Morris, Christina H.; Kropp, Jerri J.; Sartain, Christina L. – Forum on Public Policy Online, 2019
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…

Kim, Eun Joo; Pellman, Blake; Kim, Jeansok J. – Learning & Memory, 2015
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…

Spiegel, Amy M.; Sewal, Angila S.; Rapp, Peter R. – Learning & Memory, 2014
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…

Winters, Boyer D.; Saksida, Lisa M.; Bussey, Timothy J. – Neuropsychologia, 2010
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…

Sharma, Shiv K.; Carew, Thomas J. – Learning & Memory, 2004
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…

Klann, Eric; Antion, Marcia D.; Banko, Jessica L.; Hou, Lingfei – Learning & Memory, 2004
It is widely accepted that protein synthesis, including local protein synthesis at synapses, is required for several forms of synaptic plasticity. Local protein synthesis enables synapses to control synaptic strength independent of the cell body via rapid protein production from pre-existing mRNA. Therefore, regulation of translation initiation is…
