Tracer studies of pyrimidine synthesis by Neurospora crassa 1298.
Previous reports from thii laboratory have described the growth-supporting abilities of a-aminobutyric acid, propionic acid, and certain related compounds for the pyrimidmelessstrain, Neurospora crassu 1298 (1, 2). Tracer studies with aminobutyric acid-3-Cl4 indicated the use of this compound by the mold as a precursor of the pyrimidines of the ribonucleic acids (3). This conclusion, however, w...

The developing forebrain roof plate (RP) contains a transient signaling center, perturbations in which have been linked to holoprosencephaly (HPE). Here, we describe a novel domain of retinoic acid (RA) signaling that is specific to the chick RP and demonstrate that RA signaling is sufficient for inducing characteristics of the RP in ectopic locations. We further demonstrate that, unlike what h...

In this study, we assess the impact of normal aging on top-down modulation, a cognitive control mechanism that supports both attention and memory by the suppression and enhancement of sensory processing in accordance with task goals. Using fMRI (functional magnetic resonance imaging), we show that healthy older adults demonstrated a prominent deficit in the suppression of cortical activity asso...
