  • Fine‐scale somatotopic encoding in brain areas devoted to sensorimotor processing has recently been questioned by functional neuroimaging studies which suggested its absence within the hand area of the human primary motor cortex. We re‐examined this issue by addressing somatotopy both in terms of functional segregation and of cortical response preference using oxygenation‐sensitive magnetic resonance imaging at high spatial resolution. In a first step, spatial representations of self‐paced… CONTINUE READING
