Individual differences in neural response to appetitive and aversive stimuli may confer vulnerability to stress-related psychopathology, including depression and anxiety. However, the specificity of this association with symptoms of depression and anxiety within the context of real world stress is not well understood. The present study examined whether neural responses to appetitive and aversive images, measured by the late positive potential (LPP), prospectively predict symptoms of depression and/or anxiety during the transition to university-a common, major life stressor-in 70 female emerging adults. A blunted LPP to appetitive stimuli at the start of the university year was uniquely associated with greater symptoms of depression six weeks later, after controlling for time one depressive symptoms and neural responses to aversive and neutral stimuli. These findings suggest that a blunted LPP to appetitive images may be biomarker of risk for developing symptoms of depression, and not anxiety, following life stress.

The theory that infectious agents, symbiotic microorganisms, and parasites are normal stimulants for the maturation of the immune system toward a balanced immune response. The theory predicts that lack of such stimulation leads to allergies and AUTOIMMUNE DISEASES.
An early embryonic developmental process of CHORDATES that is characterized by morphogenic movements of ECTODERM resulting in the formation of the NEURAL PLATE; the NEURAL CREST; and the NEURAL TUBE. Improper closure of the NEURAL GROOVE results in congenital NEURAL TUBE DEFECTS.
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. one without, radionuclide images using different radionuclides, radiograph vs. radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, coloring of vessels in angiograms).
The two longitudinal ridges along the PRIMITIVE STREAK appearing near the end of GASTRULATION during development of nervous system (NEURULATION). The ridges are formed by folding of NEURAL PLATE. Between the ridges is a neural groove which deepens as the fold become elevated. When the folds meet at midline, the groove becomes a closed tube, the NEURAL TUBE.
