Losartan effects on neural activity as assessed by blood oxygenation dependent (BOLD) fMRI during the anticipation of social feedback.
Periodo de tiempo: 90 minutes to 105 minutes after treatment
|
The social incentive delay task provides subjects with trial-wise feedback on their performance (as assessed by reaction time).
Neural activity will be measured by functional magnetic resonance imaging (fMRI).
To examine effects of treatment during the anticipation of social feedback fMRI-based neural indices during the anticipation period will be compared between the losartan and the placebo treated group using a Generalized Linear Model approach.
The analysis will focus on brain systems that play an important role in the anticipation of reward and punishment (prefrontal cortex and subcortical regions, including the striatum)

Losartan effects on neural activity as assessed by blood oxygenation dependent (BOLD) fMRI during the consummation of social feedback.
Periodo de tiempo: 90 minutes to 105 minutes after treatment
|
The social incentive delay task provides subjects with trial-wise feedback on their performance (as assessed by reaction time).
Following each trial the feedback will be indicated by positive and negative social stimuli.
Neural activity will be measured by functional magnetic resonance imaging (fMRI).
To examine effects of treatment during the consummation of social feedback fMRI-based neural indices during the presentation of the feedback will be compared between the losartan and the placebo treated group using a Generalized Linear Model approach.
The analysis will focus on brain systems that play an important role in reward and punishment (prefrontal cortex and subcortical regions, including the striatum)

Effects of Losartan on arousal ratings of the stimuli presented during the fMRI-paradigm as assessed by 1-9 Likert scales
Periodo de tiempo: 150 minutes to 160 minutes after treatment
|
Following the fMRI assessment participants will be asked to rate the arousal of the stimuli presented during fMRI.
Arousal will be assessed on 1-9 Likert rating scales.
To examine effects of treatment on arousal ratings the losartan and placebo groups will be compared using Generalized Linear Model approach.

Effects of Losartan on valence ratings of the stimuli presented during the fMRI-paradigm as assessed by 1-9 Likert scales
Periodo de tiempo: 150 minutes to 160 minutes after treatment
|
Following the fMRI assessment participants will be asked to rate the valence of the stimuli presented during fMRI.
Valence will be assessed on 1-9 Likert rating scales.
To examine effects of treatment on valence ratings the losartan and placebo groups will be compared using Generalized Linear Model approach.

Effects of Losartan on intensity ratings of the stimuli presented during the fMRI-paradigm as assessed by 1-9 Likert scales
Periodo de tiempo: 150 minutes to 160 minutes after treatment
|
Following the fMRI assessment participants will be asked to rate the intensity of the stimuli presented during fMRI.
Intensity will be assessed on 1-9 Likert rating scales.
To examine effects of treatment on intensity ratings the losartan and placebo groups will be compared using Generalized Linear Model approach.

Effects of Losartan on likeability ratings of the stimuli presented during the fMRI-paradigm as assessed by 1-9 Likert scales
Periodo de tiempo: 150 minutes to 160 minutes after treatment
|
Following the fMRI assessment participants will be asked to rate the likeability of the stimuli presented during fMRI.
Likeability will be assessed on 1-9 Likert rating scales.
To examine effects of treatment on likeability ratings the losartan and placebo groups will be compared using Generalized Linear Model approach.
|
150 minutes to 160 minutes after treatment

|
Effects of Losartan on dislikeability ratings of the stimuli presented during the fMRI-paradigm as assessed by 1-9 Likert scales
Periodo de tiempo: 150 minutes to 160 minutes after treatment
|
Following the fMRI assessment participants will be asked to rate the dislikeability of the stimuli presented during fMRI.
Dislikeability will be assessed on 1-9 Likert rating scales.
To examine effects of treatment on dislikeability ratings the losartan and placebo groups will be compared using Generalized Linear Model approach.
