A cross-maze task that can be acquired through either place or response learning was used
to examine the hypothesis that posttraining neurochemical manipulation of the …

▪ Abstract Although the mammalian basal ganglia have long been implicated in motor
behavior, it is generally recognized that the behavioral functions of this subcortical group of …

Involvement of the hippocampus and caudate nucleus in place and response learning was
examined by functionally inactivating these brain regions bilaterally with infusions of lidocaine…

These experiments investigated the effects, on memory, of injections of d-amphetamine (10
micrograms/0.5 microliter) administered into the amygdala, hippocampus, or caudate …

The present experiments were designed to examine the hypothesis that the mammalian
brain contains anatomically distinct memory systems. Rats with bilateral lesions of caudate …

The present study examined the effect of lesions of the caudate nucleus or fimbria–fornix on
the acquisition of two water maze tasks. In both tasks, two rubber balls with different visual …

A series of five experiments examined the differential mnemonic roles of the hippocampus
and caudate-putamen and the modulatory influence of the amygdala on hippocampal and …

While judgment has hitherto typically been viewed as a discrete decision process, we propose
that it be conceptualized instead as a continuous and dynamic process of reassessment …

Stress is a biologically significant factor shown to influence synaptic plasticity and memory
functioning in the hippocampus. This study examined the role of the amygdala, a brain …
