"Experience-dependent upregulation of multiple plasticity factors in the hippocampus during early REM sleep"

Sleep is beneficial to learning, but the underlying mechanisms remain controversial. The synaptic homeostasis hypothesis (SHY) proposes that the cognitive function of sleep is related to a generalized rescaling of synaptic weights to intermediate levels, due to a passive downregulation of plasticity mechanisms.

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)."

Local Field Potentials in the Gustatory Cortex Carry Taste Information"
Jun 30, 2014

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."

Astrocyte heterogeneity in the brain: from development to disease"
Mar 25, 2015

In this review, we focused on astrocyte heterogeneity in terms of their morphological, protein expression and functional aspects, and debate in a historical perspective the diversity encountered in glial rogenitors and how they may reflect mature astrocyte heterogeneity."

Specification of excitatory neurons in the developing cerebral cortex: progenitor diversity and environmental influences"
Mar 25, 2015

The mature cerebral cortex harbors a heterogeneous population of glutamatergic neurons, organized into a highly intricate histological architecture. Classically, this mixed population of neurons was thought to be generated sequentially from a seemingly homogenous group of progenitors under the influence of external cues. "

Sleep is beneficial to learning, but the underlying mechanisms remain controversial. The synaptic homeostasis hypothesis (SHY) proposes that the cognitive function of sleep is related to a generalized rescaling of synaptic weights to intermediate levels, due to a passive downregulation of plasticity mechanisms."

The onset of data-driven mental archeology"
Aug 13, 2014

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."
