Age‐related decline in human cognition is well known, and there are correlative changes in the function of neocortical and hippocampal neurons. Similarly, age‐related decline in learning has been observed in rodents, including deficits in a hippocampal‐dependent learning paradigm, the Morris...
MacKay and James (2001) demonstrated greater‐than‐normal retrograde amnesia (RA) for lexical‐semantic information in amnesic H.M., a deficit that worsened with aging or represented supranormal age‐linked RA (SARA). The present experiments extend these earlier observations to new types of...
Acetylcholine is involved in learning and memory and, particularly, in olfactory tasks, but reports on its specific role in consolidation processes are somewhat controversial. The present experiment sought to determine the effects of blocking muscarinic cholinergic receptors in the ventral...
Insect navigation is guided by heading vectors that are computed by path integration. Mammalian navigation models, on the other hand, are typically based on map‐like place representations provided by hippocampal place cells. Such models compute optimal routes as a continuous series of locations...
Animal studies have shown that bilateral vestibular deafferentation (BVD) causes deficits in spatial memory that may be related to electrophysiological and neurochemical changes in the hippocampus. Recently, human studies have also indicated that human patients can exhibit spatial memory...
Temporal difference learning (TD) is a popular algorithm in machine learning. Two learning signals that are derived from this algorithm, the predictive value and the prediction error, have been shown to explain changes in neural activity and behavior during learning across species. Here, the...
