| Several articles detail aspects of physiology and function of neurotrophins and growth cone guidance in the development of vertebrate nervous systems. New evidence shows that while collapsin repulses some tips, called growth cones, it attracts others, says Tessier-Lavigne. Studies presented in this section relate to the plastic changes associated with normal and pathological amino acid receptor development and receptor roles in learning and memory, nerve cell-glial developmental interactions and speculation on these roles in pathogenesis, possible intercellular signaling events that may lead to Alzheimer's disease, neuronal growth cone changes during development, synaptic plasticity and behavioral relationships, and sensory intracortical processing. |
