Investigation of mindfulness meditation practitioners with voxel-based morphometry.
MRI brain images of 20 mindfulness (Vipassana) meditators are investigated and meditation practice is associated with structural differences in regions that are typically activated during meditation and in areas that are relevant for the task of meditation.
Psychobiology of altered states of consciousness.
The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes.
Symptom provocation and reduction in patients suffering from spider phobia
It is concluded that successful treatment of spider phobia is primarily accompanied by functional changes of the medial OFC, which is crucial for the self-regulation of emotions and the relearning of stimulus-reinforcement associations.
Fear and the startle reflex: blink modulation and autonomic response patterns in animal and mutilation fearful subjects.
Exposure to pictures of feared objects resulted in a consistent startle reflex potentiation and behavioral avoidance in both fear groups, suggesting that the probe startle response indexes the organism's basic motivational disposition and add new information to the assessment of fear.
Neural activations of the acquisition of conditioned sexual arousal: effects of contingency awareness and sex.
The increased activity in men is in line with theories postulating that men are generally more prone to conditioning of sexual arousal and contingency awareness seems to be an important factor in appetitive learning processes, which facilitates conditioning processes.
