- Description:
- Stimulus generalization is a critical mechanism for facilitating behavioral flexibility. Generalization allows the brain to reduce computational demands that would otherwise be necessary to create unique representations for each and every encounter while allowing the ability to deal with the complexity of real-world situations. Stimulus generalization is a fundamental cognitive...

- Description:
- Herpes simplex virus (HSV) encephalitis (HSE) is the most common cause of sporadic fatal encephalitis, and despite targeted antiviral therapy, outcomes remain poor. While rare in adults, neonates are significantly more susceptible to severe HSV disease. Understanding both the host and viral factors that contribute to pathogenesis is critical to...

- Description:
- SCN2A encodes the NaV1.2 voltage-gated sodium channel, which is thought to contribute to the development of the central nervous system. Pathogenic variants in SCN2A have been associated with neurodevelopmental disorders (NDD), including developmental and epileptic encephalopathies (DEE), intellectual disability (ID), and autism spectrum disorder (ASD). These disorders represent a significant...

- One of the most fascinating observations in the brain is that the neural connections change with experience and this phenomenon is called synaptic plasticity. Patterns of activity or neuromodulators can acutely induce changes in the synaptic strength in the brain. My thesis is focused on understanding the mechanisms of plasticity...

- Description:
- The basal ganglia operate largely in closed parallel loops, including an associative circuit for goal-directed behavior originating from the dorsomedial striatum (DMS) and a somatosensory circuit important for habit formation originating from the dorsolateral striatum (DLS). An exception to this parallel circuit organization was proposed to explain how information is...

- Understanding associative memory is fundamental for a variety of neurological and neurodegenerative diseases, however, a large proportion of this research has excluded female subjects due to unsubstantiated bias. By including intact females, ovariectomized females and males in the study of associative memory, clear sex differences in acquisition emerged. Female mice...

- Breast cancer patients have reported nonspecific neurologic symptoms such as fatigue, depression, and cognitive concerns while undergoing adjuvant therapy. Few neuroimaging studies have examined hormone therapy, an adjuvant therapy, and more research is needed to determine possible neurologic and cognitive effects. Previous estrogen research has found alterations in gray matter...

- Description:
- We perform many movements every day without much deliberation. However, moving can be seen as a form of decision-making since one of many possible movements must be selected and executed. The decision-making processes that underlie movements are influenced by various factors, including sensory perception, energetics, time, perceived rates of failure...

- Description:
- We present two ways in which measures of information can be used for the design and analysis of neural networks in both the brain and the computer. In the brain, stimulus is often represented as a distributed pattern of activity in a network of neurons. The quality of such population...

- Description:
- Identifying key molecular mechanisms and targets for therapeutic development in sporadic neurodegenerative diseases has been challenging. Therefore, in-depth investigation of genetic forms of disease can provide valuable insight into pathogenic disease mechanisms. The discovery of genetic forms of Parkinson’s disease (PD) has highlighted the importance of the autophagy/lysosomal and mitochondrial/oxidative...

- Description:
- Vertebrate brains evolved to facilitate a diverse array of behaviors and internal cognitive processes. Theories of neural function have proposed that neural computation is organized within populations or ensembles of neurons. Here, we identify ensembles of neurons in the striatum, the main input nucleus of the basal ganglia, in which...

- Description:
- Recent studies have begun to examine white matter connectivity aberrations in psychiatric populations, such as major depressive disorder. Several studies have found reduced white matter integrity (WMI) in depressed samples, though the location of this reduction is not clear. Incorporating symptom measures of depression severity and rumination may allow for...

- Description:
- New neurons are continuously produced in the subgranular zone of the dentate gyrus of the hippocampus throughout life. These newborn dentate granule cells (DGCs) undergo a stereotyped process of morphological and functional maturation during the first few weeks after differentiation that recapitulates some aspects of postnatal neuronal development. The inhibitory...

- Description:
- Frontotemporal Dementia (FTD) and Amyotrophic Lateral Sclerosis (ALS) are two devastating neurodegenerative diseases that affect 100,000s of people globally. They have a severe adverse impact on society, yet there are currently no early diagnostic tools or disease-modifying therapies available. Despite their clinical heterogeneity, evidence points to these diseases being on...

Thus, all organisms must have the capacity to detect and respond to external temperature. Thermosensation endows animals with the ability to sense and respond...

- Glioblastoma multiforme (GBM) is the most prevalent primary central nervous system tumor, characterized by resistance to therapeutic intervention, inevitable recurrence, and ultimately patient death. The dismal prognosis is due in part to underlying molecular factors that promote an intratumoral cellular state heterogeneity and protect tumor cells from cell death pathways....

In animal models, particularly dense olfactory inputs have been shown to target orbitofrontal cortex (OFC), a region involved in multimodal sensory integration, reward coding, and flexibly guiding our...

Here, I show that the avoidance of hot temperature, a simple innate behavior, contains unexpected plasticity and complex processing...

- Protein homeostasis, or proteostasis, is essential for preserving all cellular functions and involves a balance of protein synthesis, folding, trafficking, and degradation. A collapse in proteostasis is a common feature of many neurodegenerative disorders that are characterized by the accumulation of insoluble protein aggregates in the brain. Parkinson’s disease (PD)...
