Researchers dissect the tick and tock of the human body's master clock

Article Abstract:

Researchers shared their experiences studying the suprachiasmatic nucleus (SCN) at a 1997 conference celebrating the 25th anniversary of the discovery of the SCN. This part of the hypothalamus in the brain is so-called because it is located above the optic chiasm. In 1967, a scientist reported that lesions in the hypothalamus abolished the biological clock in animals. The SCN was identified and linked to the biological clock in 1972. Researchers have since discovered many things about the SCN, including the fact that an SCN transplant will restore biological rhythms in animals with a non-functioning SCN. The resulting rhythm will match the rhythm of the donor.

New Medications Aid Cognition in Schizophrenia

Article Abstract:

The National Mental Health Administration is planning a nationwide media campaign to convince families and physicians of schizophrenics that the disease can be successfully treated and the patients can resume a normal life. This is partly due to new medications that do not have such severe side effects as older ones. They include Risperdal, Zyprexa, Clozaril, and Seroquel. Other drugs are in testing or awaiting approval by the FDA. However, studies have shown that many psychiatrists are not using these drugs as often as they could.
