Neuronal synchronization in human posterior parietal cortex during reach planning.
Although single-unit studies in monkeys have identified effector-related regions in the posterior parietal cortex (PPC) during saccade and reach planning, the degree of effector specificity of corresponding human regions, as established by recordings of the blood oxygen level-dependent signal, is still under debate. Here, we addressed this issue from a different perspective, by studying the neu...
متن کاملTemporal analysis of reference frames in parietal cortex area 5d during reach planning.
The neural encoding of spatial and postural reference frames in posterior parietal cortex has traditionally been studied during fixed epochs, but the temporal evolution of these representations (or lack thereof) can provide insight into the underlying computations and functions of this region. Here we present single-unit data recorded from two rhesus macaques during a reach planning task. We fo...
متن کاملRunning head: PARIETAL-MOTOR INTERACTION DURING REACH
24 Neural interactions between parietal area 2/5 and primary motor cortex (M1) were 25 examined to determine the timing and behavioral correlates of cortico-cortical interactions. 26 Neural activity in areas 2/5 and M1 was simultaneously recorded using 96-channel 27 microelectrode arrays in three rhesus monkeys performing a center-out reach task. We introduce 28 a new method to reveal parietal-...

متن کاملCoding of the Reach Vector in Parietal Area 5d
Competing models of sensorimotor computation predict different topological constraints in the brain. Some models propose population coding of particular reference frames in anatomically distinct nodes, whereas others require no such dedicated subpopulations and instead predict that regions will simultaneously code in multiple, intermediate, reference frames. Current empirical evidence is confli...
