Review The somatic marker hypothesis: A critical evaluation.

The somatic marker hypothesis as connected and related to the functions of working memory are also explained by Damasio (1999), who argues that ventral regions of pre frontal cortex support decision making based on somatic markers whereas as dorsal regions of the pre frontal cortex support working memory functions (Jameson, 2004 Toplak et al 2010 Damasio, 1996).

In contrast to economic theory, the somatic marker hypothesis proposes that emotions play a critical role in our ability to make fast, rational decisions in complex and uncertain situations. Patients with frontal lobe damage (e.g., Phineas Gage) provided the first evidence that the frontal lobes were associated with decision-making and social conduct.
