Neurofeedback and quantitative electroencephalography.

This study was conducted in an attempt to determine the efficacy of neurofeedback (NFB) in the treatment of patients suffering from vertigo or tinnitus. Results indicated that after NFB, power for delta and theta bands was reduced; however, an increase of power was noted for the alpha bands. Furthermore, normalization was observed for the vestibular evoked potentials (VestEP).

A targeted thyroid hormone receptor alpha gene dominant-negative mutation (P398H) selectively impairs gene expression in differentiated embryonic stem cells.

Thyroid hormone and retinoic acid (RA) are essential for normal neural development in vivo, yet all in vitro differentiation strategies of embryonic stem (ES) cells use only RA. We developed a novel differentiation strategy of mouse ES cells using T(3). A dominant-negative knock-in point mutation (P398H) was introduced into the thyroid hormone receptor alpha gene to determine the influence of T(3) on ES cell differentiation.
