Effect of Chronic Stress during Adolescence in Prefrontal Cortex Structure and Function
10/01/2017
We speculate upon the risks of prolonged exposure to stressful environments in human adolescents and the possibility of stunted development of executive functions.
Asymmetry of the temporal code for space by hippocampal place cells
09/13/2017
Here we show that the spike timing of place cells couples to theta phase before major increases in firing rate, anticipating the animal’s entrance into the classical, rate-based place field.
Place and grid cells in a loop: implications for memory function and spatial coding
09/11/2017
Based on the anatomy of the entorhinal-hippocampal circuitry, we constructed a model of place and grid cells organized in a loop to investigate their mutual influence in the establishment of their codes for space.
Comparison of techniques used for functional evaluation of pelvic floor muscles
09/01/2017
Objective: To identify and discuss techniques for evaluation of pelvic floor muscles (PFM) focusing on the most used and accessible techniques in health care.
Olfactory bulb drives respiration-coupled beta oscillations in the rat hippocampus
08/22/2017
We find that beta oscillations simultaneously appear in HPC and OB and phase-lock across structures. Moreover, Granger causality analysis reveals that OB beta activity drives HPC beta.
Nasal respiration entrains delta-frequency oscillations in the prefrontal cortex and hippocampus of rodents
08/22/2017
We further showed that respiration-entrained LFP oscillations were abolished by tracheostomy and restored by rhythmic air puffing into the nasal cavity; moreover, in the hippocampus, RR had the maximum amplitude in the dentate gyrus hilus, the anatomical site where olfactory inputs impinge...
Electrophysiological evidence that the retrosplenial cortex displays a strong and specific activation phased with hippocampal theta during paradoxical (REM) sleep
08/18/2017
It is widely accepted that cortical neurons are similarly more activated during waking and paradoxical sleep (PS, aka REM) than during slow wave sleep (SWS).
Unveiling Fast Field Oscillations through Comodulation
08/07/2017
Comodulation analysis unveils four different types of fast LFP activity coupled to theta: two oscillations within the traditional gamma band, HFOs, and spike-leaked activity.
