    Temporally Local Tactile Codes Can Be Stored in Working Memory
    with Arindam Bhattacharjee
    Frontiers in Human Neuroscience 16. 2022.
    Tactile exploration often involves sequential touches interspersed with stimulus-free durations. Whereas it is obvious that texture-related perceptual variables, irrespective of the encoding strategy, must be stored in memory for comparison, it is rather unclear which of those variables are held in memory. There are two established variables—“intensity” and “frequency”, which are “temporally global” variables because of the long stimulus integration interval required to average the signal or der…Read more

    Spatio-temporal constraints of the tidal wave theory
    Behavioral and Brain Sciences 20 (2): 264-265. 1997.
    The tidal-wave theory is inspired by the particular morphology of the cerebellar cortex. It elegantly attributes function to the anisotropy of the cerebellar wiring and the geometry of Purkinje cell dendrites. In this commentary, physiological considerations are used to elaborate temporal and spatial constraints of the tidal-wave theory. It is shown, first, that limitations of temporal precision in the cortical inputs to the mammalian cerebellum delimit the spatial resolution of an input sequenc…Read more
