At this conference, a group of 30 neuroscientists constructed a syllabus outline delineating the scope of a neurochemistry curriculum appropriate for medical, graduate and postgraduate neuroscience students.
Out of this outline grew the first edition, edited by R. Wayne Albers, George J. Siegel, Robert Katzman and Bernard W. It was anticipated that the book would evolve with the emergence of the field and would stimulate continuing reappraisal of the scientific and educational aspects of neurochemistry.
Care has been taken to confirm the accuracy of the information presented and to describe generally accepted practices. However, the authors, editors, and publisher are not responsible for errors or omissions or for any consequences from application of the information in this book and make no warranty, express or implied, with respect to the contents of the publication.
The authors, editors, and publisher have exerted every effort to ensure that drug selection and dosage set forth in this text are in accordance with current recommendations and practice at the time of publication. However, in view of ongoing research, changes in government regulations, and the constant flow of information relating to drug therapy and drug reactions, the reader is urged to check the package insert for each drug for any change in indications and dosage and for added warnings and precautions.
This is particularly important when the recommended agent is a new or infrequently employed drug. Some drugs and medical devices presented in this publication have Food and Drug Administration FDA clearance for limited use in restricted research settings. Embed Size px.

Synapses are sites where various signal transduction pathways are activated including those of neurotransmitters NT; glutamate receptors linked to calcium inlux and receptors coupled to cAMP production are shown , and neurotrophic factors NTF. Synapses contain all the major organelles except the nucleus and proteins involved in apoptosis including Bcl-2 family members, p53, Par-4, mitochondria and ER, and caspases. Alterations in axonal transport may also trigger apoptosis.
