Diurnal mood improvement was associated with activity of dorsal neural networks. Increased mean core temperature was also observed. One hypothesis proposed that depression was a result of a phase shift. [30] Daytime light exposure correlates with decreased serotonin transporter activity, which may underlie the seasonality of some depression. [31]
When stress successfully impacted the subjects, their neural activity showed reduced working memory related activity in the DLPFC. [42] These findings not only demonstrate the importance of the DLPFC region in relation to stress, but they also suggest that the DLPFC may play a role in other psychiatric disorders.
Some physiological changes also occurred including the decrease in body weight gain and adrenal hypertrophy observed in animals exposed to stress. Overall, the conditioned fear responses can contribute to behavioral changes in a repeated stress paradigm. This can be extended to correlate to other animals as well but with varying degrees of ...
Examples of cognitive research might involve examination of neural correlates during emotional information processing, such as one study that analyzed the relationship between subjective affect and neural reactivity during sustained processing of positive and negative emotion. The aim of the study was to analyze whether repetitive positive ...
This process is facilitated by the release of stress hormones and neurotransmitters, which modulate synaptic plasticity and enhance neural connectivity. [ 50 ] [ 51 ] [ 52 ] Multiple mechanisms have been proposed to explain this prioritized encoding, including the neuromodulatory effects on plasticity and the dynamic interplay between the ...

Another clinical study showed declines in depression, anxiety and suicidal ideation following a treatment program using AVE. [12] A study by Berg and Siever used audio-visual entrainment devices on women with seasonal affective disorder. Both depression and anxiety symptoms were reduced in participants, as compared to a placebo phase.
Italy’s former national carrier Alitalia has started procedures for the collective dismissal of its remaining 2,059 employees, its administrators told unions. The move comes as the successor to ...
