The peripubertal elimination of axospinous synapses and dendritic spines in monkey prefrontal cortex suggests that this region undergoes substantial reorganization during late postnatal development. Understanding the functional impact of these maturational refinements requires knowledge of the specific presynaptic elements involved in these changes. Two(More)
Ethanol has been shown to suppress calcium uptake into depolarized synaptosomes, to reduce the durations of calcium spikes in cultured cells and to reduce calcium conductances in invertebrate neurons. Voltage-activated calcium channels therefore appear to be an important target of ethanol action. However, the interactions of ethanol with specific types of(More)
OBJECTIVE To determine amitriptyline's (AMI) efficacy in the acute treatment of adolescent major depressive disorder (MDD). METHOD Subjects aged 12 through 17 years meeting Research Diagnostic Criteria for MDD, diagnosed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS), participated in a 2-week placebo-washout(More)
In response to an applied tensile load, axons of cultured neurons exhibit a number of morphological responses. We designed and implemented a cell stretching device to study the cellular mechanisms governing these responses. Rat sensory neurons were seeded onto a flexible silicone substrate and imaged during substrate stretch. The positions of stationary(More)
It has been well-recognized that starvation in anorexia and bulimia nervosa causes endocrine disturbances. Such disturbances may help understand why many people with eating disorders cannot easily reverse their illness since people with eating disorders often enter a downward spiraling circle with malnutrition sustaining and perpetuating the desire for more(More)
