Personalized alpha-tACS targeting left posterior parietal cortex modulates visuo-spatial attention and posterior evoked EEG activity

Brain Stimulation, 2023
Background: Covert visuo-spatial attention is marked by the anticipatory lateralization of neuronal alpha activity in the posterior parietal cortex.

Converging Structural and Functional Connectivity of Orbitofrontal, Dorsolateral Prefrontal, and Posterior Parietal Cortex in the Human Striatum

Journal of Neuroscience, 2014
Modification of spatial attention via reinforcement learning (Lee and Shomstein, 2013) requires the integration of reward, attention, and executive processes.

The Relationship between Rest Tremor and Underlying Lewy Pathology in Essential Tremor: A Clinical‐Pathological Study of 201 Cases

Annals of Neurology, EarlyView.
Objectives Prospective studies demonstrated that essential tremor is a risk factor for Parkinson's disease. Identifying clinical markers for conversion from essential tremor to essential tremor‐Parkinson's disease would be of considerable value. Rest tremor can be present in advanced essential tremor and may be a harbinger of conversion. We examined (1)

Integration of Visual and Proprioceptive Limb Position Information in Human Posterior Parietal, Premotor, and Extrastriate Cortex

Journal of Neuroscience, 2016
The brain constructs a flexible representation of the body from multisensory information. Previous work on monkeys suggests that the posterior parietal cortex (PPC) and ventral premotor cortex (PMv) represent the position of the upper limbs based on ...

Mapping Postictal Aphasia through Signal Complexity: A Stereo‐Electroencephalography Study

Annals of Neurology, EarlyView.
Objective The postictal period provides an opportunity to investigate the pathophysiology underlying aphasia and recovery following epileptic seizures. This study examines postictal aphasia in stereo‐electroencephalography (SEEG)‐explored patients to identify brain regions associated with task‐specific language deficits using signal complexity analysis.

Sex Differences in Associations of Lewy Body Disease with Alzheimer's Disease and Cognitive Decline

Annals of Neurology, EarlyView.
Objective To investigate how sex and age at menopause influence the interplay between Alzheimer's disease (AD) and Lewy body disease (LBD) neuropathologies, and their associations with cognitive decline. Methods We analyzed data from: (1) three Rush Alzheimer's Disease Center cohorts (i.e., the Religious Orders Study, Rush Memory and Aging Project, and

Common neural substrate for processing depth and direction signals for reaching in the monkey medial posterior parietal cortex.

Cerebral Cortex, 2014
Many psychophysical studies suggest that target depth and direction during reaches are processed independently, but the neurophysiological support to this view is so far limited.

Resting state functional thalamic connectivity abnormalities in patients with post-stroke sleep apnoea: a pilot case-control study [PDF]

, 2017
OBJECTIVE: Sleep apnoea is common after stroke, and has adverse effects on the clinical outcome of affected cases. Its pathophysiological mechanisms are only partially known.

Subthalamic Electrophysiological Mapping of Gait Initiation Dynamics and Freezing in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The objective of this study was to investigate the relationships among subthalamic nucleus (STN) activity, gait initiation (GI), and freezing of gait (FOG) in patients with Parkinson's disease (PD). Methods We recorded GI and STN local field potentials (LFPs) via externalized cables in 38 patients with PD (35 reporting FOG in daily life ...
