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."
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."

How did human consciousness arise, in comparison with that of apes?"
Proliferative Defects and Formation of a Double Cortex in Mice Lacking Mltt4 and Cdh2 in the Dorsal Telencephalon"
Aug 06, 2014
Here we show that the adherens junction proteins afadin and CDH2 are critical for the control of cell proliferation in the dorsal telencephalon and for the formation of its normal laminar structure."
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."

O feito é de Nathalia Lemos, Janaina Weissheimer e Sidarta Ribeiro, da Universidade Federal do Rio Grande do Norte. Eles publicaram em junho artigo no periódico "Frontiers of Systems Neuroscience" mostrando que meninos e meninas de 10 a 15 anos retinham melhor novos conhecimentos, após cinco dias, caso tivessem tirado uma soneca logo depois de aprendê-los.
