Distinct causal influences of parietal versus frontal areas on human visual cortex: evidence from concurrent TMS-fMRI [PDF]

, 2010
It has often been proposed that regions of the human parietal and/or frontal lobe may modulate activity in visual cortex, for example, during selective attention or saccade preparation.

The development of positron emission tomography (PET) tracer for glutamate AMPA receptors and its application to human biology and clinics

Psychiatry and Clinical Neurosciences, EarlyView.
Psychiatric and neurological disorders severely compromised patients' quality of life. Despite their urgent needs, the development of diagnostics and therapeutics based on the biological basis has made only little progress. This is due to limited evidence on the biological basis of these disorders in humans. Synapses are fundamental structural units of

Non-invasive brain stimulation lighting the human life quality’s bulb

Brain-Apparatus Communication
Non-invasive brain stimulation (NIBS) has experienced rapid development due to its non-invasive nature, convenience, and high patient compliance. Among the various NIBS techniques, transcranial magnetic stimulation (TMS) and transcranial electrical ...

Acute prefrontal hemodynamic responses to intermittent theta burst stimulation correlate with current depression and episode recurrence: A cross‐sectional study

Psychiatry and Clinical Neurosciences, EarlyView.
Background Mounting evidence has indicated that multiple major depressive disorder (MDD) episodes are correlated with brain morphometric changes that confer an increased recurrence risk. Functional abnormalities underlying this recurrent vulnerability remain underexplored.

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
