Redirected growth of the optic tract in hamsters with lesions of the midbrain tectum at birth
results in anomalous retinal projections with correlated functional effects; these include a …

Early developmental manipulations can induce sensory afferents of one modality to project
to central targets of a different sensory modal@. We and other investigators have used such …

The bold and thrilling quest to finally understand the brain We know that each of us is
unique, but science has struggled to pinpoint where, precisely, our uniqueness resides. Is it …

The growth of corticospinal axons into the spinal cord has been demonstrated using the
autoradiographic and the Fink‐Heimer silver degeneration methods. In addition, the …

Recent studies on neural pathways in a broad spectrum of vertebrates suggest that, in
addition to migration and an increase in the number of certain select neurons, a significant …

When pyramidal tract axons are cut in the adult hamster, fibers degenerate in both
anterograde and retrograde directions from the lesion. If the same operation is performed on …

These experiments investigate the capacity of thalamic and cortical structures in a sensory
system to process information of a modality normally associated with another system …

In the Syrian hamster, there is a delay between the laying down of the trajectory of the optic
tract (principally a prenatal event) and the formation by the optic tract of its various dense …

Rats received a midthoracic spinal cord “overhemisection” including right hemicord and left
dorsal funiculus at birth (neonatal operates, N= 15) or 21 days of age (weanling operates …

The restoration of connections in the injured central nervous system (CNS) of adult
mammals is hindered by the failure of axons to grow back to their natural fields of …
