How does the human brain store sequences of spatial locations? The standard view is that each consecutive item occupies a distinct slot in working memory. Here, we formulate and test the alternative hypothesis that the human brain compresses the whole sequence using an abstract, language-like code that captures the numerical and geometrical regularities of the sequence at multiple nested levels. We exposed participants to spatial sequences of fixed length but variable regularity, and asked them… Expand

A Theory of Consciousness from a Theoretical Computer Science Perspective: Insights from the Conscious Turing Machine
This work formalizes a modified version of the Global Workspace Theory of consciousness originated by cognitive neuroscientist Bernard Baars and further developed by him, Stanislas Dehaene, Jean-Pierre Changeaux and others to provide a simple computational model of consciousness. Expand


Representation of spatial sequences using nested rules in human prefrontal cortex
It is proposed that humans are endowed with a simple “language of geometry” which recruits a dorsal prefrontal circuit for geometrical rules, distinct from but close to areas involved in natural language processing. Expand
The language of geometry: Fast comprehension of geometrical primitives and rules in human adults and preschoolers
A novel paradigm in which subjects are exposed to a sequence of spatial locations on an octagon, and are asked to predict future locations is introduced, and it is concluded that subjects encode visuospatial sequences by minimizing the complexity of the structured expressions that capture them.

Memory for serial order across domains: An overview of the literature and directions for future research.
It is proposed that functional similarities across domains buttress the notion that verbal, visual, and spatial sequences are planned and controlled by a competitive queuing (CQ) mechanism in which items are simultaneously active in parallel and the strongest item is chosen for output. Expand
The cortical representation of simple mathematical expressions
It is suggested that mathematical syntax, although arising historically from language competence, becomes "compiled" into visuo-spatial areas in well-trained mathematics students. Expand
From Numerosity to Ordinal Rank: A Gain-Field Model of Serial Order Representation in Cortical Working Memory
A new model of how serial order is represented in working memory is advanced, predicated on three key findings from neurophysiological research: prefrontal neurons that code conjunctively for item and order, parietal neurons that represent count information through a graded and compressive code, and multiplicative gain modulation as a mechanism for information integration.

Representation of Numerical and Sequential Patterns in Macaque and Human Brains
Using fMRI in untrained macaques and humans, a recently evolved circuit may endow humans with a unique ability for representing linguistic and non-linguistic sequences in a unified manner. Expand
Mapping of a non-spatial dimension by the hippocampal/entorhinal circuit
Neurons involved in this representation overlapped with the known spatial cell types in the circuit, such as place cells and grid cells, suggesting that common circuit mechanisms in the hippocampal–entorhinal system are used to represent diverse behavioural tasks, possibly supporting cognitive processes beyond spatial navigation.

Production of Supra-regular Spatial Sequences by Macaque Monkeys
Using a production task, it is shown that macaque monkeys can be trained to produce time-symmetrical embedded spatial sequences whose formal description requires supra-regular grammars or, equivalently, a push-down stack automaton. Expand

A major separation between two brain networks for mathematical and non-mathematical semantics is indicated, which goes a long way to explain a variety of facts in neuroimaging, neuropsychology and developmental disorders. Expand
Eye Movement-Related Confounds in Neural Decoding of Visual Working Memory Representations
A potential remedy is demonstrated, whereby the decoders are trained on a functional localizer that was specifically designed to target bottom-up sensory signals and as such avoids eye movements, and argued for more awareness of the potentially pervasive and ubiquitous effects of eye movement-related confounds.
