Neuroscience Seminar: Targeting the Ventral Pallidum to Modulate Compulsive Behavior
Research in Dr. Creed's lab focuses on how chronic pain, stress and addictive drugs induces changes in neural circuits that underlie symptoms of psychiatric disorders. The lab uses a range of techniques including in vivo and patch clamp electrophysiology, genetic sequencing, neuroanatomy, optogenetics and behavior to study changes in function in the ventral basal ganglia in models of addiction, mood and chronic pain disorders. The main goal of the lab is to leverage insight from circuit studies to develop novel neuromodulation therapies for these disorders, including deep brain stimulation (DBS) and targeted drug delivery ...

NIH Director's Seminar Series: Hypothalamic cell types and circuits that drive survival behaviors
The Aponte lab studies the role of genetically-identified neurons and their projections in behaviors that are essential for survival. Their ultimate goal is to understand how neurons in distinct hypothalamic circuits encode pain and the rewarding and addictive nature of food intake. To answer these questions, they use a combination of optogenetics, chemogenetics, electrophysiology, two- and single-photon fluorescence endomicroscopy, and behavioral assays to manipulate and measure the activity of these genetically-defined neuronal subpopulations in awake behaving mice. Recently, they showed how two of the lateral hypothalam...

NIH Director's Seminar Series: Long-range synaptic and local receptor-mediated control of dopaminergic neuron excitability – dendrites, soma and axons
Dopamine-releasing neurons located in the midbrain play a central role in reward and motor learning behaviors. Their dysfunction is implicated in an array of disorders from addiction to Parkinson ’ s Disease (PD). The Cellular Neurophysiology Section headed by Dr. Zayd Khaliq examines the circuit, synaptic and intrinsic mechanisms that contribute to the firing patterns that underlie dopamine-dependent behaviors. The first part of the lecture will discuss the ionic and modulatory mechanisms of firing patterns observed in dopaminergic neurons of the substantia nigra during aversive behaviors. Axons of dopaminergic neurons ...

NLM ADA Lovelace Lecture: Tackling Diabetic Retinopathy in a Safety Net Healthcare Setting with Telehealth and Machine Learning
NLM ADA Lovelace Lecture
Diabetic retinopathy is the leading cause of blindness in working age adults in the United States. It is challenging to address in both rural and urban underserved settings, which suffer from shortages of eye specialists. This talk will describe the approach taken to address this condition in a medically underserved area (South Los Angeles) by researchers in the Center for Biomedical Informatics at Charles R. Drew University of Medicine and Science, using telehealth and machine learning on data from patient electronic health records.

Neural Representations of Social Homeostasis
Speaker Kay Tye, Ph.D., is Professor, Systems Neurobiology Laboratory; and Wylie Vale Chair, Salk Institute. Tye ’ s lab seeks to understand the neural-circuit basis of emotion that leads to motivated behaviors such as social interaction, reward-seeking and avoidance. Her lab employs a multidisciplinary approach including cellular-resolution recordings, behavioral assays and optogenetics, a technique that activates certain cells with light, to find mechanistic explanations for how these emotional and motivational states influence behavior in health and disease.For more information go tohttps://oir.nih.gov/walsAir date: 1...
