Numerical Processing: Stimulating Numbers

A new study using transcranial direct current stimulation shows that modulating parietal cortex activity during the learning of abstract numerical material can enhance numerical competency for up to six months.

Semantic processing of neglected numbers.

While neglected stimuli can still be processed, few studies have directly addressed the issue of the unconscious access to semantics. In order to clarify this issue, we engaged four patients with unilateral left spatial neglect in a number comparison task. Each target number was preceded by a lateralized number prime, either in the intact or neglected hemifield (HF). Both group analyses and the...

Numerical Semigroups, Cyclotomic Polynomials, and Bernoulli Numbers

We give two proofs of a folkore result relating numerical semigroups of embedding dimension two and binary cyclotomic polynomials and explore some consequences. In particular, we give a more conceptual reproof of a result of Hong et al. (2012) on gaps between the exponents of non-zero monomials in a binary cyclotomic polynomial. The intent of the author with this paper is to popularise cyclotom...

Numerical Cognition: Reading Numbers from the Brain

How the human brain encodes numbers is revealed by a new analysis of patterns of brain activity. The findings address the nature of numerical representations and homology between humans and non-human primates.
