Abstract  This symposium took place at Trolleholm Castle near Lund on May 27–28, 2011. The meeting was a celebration of the lifetime achievements of Carl‐Fredrik Ekerot, who is now retired. The meeting drew together participants from many different disciplines of motor systems neuroscience, but with a focus on the cerebellum and the spinocerebellar systems, which was the main field of interest of Carl‐Fredrik Ekerot. Ekerot pioneered the field of climbing fibre microzones in the forelimb area of the C3 zone (Ekerot & Larson, 1980; Ekerot et al., 1991) and the role of the microzones as a functional unit in the cerebellar cortex and in the cerebellar nuclei (Garwicz & Ekerot, 1994; Ekerot et al., 1995), provided early evidence of the congruence between mossy fibre and climbing fibre inputs in the cerebellar cortex (Ekerot & Larson, 1973, 1980; Garwicz et al., 1998), made important contributions to the early days of cerebellar plasticity research centred on the classical climbing‐fibre dependent LTD of parallel fibre synapses on Purkinje cells (Ekerot & Kano, 1985, 1989), later discovered of several new forms of plasticity between the parallel fibres and the interneurons and Purkinje cells (Ekerot & Jorntell, 2001; Jorntell & Ekerot, 2002) and made a unique and detailed series of studies on the spinal and motor information processed by the cells of the lateral reticular nucleus (Clendenin et al., 1974a; Clendenin et al., 1974c, b; Ekerot, 1990c, b, a), an important source of mossy fibres to the cerebellum.
