Extinction procedure induces pruning of dendritic spines in CA1 hippocampal field depending on strength of training in rats by María Eugenia Garín-Aguilar, Sofía eDíaz-Cintra, Andrea C. Medina, Gina Lorena Quirarte, Azucena eAguilar-Vázquez, Roberto A Prado-Alcalá

“…These results indicate that pruning is involved in behavioral extinction, while maintenance of spines is a probable mechanism that mediates the protecting effect against amnesic treatments produced by enhanced training.…”

Non-linear susceptibility to interferences in declarative memory formation. by Malen D Moyano, Giulia Carbonari, Matías Bonilla, María E Pedreira, Luis I Brusco, Laura Kaczer, Cecilia Forcato

“…On day 1, participants learned a list of non- syllable pairs (List 1). 5 min, 30 min, 3 h or 8 h later, they received an interference list (List 2) that acted as an amnesic agent. On day 2 (48 h after training) participants had to recall List 1 first, followed by List 2. …”

The role of the perirhinal cortex and hippocampus in learning, memory, and perception. by Buckley, M

“…Indeed, human patients with extensive MTL damage are typically profoundly amnesic whereas patients with less extensive brain lesions centred upon the hippocampus typically exhibit only moderately severe anterograde amnesia. …”

Scene-specific memory for objects: a model of episodic memory impairment in monkeys with fornix transection. by Gaffan, D

“…The impairments of object memory in the present experiments are analogous to the impairments of episodic memory seen in human amnesic patients. …”

Human medial temporal lobe damage can disrupt the perception of single objects. by Lee, A, Rudebeck, SR

“…To address these issues, this study investigated object perception in two human amnesic patients who were chosen on the basis of their lesion locations and suitability for detailed neuroimaging investigation. …”

Medial temporal lobe activity during complex discrimination of faces, objects, and scenes: Effects of viewpoint. by Barense, MD, Henson, R, Lee, A, Graham, K

“…Recent studies, however, demonstrated perceptual impairments in amnesic individuals with MTL damage, with hippocampal lesions causing scene discrimination deficits, and perirhinal lesions causing object and face discrimination deficits. …”

Lesion of the hippocampus selectively enhances LEC’s activity during recognition memory based on familiarity by Liv Mahnke, Erika Atucha, Eneko Pina-Fernàndez, Takashi Kitsukawa, Magdalena M. Sauvage

“…These findings suggest that different mechanisms support familiarity in LEC and PER and led to the hypothesis that HIP might exert a tonic inhibition on LEC during recognition memory that is released when HIP is compromised, possibly constituting a compensatory mechanism in aging and amnesic patients.…”

General anesthetic agents induce neurotoxicity through astrocytes by Yanchang Yang, Tiantian Liu, Jun Li, Dandan Yan, Yuhan Hu, Pin Wu, Fuquan Fang, Patrick M McQuillan, Wenxin Hang, Jianhang Leng, Zhiyong Hu

“…Astrocytes can also be an important target of general anesthetic agents as they exert not only sedative, analgesic, and amnesic effects but also mediate general anesthetic-induced neurotoxicity and postoperative cognitive dysfunction. …”

Infusing zeta inhibitory peptide into the perirhinal cortex of rats abolishes long-term object recognition memory without affecting novel object location recognition by Keanan Augereau, Paola V. Migues, Oliver Hardt

“…Infusing the amnesic agent zeta inhibitory peptide (ZIP) into the dorsal hippocampus disrupts established long-term object location recognition memory without affecting object identity recognition, which likely depends on the perirhinal cortex. …”

GHB acid: A rage or reprive by Prakhar Kapoor, Revati Deshmukh, Ipsita Kukreja

“…GHB is abused by three main groups of users: Body builders who use the substance believing that it stimulated the release of growth hormone; sexual predators who covertly administer the drug for its sedative and amnesic effects and club-goers (rave parties) who take the drug for its euphoric effects. …”

Landmark recognition in Alzheimer's dementia: spared implicit memory for objects relevant for navigation. by Roy P C Kessels, Amy van Doormaal, Gabriele Janzen

“…Since there is evidence that implicit learning is intact in amnesic patients, the current study examined memory for objects relevant for navigation in patients with Alzheimer's dementia (AD). …”

Enhancing cortical network-level participation coefficient as a potential mechanism for transfer in cognitive training in aMCI by Quanjing Chen, Adam Turnbull, Martin Cole, Zhengwu Zhang, Feng V. Lin

“…Effective cognitive training must improve cognition beyond the trained domain (show a transfer effect) and be applicable to dementia-risk populations, e.g., amnesic mild cognitive impairment (aMCI). Theories suggest training should target processes that 1) show robust engagement, 2) are domain-general, and 3) reflect long-lasting changes in brain organization. …”

Time to go our separate ways: Opposite effects of study duration on priming and recognition reveal distinct neural substrates by Joel eVoss, Brian eGonsalves

“…Amnesic patients have difficulties recognizing when stimuli are repeated, even though their responses to stimuli can change as a function of repetition in indirect tests of memory—a pattern known as priming without recognition. …”

Overtraining Strengthens the Visual Discrimination Memory Trace Outside the Hippocampus in Male Rats by Hugo Lehmann, Morgan G. Stykel, Melissa J. Glenn

“…In Experiment 3, increasing the additional learning beyond criterion by 230 trials, the amount needed in Experiment 2 to train the non-hippocampal systems in absence of competition, successfully prevented the retrograde amnesic effects of post-training hippocampal damage. …”
