHD and comparison controls. Forty-four participants with ADHD and 34 controls were administered measures of estimated intellectual ability, working memory, and the card task. Also, behavioural ratings were obta...... hiện toàn bộ
Signatures of movement variability anticipate hand speed according to levels of intent
Behavioral and Brain Functions - - 2013
Complex movement sequences are composed of segments with different levels of functionality: intended segments towards a goal and segments that spontaneously occur largely beneath our awareness. It is not known if these spontaneously-occurring segments could be informative of the learning progression in naïve subjects trying to skillfully master a new sport routine. To address this question we aske...... hiện toàn bộ
The mystery of claustral neural circuits and recent updates on its role in neurodegenerative pathology
Behavioral and Brain Functions - - 2021
The claustrum is a structure involved in formation of several cortical and subcortical neural microcircuits which may be involved in such functions as conscious sensations and rewarding behavior. The claustrum is regarded as a multi-modal information processing network. Pathology of the claustrum is seen in certain neurological disorders. To date, there are not enough comprehensive studies that co...... hiện toàn bộ
Neural networks engaged in tactile object manipulation: patterns of expression among healthy individuals
Behavioral and Brain Functions - Tập 6 - Trang 1-17 - 2010
Somatosensory object discrimination has been shown to involve widespread cortical and subcortical structures in both cerebral hemispheres. In this study we aimed to identify the networks involved in tactile object manipulation by principal component analysis (PCA) of individual subjects. We expected to find more than one network. Seven healthy right-handed male volunteers (aged 22 to 44 yrs) manip...... hiện toàn bộ

Nicotine-induced brain metabolism associated with anger provocation
Behavioral and Brain Functions - Tập 5 - Trang 1-6 - 2009
Cortico-limbic brain activity associated with anger may be susceptible to nicotine and, thus, may contribute to smoking initiation and nicotine addiction. The purpose of the study was to identify the brain regions that are most reactive to nicotine and show the greatest association with anger task performance. Twenty adult nonsmokers (9 women, 11 men) participated in two laboratory sessions to ass...... hiện toàn bộ
