In the present study, the effects of transiently lowering central serotonin levels by means of acute tryptophan depletion on measures of cognitive flexibility were examined. Flexible behaviour was measured in an Eriksen flanker task, and cardiac and electro-cortical responses to errors and congruent and incongruent stimuli were measured. The depletion was successful in lowering tryptophan levels and, as expected, it did not affect subjective mood. Depletion did not affect performance and… Expand
Acute tryptophan depletion attenuates conscious appraisal of social emotional signals in healthy female volunteers
ATD attenuates the attractiveness of positive faces and the negative intensity of threatening faces, suggesting that serotonin contributes specifically to the appraisal of the social salience of both positive and negative salient social emotional cues. Expand
The role of serotonin in performance monitoring and cognitive control
A role for serotonin in performance monitoring may be to confer the value and especially the costs of future actions as well as to modulate how action errors relate to subsequent behavioral inhibition. Expand
Effects of acute tryptophan depletion on raphé functional connectivity in depression
Reducing serotonin function appears to alter coordination of these mood-related networks in specific, low frequency ranges, and specific low frequency BOLD fMRI signals can identify regions implicated in neural circuitry and may enable clinically-relevant interpretation of functional connectivity measures.

Drug-free patients with major depression show an increased electrophysiological response to valid and invalid feedback
It is suggested that depressed drug-free in-patients have an atypical rostral anterior cingulate response to feedback that is independent of feedback validity, and the notion that the behavioral responses of depressed individuals to negative feedback are context dependent is confirmed. Expand
Performance Monitoring in Depression: Behavioural and Neurophysiological Correlates of Feedback Processing
A large number of people in the Netherlands are affected by depression, and it is one of the leading causes of disability (WHO, 2011). Expand


Acute tryptophan depletion in healthy males attenuates phasic cardiac slowing but does not affect electro-cortical response to negative feedback
Cardiac responses appear to be more sensitive to changes in serotonin metabolism and appear to reflect different aspects of the feedback stimulus, and the phasic cardiac response appears to be an important measure that provides additional information about the impact of feedback stimuli and serotonergic functioning.

The effect of acute tryptophan depletion on the BOLD response during performance monitoring and response inhibition in healthy male volunteers
This study provides more evidence for the suggested role of 5-HT in performance monitoring and revealed that gender and personality traits are important variables to take into account for future research. Expand
Serotonin and cognitive flexibility: neuroimaging studies into the effect of acute tryptophan depletion in healthy volunteers.
Recent investigations into the effect of ATD on the Blood Oxygen Level Dependent response during tasks that require cognitive flexibility, in healthy volunteers are discussed. Expand
Acute Serotonin and Dopamine Depletion Improves Attentional Control: Findings from the Stroop Task
Investigation of the influence of brain monoamine function on Stroop task performance in healthy participants using the established methods of acute dietary serotonin, dopamine, and combined monoamine depletion suggests that reduced tonic dopamine or serotonin activity within specific neural circuits may play a critical role in attentional control. Expand
Acute tryptophan depletion improves performance and modulates the BOLD response during a Stroop task in healthy females
The present study showed that a temporary reduction of 5-HT improved Stroop performance and changed the underlying brain activation pattern in healthy female participants and replicated the previous finding that ATD modulated the BOLD response in the dorsomedial prefrontal cortex during tasks that require cognitive control. Expand
Effects of acute tryptophan depletion on executive function in healthy male volunteers
The improvement in simple motor speed/ attention following ATD is in keeping with the ascribed role of 5-HT in the cortex, however performance on tests of executive function is not robustly altered. Expand
Tryptophan depletion impairs memory consolidation but improves focussed attention in healthy young volunteers
Results indicate that serotonin is essential in the process of long-term memory consolidation, primarily in the first 30 min after acquisition, and that improvement of specific cognitive processes by lowered 5-HT function may be linked to the removal of inhibitory actions of 5- HT in the cortex. Expand
Acute tryptophan depletion reduces activation in the right hippocampus during encoding in an episodic memory task
Results show that serotonin is important in long term memory processes, and that serotonin acts on the encoding phase and not on the retrieval phase. Expand
Neural basis of abnormal response to negative feedback in unmedicated mood disorders
The extent to which the amygdala showed less activity during negative feedback correlated inversely with the behavioral tendency to reverse after misleading feedback, which was not present in the MDD group, who also failed to recruit the prefrontal cortex during behavioral reversal. Expand
Acute Tryptophan Depletion in Healthy Volunteers Enhances Punishment Prediction but Does not Affect Reward Prediction
The selective potentiation of punishment prediction concurs with recent theorizing, suggesting that central 5-HT carries a prediction error for future punishment, but not for future reward. Expand
