Purkinje cells translate subjective salience into readiness to act and choice performance

Abstract: In the originally published version of this article, Figure 5E contained a mistake in the explanation of the symbols, with the colored square erroneously labeled as "Fig. 6" as opposed to the correct "Fig.

“…The eyeblink reflex, for instance, is not just an isolated contraction of the eyelid muscles, but part of a defensive reflex involving the whole face, or maybe even the entire body [ 11 ]. These findings are in agreement with the notion of the cerebellum as a coordinating area for most, if not all, complex motor as well as non-motor functions [ 5 , 8 , 12 , 13 ].…”

“…Given the widespread projections, it is quite striking that most brainstem motor nuclei do not receive direct input from the cerebellum, or only sparse projections. This could be in line with modulatory and coordinating roles, rather than with direct motor control [ 12 ]. The study of these projections in diseases has just begun, but it is already clear that various diseases implicate variations in connectivity between the cerebellum and the rest of the brain.…”

“…Given that all dendrites of all olivary neurons are studded with GABAergic terminals ( De Zeeuw et al, 1989 , 1990a , b ; Ruigrok et al, 1990 ) and that all olivary subnuclei receive a GABAergic input ( Nelson et al, 1989 ), the finding of the excitatory MCN projection to the cdMAO raises the question what the source is of GABAergic input to the cdMAO. The combined inhibitory and excitatory input to dendritic spines in the IO facilitates its neurons to fine-tune the timing of its climbing fiber activity ( Loyola et al, 2023 ), allowing for precise control of online motor performance ( Welsh et al, 1995 ; Van Der Giessen et al, 2008 ; Hoogland et al, 2015 ) and long-term adjustments ( Gao et al, 2012 ; Kostadinov et al, 2019 ; Bina et al, 2022 ).…”

“…Activation of the climbing fiber terminals elicits both short-term and long-term effects ( De Zeeuw et al, 2011 ). In the short-term, it evokes powerful, all-or-none, depolarizations in Purkinje cells also known as complex spikes ( Thach, 1967 ); increases in complex spike activity within cerebellar microzones can facilitate reflex-like movements, such as fast reactive limb movements following a perturbation ( De Gruijl et al, 2014a ; Hoogland et al, 2015 ), but when occurring in more widespread ensembles they also mediate more demanding forms of motor behavior, such as skilled sequences of contractions of tongue muscles upon presentation of specific sensory cues ( Welsh et al, 1995 ; Bina et al, 2022 ; Romano et al, 2022 ). In the more long term, modulation of climbing fiber activity facilitates the induction of various forms of pre- and postsynaptic plasticity at most, if not all, parallel fiber synapses onto interneurons and Purkinje cells in the molecular layer of the cerebellar cortex ( Gao et al, 2012 ).…”

“…In the more long term, modulation of climbing fiber activity facilitates the induction of various forms of pre- and postsynaptic plasticity at most, if not all, parallel fiber synapses onto interneurons and Purkinje cells in the molecular layer of the cerebellar cortex ( Gao et al, 2012 ). Due to the fact that these different subcellular effects occur in a synergistic fashion in that they ultimately converge into either a downbound or upbound impact on simple spike activity in the Purkinje cells ( De Zeeuw, 2021 ), climbing fibers are also prominently implicated in cerebellar learning ( Ito and Kano, 1982 ; Raymond and Lisberger, 1998 ; Safo and Regehr, 2008 ; ten Brinke et al, 2015 and ten Brinke et al, 2019 ; Gutierrez-Castellanos et al, 2017 ; Boele et al, 2018 ; Bina et al, 2022 ; Romano et al, 2018 ). For both the short-term and long-term effects in the cerebellar cortex the precise timing of the climbing fiber activation is crucial.…”
