Research on the cerebellum yields rewards

Construction of complex memories via parallel distributed cortical–subcortical iterative integration

“…One proposal is that the cerebellum has a particular role in goal/reward learning, especially in novel situations. Cerebellum supports this function using trial-by-trial error-correction, similar to its contribution to motor learning [ 101 ] – here its involvement is akin to the interference reduction seen with more cognitive engrams. Situation (coupled with motivation) is a key element of goals.…”

Cortico-cerebellar interactions during goal-directed behavior

“…The cerebellum is classically thought to be involved in motor control. Recent evidence suggests that the cerebellar function is more expansive [5][6][7], including reward prediction [8][9][10][11][12], motor planning [13][14][15][16], and navigation [17]. New advances in neurophysiological methods and behavioral paradigms in rodents now allow a closer examination of cortico-cerebellar interactions during complex sensorimotor tasks.…”

Revisiting reward impairments in schizophrenia spectrum disorders: a systematic review and meta-analysis for neuroimaging findings

“…Recent evidence supported the extended role of the cerebellum, from motion to a wide range of cognitive processes (such as learning, attention, emotion) (Brady et al, 2019; Schmahmann & Caplan, 2006). According to the ‘internal model’ (Ito, 2008; Wolpert, Miall, & Kawato, 1998), the basic function of cerebellar cortex is to monitor internal and external signals, construct internal models to predict potential consequences, and to update such models based on predictive errors (Raymond, 2020; Schmahmann, 2019). The cerebellum may be involved in reward processing and learning in a similar way (Carta, Chen, Schott, Dorizan, & Khodakhah, 2019; Raymond, 2020) via its connection with the basal ganglia and the prefrontal lobe (Bostan, Dum, & Strick, 2013; Bostan & Strick, 2018).…”
