Genome-wide recruitment of Mediator and Pol II is reduced in yeast lacking the Med2-Med3-Med15 tail module triad, and Mediator association with gene promoters depends on Pol II, Taf1, and TBP.
Both bottom-up and top-down processing are involved in the occipital-temporal face network, with the top-down modulation more extensively engaged when available information is sparse in the face images.
The protofilaments that curl outward from a disassembling microtubule tip carry a large amount of strain energy and they can drive movement with an efficiency similar to conventional motor proteins.
A set of tools to image and track growing plant roots in optimized growing conditions within a vertical stage confocal microscope will open up new possibilities in research of root development.
Neural spiking responses in the visual cortex carry both an explicit representation of the presence of a face and a late-arriving, explicit encoding of errors in face estimation.
