  • Detecting cell assemblies in large neuronal populations

    Here we review three linear methods for the detection of cellassemblies in large neuronal populations that rely on principal and independent component analysis.
  • Ketamine alters oscillatory coupling in the hippocampus

    Network interactions that underlie cognitively relevant oscillatory coupling in the hippocampus are altered upon NMDA receptor blockade by ketamine, a pharmacological model of schizophrenia.
  • Os Portões Iluminados da Memória

    Novos marcadores celulares associados a ferramentas optogenéticas têm permitido que pesquisadores compreendam as funções de tipos específicos de neurônios, e, com isso, revelam possíveis mecanismos de processamento de informação no cérebro.
  • Global slowing of network oscillations in mouse neocortex by diazepam.

    We therefore analyzed diazepam effects on a large range of cortical network oscillations in freely moving mice, including theta (4e12 Hz), gamma (40e100 Hz) and fast gamma (120e160 Hz) oscillations. We also investigated diazepam effects over the coupling between theta phase and...
  • On High-Frequency Field Oscillations (>100 Hz) and the Spectral Leakage of Spiking Activity.

    Our results argue against the idea that all high-frequency LFP activity stems from spike contamination and suggest avoiding defining brain rhythms solely based on frequency range.
  • Theta-associated high-frequency oscillations (110-160 Hz) in the hippocampus and neocortex.

    We review recent evidence for a novel type of fast cortical oscillatory activity that occurs circumscribed between 110 and 160 Hz, which we refer to as high-frequency oscillations (HFOs).
