Less wiring, more firing: low-performing older adults compensate for impaired white matter with greater neural activity.
(Cereb Cortex, 2015-04)
The reliable neuroimaging finding that older adults often show greater activity (over-recruitment)
than younger adults is typically attributed to compensation. Yet, the neural mechanisms
of over-recruitment in older adults ...
Cross-hemispheric collaboration and segregation associated with task difficulty as revealed by structural and functional connectivity.
(J Neurosci, 2015-05-27)
Although it is known that brain regions in one hemisphere may interact very closely
with their corresponding contralateral regions (collaboration) or operate relatively
independent of them (segregation), the specific brain ...
Allopregnanolone Levels Are Inversely Associated with Self-Reported Pain Symptoms in U.S. Iraq and Afghanistan-Era Veterans: Implications for Biomarkers and Therapeutics.
(Pain Med, 2016-01)
BACKGROUND AND OBJECTIVES: Pain symptoms are common among Iraq/Afghanistan-era veterans,
many of whom continue to experience persistent pain symptoms despite multiple pharmacological
interventions. Preclinical data suggest ...
The frequency of involuntary autobiographical memories and future thoughts in relation to daydreaming, emotional distress, and age.
(Conscious Cogn, 2015-11)
We introduce a new scale, the Involuntary Autobiographical Memory Inventory (IAMI),
for measuring the frequency of involuntary autobiographical memories and involuntary
future thoughts. Using the scale in relation to other ...
Inhibition-Induced Forgetting Results from Resource Competition between Response Inhibition and Memory Encoding Processes.
(J Neurosci, 2015-08-26)
UNLABELLED: Response inhibition is a key component of executive control, but its relation
to other cognitive processes is not well understood. We recently documented the "inhibition-induced
forgetting effect": no-go cues ...
Is chronic asthma associated with shorter leukocyte telomere length at midlife?
(Am J Respir Crit Care Med, 2014-08-15)
RATIONALE: Asthma is prospectively associated with age-related chronic diseases and
mortality, suggesting the hypothesis that asthma may relate to a general, multisystem
phenotype of accelerated aging. OBJECTIVES: To test ...
Simultaneous transcranial magnetic stimulation and single-neuron recording in alert non-human primates.
(Nat Neurosci, 2014-08)
Transcranial magnetic stimulation (TMS) is a widely used, noninvasive method for stimulating
nervous tissue, yet its mechanisms of effect are poorly understood. Here we report
new methods for studying the influence of TMS ...
Participant, rater, and computer measures of coherence in posttraumatic stress disorder.
(J Abnorm Psychol, 2016-01)
We examined the coherence of trauma memories in a trauma-exposed community sample
of 30 adults with and 30 without posttraumatic stress disorder. The groups had similar
categories of traumas and were matched on multiple ...
A Pharmacology-Based Enrichment Program for Undergraduates Promotes Interest in Science.
(CBE Life Sci Educ, 2015)
There is a strong need to increase the number of undergraduate students who pursue
careers in science to provide the "fuel" that will power a science and technology-driven
U.S. economy. Prior research suggests that both ...
Reduced hippocampal and amygdala activity predicts memory distortions for trauma reminders in combat-related PTSD.
(J Psychiatr Res, 2011-05)
Neurobiological models of posttraumatic stress disorder (PTSD) suggest that altered
activity in the medial temporal lobes (MTL) during encoding of traumatic memories
contribute to the development and maintenance of the disorder. ...
