Jan 15, 2016 · Scientists believe that emotions arose in higher organisms because they helped them survive. Problems with biological systems that regulate the emotions often have precisely the opposite effect: having major depression or chronic, acute anxiety makes daily survival that much more difficult.

For a long time, scientists thought individual emotions arose from specific regions of the brain: The amygdala was thought to be responsible for fear, for example. But as neuroscience techniques and insights advance, it has become clear that multiple networks of neurons and parts of the brain are active during each emotion.
Other influential scientists have promoted a different view on emotions, which does not imply consciousness as a prerequisite but rather as a feature that has evolved in higher species and was added on top of otherwise conserved primitive emotion processes [1,9,12, 13, 14]. Maybe the most important consequence of these views is whether or not animal research can, and if so to what extent ...
Jan 18, 2013 · Together, these findings indicate a key role of the brainstem in triggering and supporting emotion and feeling. Normal human feelings do not require the insula, although they consistently engage ...

Techniques available for studying the human brain do not allow precise localization of specific nuclei, though some progress is being made in this regard (Davis et al., 2011; Bach et al., 2011). An important question concerns the nature of the amygdala in non-mammals and the role of the homologous structure in fear conditioning.
Jan 3, 2024 · Emotions, intricate blends of mental and physical states, form a broad spectrum. They encompass everything from the elation of joy to the weight of sadness, the fervor of anger, the surge of fear, the jolt of surprise, and the aversion of disgust. These aren't just transient feelings; they're potent

Mar 1, 2005 · A detailed neuroscientific understanding of basic human emotions may depend critically on understanding comparable animal emotions. 1 As I have noted many times “As long as psychology and neuroscience remain more preoccupied with the human brain’s impressive cortico-cognitive systems than subcortical affective ones, our understanding of the sources of human consciousness will remain ...
