    Bidirectional encoding of motion contrast in the mouse superior colliculus

    Jad Barchini et al.
    Two photon calcium imaging experiments show that excitatory and inhibitory neurons in the mouse superior colliculus are differentially modulated by the motion contrast between stimulus center and surround.

    The sifting of visual information in the superior colliculus

    Kyu Hyun Lee et al.
    The superior colliculus reveals hallmarks of sophisticated visual computation, including selectivity, invariance, and stimulus-specific habituation to behaviorally relevant stimuli.

    Attention-related modulation of caudate neurons depends on superior colliculus activity

    James P Herman et al.
    The pattern of spatial attention preferences in caudate neurons is altered by superior colliculus inactivation, demonstrating that a superior colliculus to basal ganglia link is important for selective attention.

    A projection specific logic to sampling visual inputs in mouse superior colliculus

    Katja Reinhard et al.
    Transsynaptic viral tracing reveals that neurons in the superior colliculus employ projection specific rules to the sampling of retinal inputs, directing distinct visual features to different downstream targets.

    Emergence of visually-evoked reward expectation signals in dopamine neurons via the superior colliculus in V1 lesioned monkeys

    Norihiro Takakuwa et al.
    The subcortical visual pathway through the midbrain superior colliculus is responsible for visually evoked Pavlovian conditioning and dopamine neuron responses with predicted value in monkeys, which remained after lesioning V1.

    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.

    Dynamic representation of 3D auditory space in the midbrain of the free-flying echolocating bat

    Ninad B Kothari et al.
    Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.

    Echolocation: Smart bats click twice

    Manfred Kössl, Julio Hechavarría
    The acoustic representation of the outside world in the midbrain of a bat becomes more precise as it uses double clicks to locate closer objects.

    New insights on the modeling of the molecular mechanisms underlying neural maps alignment in the midbrain

    Elise Laura Savier et al.
    A dominant sensory map provides positional information through correlated activity and transposed molecular cues to guide secondary sensory projections for alignment and organization.

    Revealing a novel nociceptive network that links the subthalamic nucleus to pain processing

    Arnaud Pautrat et al.
    The subthalamic nucleus is linked to a nociceptive network and involved in nociceptive processing and perception.
