Representations Of Space

AbstractNeural circuits generate representations of the external world from multiple information streams. The navigation system provides an exceptional lens through which we may gain insights about how such computations are implemented. Neural circuits in the medial temporal lobe construct a map-like representation of space that supports navigation. This computation integrates multiple sensory cues, and, in addition, is thought to require cues related to the individual’s movement through the environment. Here, we identify multiple self-motion signals, related to the position and velocity of the head and eyes, encoded by neurons in a key node of the navigation circuitry of mice, the medial entorhinal cortex (MEC). The representation of these signals is highly integrated with other cues in individual neurons. Such information could be used to compute the allocentric location of landmarks from visual cues and to generate internal representations of space.

Directional Variation

Given that geographers excel at measuring and explaining spatial variations in attributes, it is surprising that they are not more aware that relationships may vary over space. It is still normal practice, for example, to estimate a set of parameters in a model and to assume that the relationships represented by these values apply equally to all locations and in all directions. Recently, however, there have been several applications of Casetti's expansion method that have been focused on measuring anisotropic trends around locations. Here this technique is used to examine possible anisotropy in distance-decay relationships around origins. That is, the authors attempt to answer the question: does the rate of distance decay vary with direction? The conclusions reached in previous research on this topic are only partially supported here. Via US migration data, it is suggested that although there is evidence of directional variation in distance decay around some origins, and this evidence leads to some interesting insights into the mental representation of space by US migrants, it is impossible to identify any overall trend across origins in directional variability.

Representation Of Space

O'Keefe (1991) has proposed that spatial information in rats might be represented as phasors: phase and amplitude of a sine wave encoding angle and distance to a landmark. We describe computer simulations showing that operations on phasors can be efficiently realized by arrays of spiking neurons that recode the temporal dimension of the sine wave spatially. Some cells in motor and parietal cortex exhibit response properties compatible with this proposal.

Present Trial

Humans effortlessly establish a gist-like memory of their environment whenever they enter a new place, a memory that can guide action even in the absence of vision. Neurons in the lateral intraparietal area (LIP) of the monkey exhibit a form of this environmental memory. These neurons respond when a monkey makes a saccade that brings the spatial location of a stimulus that appeared on a number of prior trials, but not on the present trial, into their receptive fields (RFs). The stimulus need never have appeared in the neuron’s RF. This memory response is usually weaker, with a longer latency than the neuron’s visual response. We suggest that these results demonstrate that LIP has access to a supraretinal memory of space, which is activated when the spatial location of the vanished stimulus can be described by a retinotopic vector from the center of gaze to the remembered spatial location.

Claude-Henri Grignon’s novel Un homme et son péché presents the life of French Canadian colonial settlers of the Laurentides region at the end of XIXth century. It depicts a realistic image of the colonisation period of Quebec history. The novel is at the origin of a media series that englobes a radio adaptation, three filmic adaptations, theater adaptations, a comic, and two television series. The aim of this article is to discuss the vision of colonisation by analysing two television series based on Un homme et son péché: Les Belles Histoires des pays d’en haut broadcast from 1956 to 1970 and Les Pays d’en haut broadcast from 2016 to 2019 on ICI Radio-Canada Télé 1. The analysis will try to trace modifications inherent to the process of adaptation on different levels (protagonists, representation of space, ideological discourse) and their influence on the vision of the colonisation period.

Spatial Continuum

The question of ways of creating a spatial continuum in the early stories of I. A. Bunin “On the wrong side”, “On the farm” and “On the Donets”, united by a single principle of nomination and included in the first book of the writer’s prose “To the end of the world” (1897) is considered in the article. The semantics of the title actualizes the spatial component of the author’s linguistic picture of the world, which determined the path of linguistic and stylistic analysis of the linguistic material of stories. The authors pay special attention to the means of lexical representation of space as one of the basic linguo-cognitive categories. The novelty of the research lies in the fact that the language material has been identified, systematized and described, which makes it possible to determine the individual author's characteristics in the creation of the spatial continuum of I. A. Bunin’s early stories. The relevance of the study is due to the appeal to the problems of cognitive linguistics. On the basis of statistical, descriptive and linguo-cognitive methods of analysis, the authors identify and describe the means of lexical representation of the spatial model created in the stories of I. A. Bunin, which is characterized by a clear structuredness and individuality of the author’s approach. In the course of the study, the authors come to conclusions that make it possible to characterize the features of the construction of space in the early stories of the writer, taking into account the individual characteristics of the author's world modeling, and also to analyze the linguistic parameters of the idiostyle of I. A. Bunin.
