Abstract

The formation of the proper pattern of neuronal circuits during development is critical for the normal function of the vertebrate brain and for the survival of the organism. Circuit tracing studies spanning the past 100 years have revealed the beauty and exquisite intricacy of this pattern, which represents the most complex biological system known. In humans, aberrant circuit formation is a likely underlying cause of a wide variety of birth defects and neurological disorders, including autism, intellectual disability, and schizophrenia. Furthermore, future therapeutic approaches to restoring the function of damaged neural circuits will require a better understanding of the developmental constraints under which those circuits were originally assembled. For these reasons, elucidating the molecular mechanisms of neural circuit formation is a major goal of neurobiology today.

Abstract

Brain derived neurotophic factor (BDNF) and its receptor tropomyosin receptor kinase B (TrkB) signaling has been extensively studied for its roles in the central nervous system (CNS) ranging from cell survival, axonal and dendritic growth and synapse formation. Intracellular signaling pathways triggered by BDNF activate gene transcription, translation, post-translational functions, trafficking of key synaptic proteins, and synaptic release mechanism. BDNF-TrkB signaling mediates long-lasting activity-modulated synaptic changes on excitatory and inhibitory neurons and plays significant roles in circuit development and modulation. Furthermore, this pathway is critical for learning, memory, sensory processing and other cognitive functions, and is implicated in neurological and psychiatric diseases. In addition to BDNF, more recent studies have identified new “growth” factors that play important roles in the development, maturation and maintenance and modulation of synaptic function. However, details of the cytoplamic signaling systems downstream of these synaptogenic factors are often less understood than conventional neurotophin signaling. This e-Book has collected original studies and review articles that present cellular and molecular mechanisms concerning activity-dependent synapse formation and their implications for behavior and brain disorders. It is our hope that readers will perceive this volume as a showcase for diversity and complexity of synaptogenic growth factors, and will stimulate further studies in this field.
