Increased hippocampal excitability and impaired spatial memory function in mice lacking VGLUT2 selectively in neurons defined by tyrosine hydroxylase promoter activity

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.

Neuroscience and education: prime time to build the bridge

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.

Increase in Hippocampal Theta Oscillations during Spatial Decision Making.

In this study, we investigated to what extent spatial decision making modulates hippocampal theta oscillations when controlling for variations in locomotion speed.

Sonic hedgehog signaling regulates mode of cell division of early cerebral cortex progenitors and increases.

In this work, we investigated whether SHH signaling influences the behavior of neural progenitors isolated from the dorsal telencephalon, which generate excitatory neurons and macroglial cells in vitro. We observed that SHH increases proliferation of cortical progenitors and generation of astrocytes, whereas blocking SHH signaling with cyclopamine has opposite effects.

Sleep and school education

Here we review the biological and psychological phenomena underlying the cognitive role of sleep, present the few published studies on sleep and learning that have been performed in schools, and discuss potential applications of sleep to the school setting. Translational research on sleep and learning has never seemed more appropriate.

Overweight People Have Low Levels of Implicit Weight Bias, but Overweight Nations Have High Levels of Implicit Weight Bias

We investigated whether the national and cultural context – particularly the national prevalence of obesity – predicts attitudes toward overweight people independent of personal identity and weight status.

Graph analysis of dream reports is especially informative about psychosis

Dream reports are substantially more informative about the mental state of psychotic subjects than waking reports.

Novo, mas nem tão admirável

Neurocientista traça a história do uso de substâncias que estimulam o ser humano a sonhar acordado e examina como a cultura psicodélica influenciou o cinema e a literatura, de Aldous Huxley a William Gibson, criadores que vislumbraram caminhos alternativos para uma civilização centrada no acúmulo.

Bases biológicas da atividade onírica

Para entender os sonhos, é preciso primeiro considerar que nos faltam as evidências diretas que emprestam plausibilidade evolutiva a tantas narrativas sobre o surgimento de estruturas ou processos biológicos.

Neurobiology and clinical implications of lucid dreaming

Several lines of evidence converge to the idea that rapid eye movement sleep (REMS) is a good model to foster our understanding of psychosis.

Dream characteristics in a Brazilian sample: an online survey focusing on lucid dreaming.

During sleep, humans experience the offline images and sensations that we call dreams, which are typically emotional and lacking in rational judgment of their bizarreness.

An Updated Midline Rule: Visual Callosal Connections Anticipate Shape and Motion in Ongoing Activity across the Hemispheres

If trajectory and direction of motion are known beforehand, the detection of a moving object at future positions might be facilitated. In agreement, primary visual cortical neurons close to the visual field's midline seem to anticipate movements and shapes of objects which could potentially cross from one visual hemifield into the other.
