A Maturation Factor in Spontaneous Alternation

Spontaneous Alternation Behavior in Human Neutrophils

Apoptotic protease-activating factor 1 (Apaf-1) as a liable gene for spontaneous mutations in vitro

The apoptotic protease-activating factor 1 (Apaf-1) receives the death signal in the intrinsic ormitochondrial pathway of apoptosis. Upon the releasing of cytochrome c from theintermembrane space of mitochondria and binding to Apaf-1 molecules, a heptamericapoptosome complex is formed and triggers the downstream cascade of caspases. Here, for thefirst time we present spontaneous mutations and r...

Spontaneous alternation in marine crabs: invasive versus native species.

Organisms ranging from paramecia to humans tend to explore places that have been least recently explored, which is referred to as spontaneous alternation. Although organisms rely on different sources of information in alternating between places, the emergent behavioral pattern is likely advantageous during exploration and foraging. Under this rationale, continuous spontaneous alternation perfor...

Maturation of spontaneous arousals in healthy infants.

OBJECTIVE The propensity to arouse from sleep is an integrative part of the sleep structure and can have direct implications in various clinical conditions. This study was conducted to evaluate the maturation of spontaneous arousals during the first year of life in healthy infants. DESIGN Nineteen infants were studied with nighttime polysomnography on 3 occasions: aged 2 to 3 months, 5 to 6 m...

The role of extramaze cues in spontaneous alternation in a plus-maze.

Performance on various spatial tasks is superior in the presence of extramaze cues that provide guidance in locating the goal. This study was an investigation of the effect of such cues on nonrewarded, continuous spontaneous alternation in a plus-maze, a spatial task with no explicit reinforcement. Rats were tested in five daily sessions. Alternation scores, which reflect how frequently the lea...
