Millimeter scale somatotopic mapping with TMS

MEG and TMS combined with EEG for mapping alcohol effects.

Magnetoencephalography (MEG) is a noninvasive method of studying magnetic fields from outside the skull that are generated by at least partially synchronized neuronal populations in the brain. The advantage of MEG over electroencephalography (EEG) is the transparency of the skull, scalp, and brain tissue to the magnetic fields, which facilitates easy localization of the cortical activity. In ME...

A pilot study of somatotopic mapping after cortical infarct.

BACKGROUND AND PURPOSE Animal studies have described remodeling of sensory and motor representational maps after cortical infarct. These changes may contribute to return of function after stroke. METHODS Functional MRI was used to compare sensory and motor maps obtained in 35 normal control subjects with results from 2 patients with good recovery 6 months after a cortical stroke. RESULTS Du...

Millimeter Range Forces in Superstring Theories with Weak - Scale Compactification

We show that theories, in which supersymmetry is broken via Scherk-Schwarz com-pactification at the weak scale, possess at least one scalar particle with Compton wavelength in the millimeter range which mediates a force with strength 1/3 of gravity. Such forces are going to be explored in upcoming experiments using micro-electromechanical systems or cantilever technology. We also present a simp...

Millimeter Scale Microrobots for the Nanoassembly Applications

Current top down manipulation systems used in micro and nanomanufacturing are many orders of magnitude larger than the parts being handled, leading to difficult tradeoffs between their precision, throughput and cost. This paper presents recent research progress in the manufacturing of millimeter sized robotic positioning technology that allows combining high precision with high throughput along...
