α-SYNUCLEIN DISRUPTS INTEGRATED SIGNALING BY THE UNFOLDED PROTEIN RESPONSE THROUGH INHIBITION OF ATF6-α INCORPORATION INTO COPII VESICLES
(Georgetown University, 2015)
Parkinson's Disease (PD) is a neurodegenerative disease characterized by the advanced loss of motor functions as a result of progressive degenerative conditions that develop in many regions of the brain and manifest as a ...
Somatostatin-GABA neurons regulate vago-vagal circuitry
(Georgetown University, 2016)
Parasympathetic regulation of the gastric antrum is mediated through the vago-vagal circuitry in which glutamatergic afferents relay peripheral information to the CNS and cholinergic efferents transmit the compensatory ...
ACTIVITY-DEPENDENT REGULATION OF AMYLOID PRECURSOR PROTEIN (APP) BY POLO-LIKE KINASE 2 (PLK2): NOVEL ROLES IN SYNAPTIC PLASTICITY
(Georgetown University, 2016)
The brain uses a special feature, synaptic plasticity, for learning and memory. As forms of synaptic plasticity, associative plasticity, long-term potentiation (LTP) and long-term depression (LTD), is a positive feedback ...
EFFECTS OF ALZHEIMER’S DISEASE GENETIC RISK FACTOR APOE4 ON THE NORMAL BRAIN
(Georgetown University, 2016)
Over 70 million Americans inherit the strongest genetic risk factor for Alzheimer’s disease (AD), the E4 allele for apolipoprotein E (APOE4), but have few strategies to reduce their risk. To identify markers associated ...
Alpha-synuclein and its direct effects on microglial activation
(Georgetown University, 2013)
Accumulation, deposition and dysfunction of α-synuclein occur in a class of neurodegenerative disorders known as synucleinopathies. These include Parkinson's disease, dementia with Lewy bodies, and multiple system ...
ELECTRIC FIELDS AND SLOW CORTICAL ACTIVITY
(Georgetown University, 2013)
Electrical activity in the brain gives rise to endogenous electric fields, which are the cause of many signals recorded from the nervous system. Electric fields can also be applied from external sources to modulate the ...
The Neurocognition of Adult Second Language Learning: An fMRI Study
(Georgetown University, 2014)
Learners achieved very high proficiency in vocabulary and reasonably high proficiency in grammar, though morphosyntactic agreement was difficult to master. FMRI activation was found in areas associated with first language ...
A-ephrins in Neuropsychiatric Spectrum Disorder Models
(Georgetown University, 2014)
Neuropsychiatric spectrum disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are frequently comorbid and exhibit overlapping abnormalities in both behavioral symptoms and ...
Functional Neuroimaging Studies of Simple Finger Movements in Healthy Development and Aging and in Children with Dyslexia
(Georgetown University, 2017)
The functional neuroanatomy of the motor system underlying finger movements has been thoroughly elucidated in young adults. However, less is known about this system at younger and older ages, and in disorders. This ...
PROTEASE INDUCED PLASTICITY: MATRIX METALLOPROTEINASE-1 ACTIVATION OF PROTEASE ACTIVATED RECEPTOR 1 INDUCES NEURONAL STRUCTURAL PLASTICITY
(Georgetown University, 2017)
The brain continues to change long after development ceases. Structural modifications to mature cells in the brain as well as the integration newborn neurons through adult hippocampal neurogenesis contribute to plasticity ...
