We investigated action potentials recorded from the adult rat hippocampus and neocortex before, during and after novel object exploration (experimental periods)."
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 such as amplitude laminar profile, resistance to cholinergic blockers, and differential entrainment of gamma oscillations. This signal is postulated to link olfactory and hippocampal networks for the processing of sensory information."
Undersampled Critical Branching Processes on Small-World and Random Networks Fail to Reproduce the Statistics of Spike Avalanches"
Apr 23, 2014
We conclude that undersampled branching-process-like models in these topologies fail to reproduce the statistics of spike avalanches."
Increased hippocampal excitability and impaired spatial memory function in mice lacking VGLUT2 selectively in neurons defined by tyrosine hydroxylase promoter activity"
Apr 11, 2014
These knockout mice showed impairment in spatial memory function. Electrophysiological analyses revealed a profound alteration of oscillatory activity in the CA3 region of the hippocampus."
We discuss four specific cases in which neuroscience synergizes with other disciplines to serve education, ranging from very general physiological aspects of human learning such as nutrition, exercise and sleep, to brain architectures that shape the way we acquire language and reading, and neuroscience tools that increasingly allow the early detection of cognitive deficits, especially in preverbal infants."
Graph analysis of verbal fluency test discriminate between patients with Alzheimer’s disease, Mild Cognitive Impairment and normal elderly controls"
Jul 11, 2014
This study reports a graph analysis of data generated by the semantic verbal fluency test by cognitively healthy elderly (NC), patients with Mild Cognitive Impairment – subtypes amnestic (aMCI) and amnestic multiple domain (a+mdMCI) - and patients with Alzheimer’s disease (AD)."
We found that the phase and amplitude of multiple LFP frequencies carry information about stimuli, which have specific time courses after stimulus delivery."
Limiting glutamate transmission in a Vglut2-expressing subpopulation of the subthalamic nucleus is sufficient to cause hyperlocomotion"
Jun 18, 2014
Our results demonstrate that altering the contribuition of a limited population within the STN is sufficiente to achieve results similar to STN lesions and high-frequecy stimulation, but with fewer side effects."

Naps in school can enhance the duration of declarative memories learned by adolescents"
Jun 03, 2014
Here we set out to evaluate the influence of daytime naps on the duration of declarative memories learned in school by students of 10–15 years old."
