Spontaneous Alternation Behavior in Human Neutrophils

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...

The Impact of a Naturalistic Stressor on Spontaneous Alternation Behavior: A New Animal Model of OCD

Over the past few decades, various animal models of obsessive compulsive disorder (OCD) have been developed. Similarly, various stressors have been used throughout animal research. The Spontaneous Alternation Behavioral (SAB) model is a well-established model of OCD while 2,5-dihydro-2,4,5-trimethylthiazoline (TMT) has recently become a popular naturalistic stressor. This study linked the two t...

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...

The presence of home-cage stimuli attenuates spontaneous-alternation deficits in rats with septal lesions

The present experiment examined the effects of the olfactory context on spontaneousalternation performance of young adult, female rats following septal lesions. Separate groups of rats were given either septal lesions (n=24) or control surgery (n=24), and then tested on the 8th postoperative day for spontaneous alternation across three trials. Half of the rats in each surgical group were tested...
