studies on the brain and emotions

The technique offers a comprehensive range of feature extraction and analysis methods, including power spectral analysis, EEG coherence, phase delay, and cross-power analysis. 67, 219–234. (2014). doi: 10.1016/j.neuropsychologia.2007.06.015, Barbey, A. K., Koenigs, M., and Grafman, J. (1999) reported increased gamma potentials in the left frontal and temporal regions in response to images having a negative valence, whereas increased gamma-bands in the right frontal regions were observed in responses to images with positive valence for 11 right-handed male participants. How emotions affect logical reasoning: evidence from experiments with mood-manipulated participants, spider phobics, and people with exam anxiety. Numerous studies have reported that human cognitive processes are affected by emotions, including attention (Vuilleumier, 2005), learning and memory (Phelps, 2004; Um et al., 2012), reasoning (Jung et al., 2014), and problem-solving (Isen et al., 1987). (2012) investigated the effects of emotional content on explicit verbal memory by assessing recall and recognition for emotionally positive, negative and neutral words. Clinically relevant studies of the minded brain. 8, 38. These results imply that (i) subcortical regions associated with emotion/motivation involved in hunger that signals distressing feeling (discomfort, pain and anxiety) for the regulation of food intake; and (ii) the PFC associated with inhibition of inappropriate behavioral response involved in satiation that signals excessive food consumption for a termination of meal. Neurosci. During an emotionally positive experience, another study reported significantly increased EEG theta-alpha coherence between prefrontal and posterior parietal regions (Aftanas and Golocheikine, 2001). Feelings are not commonly caused emotions. J. Psychophysiol. Hence, this direction of additional attention to emotional information appears to enhance LTM with the pronounced effects deriving from positive emotions compared with negative emotions. Persistent activity in the prefrontal cortex during working memory. In contrast, feelings refer to mental experiences that are necessarily valence, either good or bad as well as accompanied by internal physiological changes in the body, specifically the viscera, including the heart, lungs, and gut, for maintaining or restoring homeostatic balances. Another study reported greater alpha activity in the left frontal region (less left frontal alpha power) was associated with approach motivation, while the greater alpha activity in right frontal (less right frontal alpha power) was associated with withdrawal motivation (Harmon-Jones et al., 2010). Therefore, clarifying whether emotional stimuli enhance recognition memory or recall memory requires further investigation, as it appears that emotional information was better remembered for recognition compared to recall.

This is followed by the emotional-cognitive interactions in the various brain regions that are intimately involved in emotion and memory systems. Fundamentally, primary emotional processes regulate unconditioned emotional actions that anticipate survival needs and consequently guide secondary process via associative learning mechanisms (classical/Pavlovian and instrumental/operant conditioning). Clin. The results revealed a significantly greater increase in oxy-HB in the mPFC and left superior frontal gyrus in response to negative pictures compared with neutral pictures. Appropriate screening with psychological testing as well as balancing experimental cohorts in terms of sex can help reduce spurious results owing to individual differences. doi: 10.1016/j.pain.2010.12.037, Grimshaw, G. M., and Carmel, D. (2014). Oonishi, S., Hori, S., Hoshi, Y., and Seiyama, A. Neuropsychologia 37, 677–683. Brain Mapp. U.S.A. 93, 13508–13514. Anderson, L., and Shimamura, A. P. (2005). Studies in psychology (Metcalfe and Mischel, 1999) and neuroscience (Dolcos et al., 2011) proposed that cognition and emotion processes are operated at two separate but interacting systems: (i) the “cool cognitive system” is hippocampus-based that is associated with emotionally neutral cognitive functions as well as cognitive controls; and (ii) the “hot emotional system” is amygdala-based that responsible for emotional processing and responses toward unconditioned emotional stimuli such as appetitive and fear-evoking conditions. doi: 10.1016/j.neubiorev.2011.08.003, Panksepp, J. Some studies report that positive emotions facilitate learning and contribute to academic achievement, being mediated by the levels of self-motivation and satisfaction with learning materials (Um et al., 2012). doi: 10.1016/j.cub.2015.05.052, Joëls, M., Karst, H., Alfarez, D., Heine, V. M., Qin, Y., Riel, E. V., et al. Hence, emotion is not a simple linear event but rather a feedback process that autonomously restores an individual’s state of equilibrium. Homeostatic affects, such as hunger and thirst, are not considered prototype emotional states. doi: 10.1038/nn1190, Richter-Levin, G., and Akirav, I. Discrete emotions or dimensions? doi: 10.1162/jocn.2009.21366, Wager, T. D., Davidson, M. L., Hughes, B. L., Lindquist, M. A., and Ochsner, K. N. (2008). Neuroscientist 11, 288–293. Brain Cogn. Also, witnessing facts and events of others’ life sometimes prompts inner reactions related to the beliefs, intentions, and desires of actors.”. J. Clin. Cortex 10, 284–294. One thing is clear though — emotions arise from activity in distinct regions of the brain. On the role of asymmetric frontal cortical activity in approach and withdrawal motivation: an updated review of the evidence. The distinction between emotion and homeostasis, is the process of regulation for continuously changing internal states via appropriate corrective responses that respond to both internal and external environmental conditions to maintain an optimal physiological state in the body. 25, R621–R634. The orbitofrontal cortex and reward. Neurosci. Behav. Environmental factors, ethical issues, memory paradigms, cognitive task difficulty, and emotional induction task intensity must be considered for this. doi: 10.1016/j.learninstruc.2012.05.003, Dael, N., Mortillaro, M., and Scherer, K. R. (2012). Humanit. (2014). Impact Factor 2.067 | CiteScore 3.2More on impact ›. The neurobiology of emotion–cognition interactions: fundamental questions and strategies for future research. To emphasize, depression and anxiety are the two most commonly diagnosed psychiatric disorders associated with learning/memory impairment and pose negative consequences that (i) limit the total amount of information that can otherwise be learned, and (ii) inhibit immediate recall as well as memory retention and retrieval of newly learned information.
