Estimating the distance to a hereditary graph property

Carlos Hoppen, Yoshiharu Kohayakawa, Richard Lang, Hanno Lefmann and Henrique Stagni

Given a family of graphs "F", we prove that the distance to being induced "F"-free is estimable with a query complexity that depends only on the bounds of the Frieze-Kannan Regularity Lemma and a Removal Lemma for "F".

Dopamine Modulates Delta-Gamma Phase-Amplitude Coupling in the Prefrontal Cortex of Behaving Rats

Dopamine release and phase-amplitude cross-frequency coupling (CFC) have independently been implicated in prefrontal cortex (PFC) functioning. To causally investigate whether dopamine release affects phase-amplitude comodulation between different frequencies in local field potentials (LFP) recorded from the medial PFC (mPFC) of behaving rats, we used RuBiDopa, a light-sensitive caged compound that releases the neurotransmitter dopamine when irradiated with visible light. LFP power did not change in any frequency band after the application of light-uncaged dopamine, but significantly strengthened phase-amplitude comodulation between delta and gamma oscillations. Saline did not exert significant changes, while injections of dopamine and RuBiDopa produced a slow increase in comodulation for several minutes after the injection. The results show that dopamine release in the medial PFC shifts phase-amplitude comodulation from theta-gamma to delta-gamma. Although being preliminary results due to the limitation of the low number of animals present in this study, our findings suggest that dopamine-mediated modification of the frequencies involved in comodulation could be a mechanism by which this neurotransmitter regulates functioning in mPFC.

"The Arms of Nildo and Rony:" a NeuroMat story

A professional motorcyclist and a surgeon meet up at the waiting room of a physiotherapy clinic. They share a common story: rehabilitation after a traumatic brachial plexus injury. Their fate is somehow similar to the one of a famous soccer player who, after a serious lesion, must attend therapy sections to learn again how to play, after a period of recovery. These stories are the guiding narratives of a newly released educational material for patients, caregivers and health professionals, the illustrated magazine "The Arms of Nildo and Rony."
