• Measurement of cognitive bias and cortisol levels to evaluate the effects of space restriction on captive collared peccary (Mammalia, Tayassuidae)

  • Human Brain Expansion during Evolution Is Independent of Fire Control and Cooking

    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...
  • Impacts of social support on symptoms in Brazilian women with fibromyalgia

  • Repertoires of Spike Avalanches Are Modulated by Behavior and Novelty

    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...
  • Motor Coordination Correlates with Academic Achievement and Cognitive Function in Children

    The relationship between exercise and cognition is an important topic of research that only recently began to unravel.
  • Live Imaging of Adult Neural Stem Cells in Rodents

    Adult Neural Stem Cells (NSC) in the mouse subventricular zone (SVZ) tracked by retroviral labeling during embryonic development (GFP, green) and identified by the proliferative (Ki67, blue) and astrocyte-specific marker (GFAP, red).
  • Psychosis and the Control of Lucid Dreaming

    Dreaming and psychosis share important features, such as intrinsic sense perceptions independent of external stimulation, and a general lack of criticism that is associated with reduced frontal cerebral activity.
  • Variation of glucocorticoid metabolite levels is associated with survival demands in immature and reproductive demands in adult wild black capuchins (Sapajus nigritus)

  • Impaired theta-gamma coupling in APP-deficient mice

    The amyloid precursor protein (APP) is critically involved in the pathophysiology of Alzheimer’s disease, but its physiological functions remain elusive. This work shows that lack of APP reduces oscillatory coupling in voltage recordings from specific brain regions, despite not affecting the amplitude...
  • Do lateral intrinsic and callosal axons have comparable actions in early visual areas ?

    By comparing data from lateral and feedback circuits, we conclude that visual callosal connections are more similar to intrinsic connections and can be interpreted as extending this circuit across the hemispheres.
  • Physiological and behavioral responses to routine procedures in captive common marmosets (Callithrix jacchus)

  • Hippocampal Respiration-Driven Rhythm Distinct from Theta Oscillations in Awake Mice

    This work demonstrates that the hippocampus of awake mice produces slow oscillations that are entrained by nasal respiration. The rhythm is close in frequency to, but distinct from, classical theta oscillations. The results suggest that respiration-coupled oscillations aid the exchange of information...
