Adult Neural Stem Cells (NSC) in the mouse subventricular zone (SVZ) tracked by retroviral labeling during embryonic development (GFP, green) and identified by the proliferative (Ki67, blue) and astrocyte-specific marker (GFAP, red)."
Impaired theta-gamma coupling in APP-deficient mice"
Feb 26, 2016
The amyloid precursor protein (APP) is critically involved in the pathophysiology of Alzheimer’s disease, but its physiological functions remain elusive. This work shows that lack of APP reduces oscillatory coupling in voltage recordings from specific brain regions, despite not affecting the amplitude of the oscillations, thus pointing to reduced cross-frequency coupling as a functional marker of APP deficiency at the network level."
This work demonstrates that the hippocampus of awake mice produces slow oscillations that are entrained by nasal respiration. The rhythm is close in frequency to, but distinct from, classical theta oscillations. The results suggest that respiration-coupled oscillations aid the exchange of information between olfactory and memory networks. "

A genetic network that suppresses genome rearrangements in Saccharomyces cerevisiae and contains defects in cancers"
May 28, 2016
Gross chromosomal rearrangements (GCRs) play an important role in human diseases, including cancer. The identity of all Genome Instability Suppressing (GIS) genes is not currently known."
What makes humans unique? This question has fascinated scientists and philosophers for centuries and it is still a matter of intense debate. Nowadays, human brain expansion during evolution has been acknowledged to explain our empowered cognitive capabilities. The drivers for such accelerated expansion remain, however, largely unknown. In this sense, studies have suggested that the cooking of food could be a pre-requisite for the expansion of brain size in early hominins. "
Esse artigo mostra em ratos que avalanches neuronais variam através do ciclo sono vigília e refletem em alguma medida os comportamentos dos animais. Detectamos a existência de repertórios complexos de padrões de ativação entre neurônios (avalanches) que são construídas na vigília e reverberadas/repetidas durante o sono. As repetições podem acontecer com intervalos de muitos minutos, se estendendo por várias horas."

Psychosis and the Control of Lucid Dreaming"
Mar 09, 2016
Dreaming and psychosis share important features, such as intrinsic sense perceptions independent of external stimulation, and a general lack of criticism that is associated with reduced frontal cerebral activity."
