Avoidance learning in autoimmune mice

Brain Research, 2000
Previous studies have shown that autoimmune mice perform very poorly on active avoidance learning tasks. In the current studies, mice with lupus-like systemic autoimmunity were able to learn active, as well as passive, avoidance protocols with shock as reinforcement.

Noradrenaline and avoidance learning in the rat

Brain Research, 1979
The selective neurotoxin 6-hydroxydopamine was used to deplete forebrain noradrenaline to less than 5% of control values and the learning capabilities of the depleted animals examined on a two-way active avoidance task. Noradrenaline depleted animals learned the two-way active avoidance task more quickly than controls and required fewer training trials

Learning to Avoid Extremism

Educational Theory, 2023
AbstractDemocracies are calling on schools to respond to a rise in extremist ideologies and actions. In this article Sigal Ben‐Porath situates the rise in extremism within the broader context of political polarization. She suggests that the latter is a more appropriate target for school intervention than the former. She further suggests that addressing

Forebrain serotonergic involvement in avoidance learning

Neuroscience Letters, 1985
The one-way active avoidance deficit caused by the serotonergic (5-HT) releasing compound p-chloroamphetamine (PCA) was examined in rats after degeneration of 5-HT neurons in the forebrain. Injection of 5,7-dihydroxytryptamine (5,7-DHT) into the forebrain in desipramine (20 mg/kg)-pretreated rats resulted in a 65-70% decrease in 5-HT concentrations in ...

The Avoidance Learning Problem

1972
Publisher Summary This chapter focuses on the avoidance learning problem. The first form the problem of avoidance learning took was quite unrecognizable. A human S's finger was placed on a metal electrode and after a 2-second conditioned stimulus (CS), or warning stimulus, electricity from an inductorium is applied. The unconditioned response (US) is

Hormones and Avoidance Learning

1975
Hormonal involvement in learning processes is most likley to take one of two forms. First, as the previous chapter has shown, hormones in the form of neurotransmitters could underlie the formation and maintenance of memory traces themselves and play a major role in the neural organization of information as well. Second, hormones can affect the learning
