Injecting Instructions into Premotor Cortex

Commentary: Injecting Instructions into Premotor Cortex

Premotor cortex mediates perceptual performance

Articulatory goals have long been proposed to mediate perception. Examples include direct realist and constructivist (analysis by synthesis) theories of speech perception. Although the activity in brain regions involved with action production has been shown to be present during action observation (Mirror Neuron System), the relationship of this activity to perceptual performance has not been cl...

Injecting uniformities into Peano arithmetic

We present a functional interpretation of Peano arithmetic that uses Gödel’s computable functionals and which systematically injects uniformities into the statements of finite-type arithmetic. As a consequence, some uniform boundedness principles (not necessarily set-theoretically true) are interpreted while maintaining unmoved the Π2-sentences of arithmetic. We explain why this interpretation ...

Mirror Neurons and Premotor cortex leakage

The mirror is one of the strangest and most magical of human inventions. We look out at the external world, and see ourselves staring back. Mirrors are so ubiquitous that – for most people it is difficult to imagine a house without several – one in the bathroom, one in the bedroom, maybe others dotted round various rooms. We wash ourselves and shave and brush our teeth under our own gaze. At on...

Functional differentiation of the premotor cortex

Lateralization of higher brain functions requires that a dominant hemisphere collects relevant information from both sides. The right dorsal premotor cortex (PMd), particularly implicated in visuomotor transformations, was hypothesized to be optimally located to converge visuospatial information from both hemispheres for goal-directed movement. This was assessed by probabilistic tractography an...
