  • Sleep Paralysis in Brazilian Folklore and Other Cultures: A Brief Review

    10/24/2016
    Sleep paralysis (SP) is a dissociative state that occurs mainly during awakening.
  • Music Proficiency and Quantification of Absolute Pitch: A Large-Scale Study among Brazilian Musicians

    10/14/2016
    Absolute pitch (AP) is the ability to identify and name the pitch of a sound without external reference.
  • Machine Learning Algorithms for Automatic Classification of Marmoset Vocalizations

    09/29/2016
    In this work, we consider seven different classification algorithms with the goal of finding a robust classifier that can be successfully trained on small datasets.
  • Rats Synchronize Locomotion with Ultrasonic Vocalizations at the Subsecond Time Scale

    09/29/2016
    Acoustic signals have the potential for transmitting information fast across distances. Rats emit ultrasonic vocalizations of two distinct classes: “22-kHz” or “alarm” calls and “50-kHz” calls.
  • A Naturalistic Assessment of the Organization of Children’s Memories Predicts Cognitive Functioning and Reading Ability

    08/05/2016
    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...
  • Novel Virtual Environment for Alternative Treatment of Children with Cerebral Palsy

    07/12/2016
    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,...
  • Decreased neuron loss and memory dysfunction in pilocarpine-treated rats pre-exposed to hypoxia.

    07/06/2016
    Our findings indicated that short hypoxic preconditioning preceding SE promotes long-lasting protective effects on neuron survival and spatial memory.
  • Pre-ictal increase in theta synchrony between the hippocampus and prefrontal cortex in a rat model of temporal lobe epilepsy

    06/28/2016
    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

    06/16/2016
    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

    06/16/2016
    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.
  • A Respiration-Coupled Rhythm in the Rat Hippocampus Independent of Theta and Slow Oscillations

    05/11/2016
    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...
  • A genetic network that suppresses genome rearrangements in Saccharomyces cerevisiae and contains defects in cancers

    05/03/2016
    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.
