THE BRI WELCOMES TW0 NEW MEMBERS
Two new members, Dr. Hugh T. Blair, Assistant Professor of Behavioral Neuroscience in the Department of Psychology, and Dr. Juan Carlos G. Marvizón, Assistant Professor of Medicine, Division of Digestive Diseases recently joined the Brain Research Institute.
Hugh T. Blair received a Ph.D. degree in behavioral neuroscience from Yale University in 1998. He then completed a postdoctoral fellowship in the laboratory of Dr. Joseph LeDoux at New York University Center for Neural Science. In 2002, Dr. Blair joined UCLA’s Department of Psychology as an Assistant Professor of Behavioral Neuroscience.
Describing his current investigations, Dr. Blair states, “My research combines experimental neurophysiology with theoretical modeling to investigate basic principles of neural computation in the nervous system. I am particularly interested in understanding how learning alters nerve cells and synapses to form memories, and how these cellular changes are ultimately responsible for changes in behavior. The primary method that I use to address these questions in my research is to record neural activity from awake, behaving rats while they are actively engaged in learning tasks. For example, to study the neural basis of long-term memory storage, I record neurons from the hippocampus and amygdala during aversive conditioning tasks, because these brain structures rapidly store long-lasting memories of aversive events. To study short-term memory mechanisms I record neurons called head-direction cells from the anterior thalamus and limbic cortex because these neurons implement a simple short-term working memory circuit that maintains an online representation of the rats’ directional heading. Based on the results of these neurophysiology experiments, I try to develop computational models to explain how specific neural circuits participate in storing new memories, retrieving old memories, and making behavioral decisions.”
Juan Carlos G. Marvizón received a Ph.D. degree in biochemistry from the Universidad Autónoma de Madrid, Centro de Biología Molecular, Madrid, Spain, in 1985. Upon completion of his degree, Dr. Marvizón moved to Gennevilliers, France to join Pharmuka Laboratories as a researcher in the pharmaceutical company. In 1986, Dr. Marvizón was the recipient of a Fulbright and Fogarty Fellow, and joined the Laboratory of Neuroscience at the National Institute of Diabetes, Digestive and Kidney Disease, NIH, Bethesda, Maryland. In 1989, Dr. Marvizón returned to the Universidad Autónoma de Madrid, and served as “Profesor Titular,” in the Departmento de Biología Molecular until coming to the United States in 1991. From 1991 to 1993, Dr. Marvizón served as research assistant professor in the Department of Biological Sciences at the University of Southern California. Dr. Marvizón joined UCLA in 1994, and is currently an Assistant Professor of Medicine in the Division of Digestive Diseases.
Describing his research interests, Dr. Marzivón states, “My research field is the neurophysiology of pain and analgesia, and the overall goal of my work is to investigate cellular and molecular mechanisms that mediate central sensitization in the spinal cord. Central sensitization, a process that underlies numerous chronic pain disorders, results in the long-term increase of nociceptive signals that reach the spinal cord and are then sent to higher regions of the CNS where they become conscious pain sensations. Recent discoveries have revealed the important role played by substance P and its receptor, the neurokinin 1 receptor, in mediating central sensitization. On the other hand, endogenous opioid peptides released in the spinal cord may be the natural way for the body to reverse central sensitization. I have developed a new methodology which measures the activation of neuropeptide receptors by their internalization. Most G protein-coupled receptors are internalized after agonist binding, and this internalization can be detected using antibodies against the receptor. Thus, if a given stimulus produces receptor internalization, it can be inferred that it has elicited the release of endogenous agonists that activate that receptor. In my laboratory we use electrophysiology techniques to deliver precise electrical stimulation to spinal cord slices or to live animals while performing intracellular and axonal recordings to monitor neuronal activity evoked by the stimulation. We have recently started to study animal behavioral responses to pain as well, using standard tests like the tail-flick test to measure analgesia. This multidisciplinary approach allows us to map the neuronal circuitry and characterize the pharmacological properties of the signaling systems that activate opioid receptors and substance P receptors in the spinal cord”
The Brain Research Institute is happy to welcome its newest members.

The National Neurological Research Specimen Bank and the Multiple Sclerosis Human Neurospecimen Bank, located at VA West Los Angeles Healthcare Center, maintains a collection of quick frozen and formalin fixed postmortem human brain tissue and frozen cerebrospinal fluid (CSF) from patients with neurological diseases (including Alzheimer's Disease, amyotrophic lateral sclerosis, depressive disorder/suicide, epilepsy, Huntington's disease, multiple sclerosis, Parkinson's Disease, progressive supranuclear palsy, schizophrenia, stroke/CVA and other less common diseases). Full inventory is available upon request. Diagnoses are documented by clinical medical records and gross/microscopic neuropathology.
Special features of the Bank are as follows:
1). Serial digital images of coronal sections (7 mm thick and obtained before quick freezing) are available for selecting samples to be studied.
2). Microscopic neuropathology is available on each dissected sample and the dissected sample's localization is sketched on the gross coronal section image from which it came.
3). Plaques of demyelination are classified as active, chronic active or inactive, and a shipment includes adjacent normal appearing white and nearby gray matter from the same case (they serve as a type of control).
4). Ice artifact is minimized and it does not interfere with in situ hybridization or in situ PCR or immunocytochemistry.
5). Tissue samples have been used for harvesting enough mRNA for microarray assay plates.
6). CSF cells and cell-free CSF are available pre- and postmortem as is serum, plasma and buffy coats. They are stored quick frozen (full inventory is available upon request).
