Attention is central to many functions such as vision, emotion, reward, working memory and access awareness. However, it is not clear how attention interacts with emotion and how to separate them. We report that (1) Visual attention is a (reentrant) neural signal that enhances the feed-forward stimulus-related signal by modulating it. (2) Emotion is feeling related affective subjective...
Molecular neurobiology has provided an explanation of mechanisms supporting mental functions as learning, memory, emotion and consciousness. However, an explanatory gap remains between two levels of description: molecular mechanisms determining cellular and tissue functions, and cognitive functions. In this paper we review molecular and cellular mechanisms that determine brain activity, and...
