"Respiration-Entrained Brain Rhythms Are Global but Often Overlooked"

We summarize recent evidence showing that nasal respiration entrains oscillations at the same frequency as breathing in several regions of the rodent brain.

Embryonic stem cell diferentiation in specifc cell lineages is a major issue in cell biology, and particularly, in regenerative medicine. Neural stem cells (NSCs) have the potential for self-renewal and diferentiation into neurons, astrocytes and oligodendrocytes."

4.10 – Multiple Stages of Memory Formation and Persistence"

Callosal Influence on Visual Receptive Fields Has an Ocular, an Orientation-and Direction Bias"
17/abr/2018

One leading hypothesis on the nature of visual callosal connections (CC) is that they replicate features of intrahemispheric lateral connections. However, CC act also in the central part of the binocular visual field. "

Motion contrast in primary visual cortex: a direct comparison of single neuron and population encoding"
15/fev/2018

We analyzed firing rates and phase-locking to low-gamma frequency in single cells and neuronal assemblies. Motion contrast was reflected in all measures but in semi-independent populations."

Extracting information from the shape and spatial distribution of evoked potentials."

Over 90 years after its first recording, scalp electroencephalography (EEG) remains one ofthe most widely used techniques in human neuroscience research, in particular for the study of event-related potentials (ERPs)."

Subtle Alterations in Spatial Memory Induced by Amyloid Peptides Infusion in Rats"
30/jan/2018

In the present study, we evaluated the effects of a low-dose 15-day long treatment with Ab peptides on spatial and non-spatial strategies of rats tested in the Barnes maze. Ab peptides (0.5 mL/site/day; 30 pmoL solution of Ab1–40:Ab1–42 10:1) or saline were bilaterally infused into the CA1 (on the first treatment day) and intraventricularly (on the following 15 days) in 6-month-old Wistar male rats."
