AbstractBehavioral tasks must be evaluated in terms of the cognitive functions they require. The tasks described in this unit are useful for detecting stimulation by drugs or a small electrical current, impairment of normal function by production of lesions or administration of a pharmacologic or toxicologic agent, recording activity during performance

Among the different capabilities of animals, the formation of spatial memories is crucial for their life. Living beings able to move, constantly need to orient themselves in the environment to reach a target that might be not always visible. This chapter investigates the process of spatial memory formation as an essential ingredient for orientation in ...

The evolution of spatial memory
Mathematical Biosciences, 2013Models of foraging behaviour often assume either that animals are searching for resources, and therefore have no prior knowledge of resource locations, or that they are effectively omniscient, with a comprehensive knowledge of their habitat. By contrast, few attempts have been made to examine the actual conditions under which spatial memory will ...

Cerebellar contributions to spatial memory
Neuroscience Letters, 2014There is mounting evidence for a role for the cerebellum in working memory (WM). The majority of relevant studies has examined verbal WM and has suggested specialisation of the right cerebellar hemisphere for language processing. Our study used theta burst stimulation (TBS) to examine whether there is a converse cerebellar hemispheric specialisation ...

Spatial movement with distributed memory
Journal of Mathematical Biology, 2021Diffusion has been widely applied to model animal movement that follows Brownian motion. However, animals typically move in non-Brownian ways due to their perceptual judgment. Spatial memory and cognition recently have received much attention in characterizing complicated animal movement behaviours.

Neuroanatomical bases of spatial memory
Brain Research, 1980Although many brain areas have been implicated in spatial memory processes, recent investigations have focused on the hippocampal formation. The present experiment was designed to determine the relative importance of the hippocampal system as compared to the amygdala, the caudate nucleus, or the frontal cortex. Groups of rats were trained to perform on

Spatial resolution in visual memory
Psychonomic Bulletin & Review, 2014Representations in visual short-term memory are considered to contain relatively elaborated information on object structure. Conversely, representations in earlier stages of the visual hierarchy are thought to be dominated by a sensory-based, feed-forward buildup of information.

Sex Differences in Spatial Memory
Neuroscience, 2020Spatial memory is an essential ability for living. Some studies have demonstrated the finding of sex differences in spatial memory. However, the results are diverse, ranging from "significant difference" to "no difference". In this study, we sought to determine the underlying sex differences observed during spatial memory by examining neurofunctional ...

Thalamic role in spatial memory
Behavioural Brain Research, 1986The contribution of structures in the limbic diencephalon to spatial memory function was investigated. Rats with lesions of either the anteroventral thalamus, anteromedial thalamus, dorsomedial thalamus or mammillary bodies were compared in their ability to perform a delayed alternation task. The results indicate the ablation of the thalamic nuclei did

Chimpanzee Spatial Memory Organization
Science, 1973Juvenile chimpanzees, carried around an outdoor field and shown up to 18 randomly placed hidden foods, remembered most of these hiding places and the type of food that was in each. Their search pattern approximated an optimum routing, and they rarely rechecked a place they had already emptied of food.
