“…Anhedonia—the inability to experience pleasure (Ribot, 1896) and/or loss of interest—is a common symptom of many forms of psychiatric illnesses, including depression (APA, 2013; Gard et al, 2007; Lambert et al, 2018). At the neural level, anhedonia has been linked to deficits in the brain's ability to process and respond to appetitive cues in the environment (Harkness et al, 2022; Keedwell et al, 2005; Pizzagalli, 2014), and there is some evidence that deficits reflected in these neural measures can precede, and prospectively predict the onset of, depression (Bress et al, 2013; Freeman, Ethridge, et al, 2022; Freeman, Panier, et al, 2022; Kujawa et al, 2012, 2019; Kujawa, Proudfit, & Klein, 2014; Sandre et al, 2019). A large focus of my research has been on (a) identifying specific neural correlates of depression and/or anhedonia that might be useful in developing more precise clinical phenotypes, (b) understanding how variation in neural systems that process appetitive cues emerges, and finally (c) understanding how extremes of this variation might contribute to the emergence of psychopathology.…”
