    Mechanisms that allow cortical preparatory activity without inappropriate movement

    Timothy R Darlington, Stephen G Lisberger
    The use of preparatory activity in the smooth eye movement region of the frontal eye fields as a visual-motor gain signal allows preparation to progress without inappropriate movement.

    Transitioning between preparatory and precisely sequenced neuronal activity in production of a skilled behavior

    Vamsi K Daliparthi, Ryosuke O Tachibana ... Todd F Roberts
    Precisely sequenced patterns of neuronal activity associated with the production of a skilled behavior begin and end as part of orchestrated activity across functionally diverse populations of cortical premotor neurons.

    Muscarinic receptors mediate motivation via preparatory neural activity in humans

    John P Grogan, Matthias Raemaekers ... Sanjay G Manohar
    Muscarinic antagonism is causally involved in motivation and incentivisation in healthy human participants, partially mediated via preparatory neural signatures, with implications for cholinergic treatment of Parkinson's disease.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    Different contributions of preparatory activity in the basal ganglia and cerebellum for self-timing

    Jun Kunimatsu, Tomoki W Suzuki ... Masaki Tanaka
    Neuronal activity in the striatum keeps track of elapsed time during the time production task while that in the cerebellum correlates with stochastic variation of self-timing in the range of several hundreds of milliseconds.

    Conservation of preparatory neural events in monkey motor cortex regardless of how movement is initiated

    Antonio H Lara, Gamaleldin F Elsayed ... Mark M Churchland
    Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.
    1. Neuroscience

    Cerebellum encodes and influences the initiation, performance, and termination of discontinuous movements in mice

    Michael A Gaffield, Britton A Sauerbrei, Jason M Christie
    The activity of cerebellar Purkinje cells both represents and participates in organizing the temporal structure of a periodically performed motor action.

    Motor Networks: When preparation pays off

    Mark M Churchland
    Computational principles shed light on why movement is preceded by preparatory activity within the neural networks that control muscles.

    Preparation for upcoming attentional states in the hippocampus and medial prefrontal cortex

    Eren Günseli, Mariam Aly
    Memory guides attention by enabling preparation for upcoming states in the hippocampus and medial prefrontal cortex.
    1. Neuroscience

    Dynamic control of sequential retrieval speed in networks with heterogeneous learning rules

    Maxwell Gillett, Nicolas Brunel
    Low-dimensional external inputs are sufficient to control the speed of sequential activity, and to transition between persistent activity, in a network of neurons with both temporally symmetric and asymmetric learning.
