Heritability of human “directed” functional connectome

  • First Published: 29 March 2023
Heritability of human “directed” functional connectome

We investigated the heritability of ‘directed’ functional connections using a state-space formulation of Granger causality on resting-state functional magnetic resonance imaging data from the Human Connectome Project. The parieto-cerebellar, parieto-prefrontal, and posterior-cingulate to hippocampus connections showed the highest and most replicable heritability effects with little influence by the shared environment. In contrast, shared environmental factors significantly affected the visuo-parietal and sensory-motor directed connectivity.

We suggest a robust role of heritability in influencing the function of some cortico-subcortical circuits consistently implicated in cognition.

Impact of long-term management with sleep medications on blood pressure: An Australian national study

  • There was a strong BP-lowering effect associated with long-term management with BZD among older patients (65+ years), with 2.5 mmHg reduction in the mean SBP and 1.0 mmHg reduction in the mean DBP, compared with those not managed with BZD.
  • The average effect of short-term BZD management on BP in this age group was tenuous.
  • Our findings add evidence to current recommendations about the cautious use of long-term BZD among older patients, as their BP-lowering effect can further increase the risk of dizziness and falls in this vulnerable population.

Structural alterations of the salience network in patients with insular glioma

Structural alterations of the salience network in patients with insular glioma

In patients with insular glioma, decreased FA may lead to the destruction of the topological network within the SN, which in turn may lead to the decrease of network efficiency and brain function, and the increase of GM volume may compensate for these changes.

Associations of deep medullary veins with vascular risk factors, laboratory indicators, and cerebral small vessel disease: A population-based study

Among 1909 community-dwelling participants, DMV scores wererelated to age, male sex, body mass index, diastolic blood pressure, hypercholesterolaemia, atrial fibrillation, current drinking, total cholesterol, triglycerides, low-density lipoprotein, hemoglobin A1c, leukocytes, lymphocytes, hemoglobin, and platelets (p < .05). DMV scores wereassociated with the presence and total burden of CSVD (Rothwell's scale), modified white matter hyperintensity burden, and enlarged perivascular spaces in centrum semiovale (p < .05). However, these associations between DMV scores and CSVD disappeared after adjusting for potential confounders.

Early arrival did not ensure the early acquisition of intravenous thrombosis for acute ischemic stroke during the COVID-19 pandemic

1. Time delay due to deadline effect could have occurred in 17.2% (32/186) cases of the study, which made early arrival did not ensure early acquisition of intravenous thrombosis. 2. Behavioral and occupational factors in stroke physicians played an important role in time delay of deadline effect in intravenous thrombosis for acute stroke. 3. There was a speed-safety tradeoff between integrating more information for potential improved safety and faster response time based on information already collected under urgent time pressure of decision making for intravenous thrombosis.

Gambling on an empty stomach: Hunger modulates preferences for learned but not described risks

Our findings are the first account of how hunger differentially modulates decision-making for experienced and described risks in the same individual. We complement existing results and provide a precise index of preference change, with a formal computational model of how it might arise. This framework may be widely applicable to states of biological need, and reflect a new axis in the neurochemical and affective control of cognition.

Continuous and intermittent theta burst stimulation of primary visual cortex do not modulate resting state functional connectivity: A sham-controlled multi-echo fMRI study

We investigated the short term (up to 1 hr) effects of continuous and intermittent theta burst stimulation (TBS) to primary visual cortex on resting state functional connectivity (FC) of focal visual networks and remote brain regions. Our findings suggest that a single session of TBS to V1 does not appear to produce significant short-term alterations in functional connectivity following stimulation.

Electrocardiogram properties and risk of covert brain infarction and other magnetic resonance imaging abnormalities in a stroke-free population

Our study found that electrocardiogram abnormalities were related to presence of covert brain infarcts (CBIs), white matter hyperintensity, and sulcal atrophy on MRI in a stroke-free elderly population. Specifically, those with left axis deviation had an increased risk of presence of CBIs.Our findings suggest a potential important pathophysiologic role of heart electrical activity in the burden of silent vascular brain injury.

Investigating interindividual variability in corticomotor reorganization during sustained hamstring pain: A randomized experimental study

This was the first study to explore the variability of corticomotor responses to sustained lower limb pain. Corticomotor responses varied considerably between participants. Individuals responding with corticomotor facilitation experienced increased mechanical sensitivity compared to those responding with corticomotor depression. Our data raise the possibility that corticomotor facilitation in response to lower limb pain could indicate susceptibility to greater mechanical sensitivity and delayed return-to-play following injury.

Comparison of neurofilament light and heavy chain in spinal muscular atrophy and amyotrophic lateral sclerosis: A pilot study

Spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS) are two distinct motoneuron diseases with similar progressive symptoms and severe disability. Neurofilament light (NFL) and phosphorylated neurofilament heavy chain (pNFH) in cerebrospinal fluid might be useful biomarkers for differential diagnosis of SMA and ALS.

Seeking safety intervention for comorbid post-traumatic stress and substance use disorder: A meta-analysis

The purpose of this meta-analysis is to examine the effect of Seeking Safety (SS on PTSD and SUD across randomized control trials (RCTs) and examine the dos response. Findings suggest SS has merit in treating PTSD symptoms and substance use - SS appears more effective in reducing PTSD than substance use, which converges with the larger treatment outcome literature that consistently finds this. We explore reasons why treatment of SUD is more challenging than treating PTSD and offer suggestions for practitioners.
