Theta oscillations provide temporal windows for local circuit computation in the entorhinal-hippocampal loop.

27 Oct 2009 Theta oscillations are believed to play an important role in the coordination of neuronal firing in the entorhinal (EC)-hippocampal system but the underlying mechanisms are not known. We simultaneously recorded from neurons in multiple regions of ... Read more...

Alteration of theta timescale dynamics of hippocampal place cells by a cannabinoid is associated with memory impairment.

5 Oct 2009 The integrity of the hippocampus is critical for both spatial navigation and episodic memory, but how its neuronal firing patterns underlie those functions is not well understood. In particular, the modality by which hippocampal place cells ... Read more...

Transcallosal connectivity and cortical rhythms: findings in children with spina bifida.

24 Aug 2009 We studied the relation between cortical oscillatory rhythms and the structural integrity of the corpus callosum in 21 children with spina bifida and hydrocephalus. Participants underwent resting state neuromagnetic recordings and diffusion tensor ... Read more...
