What term describes feelings such as happiness, anger, or grief, created by brain patterns and accompanied by bodily changes?

The term that describes feelings such as happiness, anger, or grief, created by brain patterns and accompanied by bodily changes is "emotions." Emotions are complex psychological states that involve an experiential component, a physiological response, and a behavioral or expressive response. When we experience emotions, our brain triggers specific patterns that lead to sensations affecting our bodies, such as increased heart rate or changes in facial expressions.

While sentiments refer to more stable and enduring feelings or attitudes that can arise from emotional experiences, they do not capture the immediate and physiological aspects of feelings. Affections can describe a fondness or liking but are broader and often milder than the intense experiences characterized by emotions. Reactions could refer to responses to various stimuli, but they are not specifically tied to the complex interplay of feelings and physical responses that emotions encompass. Thus, "emotions" is the most accurate term to describe this phenomenon.
