"A Respiration-Coupled Rhythm in the Rat Hippocampus Independent of Theta and Slow Oscillations"

Hippocampal respiration rhythm in rats. This work shows that the hippocampus produces two low-frequency rhythms at nearby frequencies: one that couples to respiration and another that is coupled to the neocortex. The results support a role for brain oscillations in connecting distant brain regions, and posit the respiratory cycle as an important reference for neuronal communication between olfactory and memory networks.

A Respiration-Coupled Rhythm in the Rat Hippocampus Independent of Theta and Slow Oscillations"

Hippocampal respiration rhythm in rats. This work shows that the hippocampus produces two low-frequency rhythms at nearby frequencies: one that couples to respiration and another that is coupled to the neocortex. The results support a role for brain oscillations in connecting distant brain regions, and posit the respiratory cycle as an important reference for neuronal communication between olfactory and memory networks."

A genetic network that suppresses genome rearrangements in Saccharomyces cerevisiae and contains defects in cancers"
May 06, 2016

Gross chromosomal rearrangements (GCRs) play an important role in human diseases, including cancer. The identity of all Genome Instability Suppressing (GIS) genes is not currently known."

Human Brain Expansion during Evolution Is Independent of Fire Control and Cooking"
Apr 25, 2016

What makes humans unique? This question has fascinated scientists and philosophers for centuries and it is still a matter of intense debate. Nowadays, human brain expansion during evolution has been acknowledged to explain our empowered cognitive capabilities. The drivers for such accelerated expansion remain, however, largely unknown. In this sense, studies have suggested that the cooking of food could be a pre-requisite for the expansion of brain size in early hominins. "

Repertoires of Spike Avalanches Are Modulated by Behavior and Novelty"
Mar 28, 2016

Esse artigo mostra em ratos que avalanches neuronais variam através do ciclo sono vigília e refletem em alguma medida os comportamentos dos animais. Detectamos a existência de repertórios complexos de padrões de ativação entre neurônios (avalanches) que são construídas na vigília e reverberadas/repetidas durante o sono. As repetições podem acontecer com intervalos de muitos minutos, se estendendo por várias horas."

Motor Coordination Correlates with Academic Achievement and Cognitive Function in Children"
Mar 15, 2016

The relationship between exercise and cognition is an important topic of research that only recently began to unravel."

A Naturalistic Assessment of the Organization of Children’s Memories Predicts Cognitive Functioning and Reading Ability"
Aug 05, 2016

To explore the relationship between memory and early school performance, we used graph theory to investigate memory reports from 76 children aged 6–8 years. The reports comprised autobiographical memories of events days to years past, and memories of novel images reported immediately after encoding."

Novel Virtual Environment for Alternative Treatment of Children with Cerebral Palsy"
Jul 12, 2016

In this paper, we describe a virtual environment for patients to engage in a playful therapeutic game for neuropsychomotor rehabilitation, based on the experience of the occupational therapy program of the Nucleus for Integrated Medical Assistance (NAMI) at the University of Fortaleza, Brazil. "

Pre-ictal increase in theta synchrony between the hippocampus and prefrontal cortex in a rat model of temporal lobe epilepsy"
Jun 28, 2016

We used a TLE rat model generated by perforant path (PP) stimulation to understand whether synchrony between dorsal hippocampal and mPFC networks is altered shortly before a seizure episode."

Computational Tracking of Mental Health in Youth: Latin American Contributions to a Low-Cost and Effective Solution for Early Psychiatric Diagnosis"
Jun 16, 2016

Here, we briefly introduce the problem by reviewing the scarce epidemiological data from Latin America regarding the onset of mental disorders, and discussing the difficulties associated with early diagnosis. "

Radiological Characterization of Cerebral Phenotype in Newborn Microcephaly Cases from 2015 Outbreak in Brazil"
Jun 16, 2016

Brazil is facing, since October of 2015, an outbreak of microcephalic fetuses. This outbreak is correlated with the beginning of circulation of Zika virus (ZIKV) in the country."
