GSA 2010: an eye-opening experience

What happens when you organize a conference based on a population rather than a field of study? Everybody gets an eye-opening experience! At the end of November, members of Brandeis Psychology and Neuroscience community presented research at the 63rd annual Gerontological Society of America conference. Members from Art Wingfield’s Memory and Cognition Lab, Derek Isaacowitz’s Emotion Lab, and Margie Lachman’s Lifespan Developmental Psychology Lab all presented research at this conference.
This conference includes research on a wide area of aging topics from many different disciplines: behavioral and social sciences, health sciences, biological sciences, and social policy and practice.

To give an idea of the variety of ideas discussed at the conference, here is a sampling of session titles:

  • “Introduction to medicare part d data for research”
  • “Differences in Stroke Care Settings: Findings from the Patient Preference for Stroke Study”
  • “Age-related Differences and Similarities in Learning and Memory”
  • “Followed to extinction: Predictors of exceptional Survival in Very Long Term Cohort Studies”
  • “Composition Changes and Muscle Function: Targets for Preserving Health and Function”

This conference allowed members of the Brandeis scientific community to share their research with peers in their field and members of their academic family, as well as scientists and professionals from other fields. Although sharing research with your peers is always a productive experience, interacting with those from completely other fields also proved to be an invaluable exercise. It allowed attendees to be reminded of the assumptions that are made within any given discipline or paradigm, and allowed practice in communicating results to a broader audience.

All of this took place in the great city of New Orleans. The Cajun was music and food was enjoyed by many, and a great great time was had by all!

Re-vamped course for Spring 2011 — PSYC 213a: Social Neuroscience and Culture

This course combines two current topics in Psychology, exploring how the social interactions of humans are processed by the brain and the ways that culture can shape social, as well as cognitive, processes.  Topics include the self, stereotyping, empathy, neuroeconomics, and biculturalism.  In addition to a focus on fMRI research, Dr. Janelle Beadle, a postdoctoral trainee in Neuroscience, will serve as a co-Instructor, lending her expertise in patient research.

Previously taught three years ago as PSYC 180a, this course has been re-listed as a graduate course (although advanced undergraduates are welcome to enroll, pending instructor approval) to allow for more hands-on work, such as the design of cross-cultural research studies.  Prof. Angela Gutchess notes that both social neuroscience and cross-cultural research (and even “cultural neuroscience”, the combination of the two) have grown tremendously in the short time since the course was last offered, and that she is particularly excited to be teaching this course upon return from her semester in Istanbul, Turkey as a Fulbright Scholar.

Control beliefs, social support, and physical exercise are probably good for you

In a paper recently publised in PLoS One entitled Promoting functional health in midlife and old age: long-term protective effects of control beliefs, social support, and physical exercise, Margie Lachman, Minnie and Harold Fierman Professor of Psychology, and Brandeis postdoc Stefan Agrigoroaei analyzed data from MIDUS, a national longitudinal study of “Midlife in the US”. Controlling for other risks, the authors found significant positive contributions from three additional factors in the functional health outcome in these older adults:

  1. Control beliefs (the perception that one can influence what happens in one’s life)
  2. Social support (feeling support, not strain, in relationships with family, friends, and spouse)
  3. Physical exercise

Since I’ll be healthier if I believe I can control my health this way, why not give it a try? The popular press is also picking up on these ideas.

The Contribution of Childhood Trauma to the Neurobiology of Depression

On Thursday, Oct 28th at 3:30, Christine Heim, PhD, will speak in the Martin Weiner Lecture Series on the Psychology of Aging and the Brain, Body & Behavior program. Her presentation The Contribution of Childhood Trauma to the Neurobiology of Depression will take place in Levine Ross, Hassenfeld.
She will talk about how early life experiences, in particular childhood trauma, can have a long-lasting impact on human biology and psychology. Her research shows for example that childhood trauma can lead to specific neuroendocrine changes and contribute to the development of depression with a specific, biologically distinguishable profile, that is responsive to different types of treatment than other subtypes of depression.
Christine Heim is Associate Professor in the Department of Psychiatry and Behavioral Sciences, Emory University School of Medicine, Atlanta, GA.
There are still some time slots available for meeting with Christine on Thurday (between 1pm and 3pm). Please contact Nicolas Rohleder if you’re interested!

How long does it take the brain to access short-term memory?

A recent paper in Neuroimage by Brandeis Neuroscience Ph. D. program alumnus Yigal Agam, Professor Robert Sekuler and coworkers attempts to answer the question. To identify the earliest neural signs of recognition memory, they used event related potentials collected from human observers engaged in a visual short term memory task.  Their results point to an initial feed-forward interaction that underlies comparisons between what is being current seen and what has been stored in memory.  The locus of these earliest recognition-related potentials is consistent with the idea that visual areas of the brain contribute to temporary storage of visual information for use in ongoing tasks. This study provides a first look into early neural activity that supports the processing of visual information during short-term memory.
