Brain activity during expectancy of emotional stimuli: an fMRI study.

abstract：:Perception of apparent motion operates somewhat differently for objects and human figures. Depending on the interstimulus interval, the latter d may give rise to either perception of a direct path (i.e. biologically impossible) or indirect path (i.e. biologically possible). Here, PET was used to investigate whether a ...

Exposure of 9-11-day-old primary cultures of rat cerebellar granule neurones for 3 h to a more depolarizing medium (additional 15-30 mM KCl) stimulated the release of glutamate and increased the BDNF mRNAs levels. This BDNF a...
