Human single-neuron activity is modulated by intracranial theta burst stimulation of the basolateral amygdala Open
Direct electrical stimulation of the human brain has been used for numerous clinical and scientific applications. At present, however, little is known about how intracranial stimulation affects activity at the microscale. In this study, we…

Direct electrical stimulation of the human amygdala enhances recognition memory for objects but not scenes Open
Summary Research from neuroscience studies using invasive neuroanatomy-inspired direct manipulations suggests the basolateral amygdala (BLA) mediates a generalized modulation of many different types of memory. In contrast, noninvasive, psy…

Human single-neuron activity is modulated by intracranial theta burst stimulation of the basolateral amygdala Open
Direct electrical stimulation of the human brain has been used for numerous clinical and scientific applications. Previously, we demonstrated that intracranial theta burst stimulation (TBS) of the basolateral amygdala (BLA) can enhance dec…

Divergence of Functional Brain Network Configurations in Same and Other Race Face Recognition Open
The “Other-Race Effect” (ORE) refers to the enhanced memory individuals have for faces within their own racial group compared to other races. This effect is attributed to limited exposure to different races and social-motivational factors …

Parsing memory and nonmemory contributions to age-related declines in mnemonic discrimination performance: a hierarchical Bayesian diffusion decision modeling approach Open
The mnemonic discrimination task (MDT) is a widely used cognitive assessment tool. Performance in this task is believed to indicate an age-related deficit in episodic memory stemming from a decreased ability to pattern-separate among simil…

Differential involvement of hippocampal subfields in the relationship between Alzheimer's pathology and memory interference in older adults Open
Introduction We tested whether Alzheimer's disease (AD) pathology predicts memory deficits in non‐demented older adults through its effects on medial temporal lobe (MTL) subregional volume. Methods Thirty‐two, non‐demented older adults wit…
View article: Posterior white matter hyperintensities are associated with reduced medial temporal lobe subregional integrity and long-term memory in older adults
Posterior white matter hyperintensities are associated with reduced medial temporal lobe subregional integrity and long-term memory in older adults Open
White matter hyperintensities are a marker of small vessel cerebrovascular disease that are strongly related to cognition in older adults. Similarly, medial temporal lobe atrophy is well-documented in aging and Alzheimer's disease and is a…
View article: Associations between saliva and plasma cytokines in cognitively normal, older adults
Associations between saliva and plasma cytokines in cognitively normal, older adults Open
Background Inflammatory responses play key roles in the development and progression of many pathological conditions, including neurodegenerative diseases. Accurate quantification of inflammatory factors in saliva would be highly advantageo…

Hippocampal volume loss is associated with PET amyloid deposition in nondemented elderly individuals Open
Background Amyloid‐beta (Aβ) plaques are among the hallmark pathologies of Alzheimer’s disease (AD) and could potentially influence the aggregation of tau pathology, which is associated with neurodegeneration in AD. Prior work has demonstr…

Do People Mentally Represent Automated Tasks? Evidence from Task-Switching Costs Following Takeovers Open
Partially automated vehicles, in which automation performs parts of the driving task, introduce new challenges of automation monitoring and human-automation teaming to the driving experience. We describe a new method for measuring whether …
