Research has shown that animal-assisted activities have specific benefits for older adults, such as decreasing loneliness (Banks & Banks, 2002; Banks, Willoughby, & Banks, 2008; Calvert, 1989) and depression (Grubbs, Artese, Schmitt, Cormier, & Panton, 2016; Le Roux & Kemp, 2009; Moretti et al., 2010) while increasing positive…

Uncontrollable stress has been recognized to influence the hippocampus at various levels of analysis. Behaviorally, human and animal studies have found that stress generally impairs various hippocampal-dependent memory tasks. Neurally, animal studies have revealed that stress alters ensuing synaptic plasticity and firing properties of hippocampal…

Epigenetic modifications of chromatin structure provide a mechanistic interface for gene-environment interactions that impact the individualization of health trajectories across the lifespan. A growing body of research indicates that dysfunctional epigenetic regulation contributes to poor cognitive outcomes among aged populations. Here we review…

Damage to structures in the human medial temporal lobe causes severe memory impairment. Animal object recognition tests gained prominence from attempts to model "global" human medial temporal lobe amnesia, such as that observed in patient HM. These tasks, such as delayed nonmatching-to-sample and spontaneous object recognition, for assessing…

Data suggesting that different brain circuits may underlie different forms of learning and memory are reviewed. Several current theories of learning and memory with respect to hippocampal and other brain circuit involvement are considered. (PCB)

The relationship between current information processing and prior associative theories of human and animal learning, memory, and amnesia are discussed. The paper focuses on the two components of the amnesic syndrome, retrograde amnesia and anterograde amnesia. A neural theory of chunking and consolidation is proposed. (Author/RD)

Examines how the contributions of animal research are presented in eight of the most widely used introductory psychology textbooks. The authors show that, with the exception of principles of conditioning and learning, the contributions of animal research are often not explicitly acknowledged or are obscured to look like they had been obtained with…

Synaptic plasticity is thought to contribute to memory formation. Serotonin-induced facilitation of sensory-motor (SN-MN) synapses in "Aplysia" is an extensively studied cellular analog of memory for sensitization. Serotonin, a modulatory neurotransmitter, is released in the CNS during sensitization training, and induces three temporally and…
