  • Beta2 oscillations (23–30 Hz) in the mouse hippocampus during novel object recognition

    09/01/2014
    In the present study we characterised hippocampal beta2 oscillations in mice during an object recognition task. We found prominent bursts of beta2 oscillations in the beginning of novel exploration sessions (four new objects), which could be readily observed by spectral analysis and...
  • Sabores em ondas cerebrais

    12/01/2014
    Cientistas tentam entender como o cérebro processa informações por meio da atividade individual dos neurônios. Pesquisas recentes mostram como o cérebro apreende e decodifica o que chamamos de realidade.
  • Local Field Potentials in the Gustatory Cortex Carry Taste Information

    06/30/2014
    We found that the phase and amplitude of multiple LFP frequencies carry information about stimuli, which have specific time courses after stimulus delivery.
  • Efeitos da administração aguda de quetamina sobre as oscilações eletrofisiológicas da região ca1 hipocampal

    05/07/2014
  • An investigation of Hebbian phase sequences as assembly graphs

    05/07/2014
    We investigated action potentials recorded from the adult rat hippocampus and neocortex before, during and after novel object exploration (experimental periods).
  • Slow Oscillations in the Mouse Hippocampus Entrained by Nasal Respiration. The Journal of Neuroscience

    04/25/2014
    In this study, the authors demonstrate the existence of a previously unrecognized type of neuronal rhythm in the mouse hippocampus that is entrained by respiration. The rhythm is close in frequency to classical theta oscillations but can be distinguished by several features...
  • Sonic hedgehog signaling regulates mode of cell division of early cerebral cortex progenitors and increases astrogliogenesis

    03/13/2014
    In this work, we investigated whether SHH signaling influences the behavior of neural progenitors isolated from the dorsal telencephalon, which generate excitatory neurons and macroglial cells in vitro. We observed that SHH increases proliferation of cortical progenitors and generation of astrocytes, whereas...
  • Increase in Hippocampal Theta Oscillations during Spatial Decision Making.

    03/13/2014
    In this study, we investigated to what extent spatial decision making modulates hippocampal theta oscillations when controlling for variations in locomotion speed.
