Experience-dependent upregulation of multiple plasticity factors in the hippocampus during early REM sleep"
Mar 17, 2015
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"

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."
Dopamine and sleep have been independently linked with hippocampus-dependent learning."
Input and Output Gain Modulation by the Lateral Interhemispheric Network in Early Visual Cortex"
May 27, 2015
Neurons in the cerebral cortex are constantly integrating different types of inputs. Dependent on their origin, these inputs can be modulatory in many ways and, for example, change the neuron's responsiveness, sensitivity, or selectivity. "
Interplay of environmental signals and progenitor diversity on fate specification of cortical GABAergic neurons"
May 13, 2015
Cortical GABAergic interneurons constitute an extremely diverse population of cells organized in a well-defined topology of precisely interconnected cells."
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. "
The Changing Brain Symposium is a Satellite event to IBRO 2015. Organized by Dr. Marcos R. Costa (Brain Institute, Natal) and Dr. Cecilia Hedin Pereira (Oswaldo Cruz Foundation, Rio de Janeiro), the symposium will discuss new advances in the study of brain development and adult neurogenesis."
