Frequency and Intensity of Electrical Stimulation of Human Sympathetic Ganglia Affect Heart Rate Variability and Pain Threshold

Applied Sciences, 2019
The study relates to the selection of effective clinical treatments based on the changes associated with each electrical stimulation condition. The aim was to investigate the effects of electrical stimulation on the autonomic nervous system by evaluating

The Anatomy of the Basal Ganglia [PDF]

, 2016
The basal ganglia are a set of subcortical nuclei that receive inputs from the entire cortex and send outputs via the thalamus to different frontal cortical areas. Several parallel and segregated closed cortico-striatal-thalamo-cortical loops serve a role in selecting desirable actions and suppressing undesirable ones.

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

How Laminar Frontal Cortex and Basal Ganglia Circuits Interact to Control Planned and Reactive Saccades [PDF]

, 2000
The basal ganglia and frontal cortex together allow animals to learn adaptive responses that acquire rewards when prepotent reflexive responses are insufficient.

Associative memory stored by functional novel pathway rather than modifications of preexisting neuronal pathways [PDF]

, 2006
Associative conditioning involves changes in the processing pathways activated by sensory information to link the conditioned stimulus (CS) to the conditioned behavior.

Compound Heterozygous MRPS14 Variants Associated With Leigh Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT MRPS14 (uS14m) is a nuclear‐encoded ribosomal protein important for mitochondria‐specific translation. To date, only a single individual with a recessive MRPS14‐related disorder (also known as COXPD38) has been reported. We report an additional subject possessing novel compound heterozygous MRPS14 variants (p.Asp37Asn, p.Asn60Asp). The subject

Rodent models of impulsive–compulsive behaviors in Parkinson's disease: How far have we reached?

Neurobiology of Disease, 2015
There is increasing awareness that the medications used to treat the motor symptoms of Parkinson's disease (PD) contribute to the development of behavioral addictions, which have been clinically defined as impulsive–compulsive behaviors (ICBs).

Serotonergic and Dopaminergic Function in Neuropsychiatrically Asymptomatic People With HIV on Antiretroviral Therapy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with HIV (PWH) on antiretroviral therapy (ART) still experience neurocognitive dysfunction and accelerated brain volume loss. To assess whether the serotonergic and dopaminergic systems are affected, we used [11C]DASB positron emission tomography (PET) to assess presynaptic serotonergic function and [18F]FDOPA PET to measure ...

Migration and maturation pattern of fetal enteric ganglia: A study of 16 cases

Indian Journal of Pathology and Microbiology, 2011
Aims: To study the migration and developmental pattern of ganglion cells in fetuses aged 9-21 weeks, and to document whether the migration was occurring circumferentially equally in the entire axis or if there were discrepancies in different portions at ...
