Intracranial pressure affects somatosensory cortex.

Link – Elevation of intracranial pressure affects the relationship between hemoglobin concentration and neuronal activation in human somatosensory cortex. Abstract During neuronal activation, a local decrease of deoxygenated hemoglobin concentration (deoxy-Hb) occurs which is the basis of functional brain imaging with blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI). Elevated intracranial pressure (eICP) has […]

Modifiability of resting-state brain network complexity

Link – The functional implications and modifiability of resting-state brain network complexity in older adults. Neurosci Lett. 2020 Jan 20;:134775 Authors: Zhou J, Lo OY, Halko MA, Harrison R, Lipsitz LA, Manor B Abstract The dynamics of the resting-state activity in brain functional networks are complex, containing meaningful patterns over multiple temporal scales. Such physiologic […]

tACS modulation of BOLD signal

Link – Frequency-dependent tACS modulation of BOLD signal during rhythmic visual stimulation. Hum Brain Mapp. 2018 05;39(5):2111-2120 Authors: Chai Y, Sheng J, Bandettini PA, Gao JH Abstract Transcranial alternating current stimulation (tACS) has emerged as a promising tool for modulating cortical oscillations. In previous electroencephalogram (EEG) studies, tACS has been found to modulate brain oscillatory […]
