Seeing things both ways: how the visual system chooses between equivalent states

(This talk is a preliminary job-style talk, feedback encouraged!)

Though seeing the world feels effortless, perception is an active process through which a useful interpretation of the visual environment is created. In its construction of reality, our brains combine sensory information with our goals and expectations, all of which contribute to our visual experiences. However, this process does not always have a clear resolution – at times our visual system encounters information consistent with more than one plausible interpretation. Such scenarios can result in what is known as multistable vision, during which one’s visual experience alternates back-and-forth between the available options without ever settling on a definitive solution. By focusing on a particular instance of multistable vision (known as binocular rivalry) that arises when the left and right eye view drastically different images, my research seeks to unravel the complex interplay of visual mechanisms responsible for the alternate selection of perceptual interpretations. One particular focus has been on the role of visual attention, which appears essential for driving the typical dynamics of binocular rivalry and yet holds only modest sway over which interpretation will dominate. To understand this seemingly contradictory pattern, I have studied the interactions between visual attention and the mechanisms of binocular vision to understand what underlies this attentional limitation. These results have shed light on the processes that merge the images in our left and right eyes into a single percept, and have exposed critical factors that drive the efficacy of visual attention’s influence.

"What marsupials tell about the evolution of mammalian brains"

In the effort to understand the evolution of mammalian brains, we have found that common relationships between brain structure mass and numbers of non-neuronal (glial and vascular) cells apply across eutherian mammals, but brain structure mass scales differently with numbers of neurons across structures and across primate and non-primate clades. This suggests that the ancestral scaling rules for mammalian brains are those shared by extant non-primate eutherians – but do these scaling relationships apply to marsupials, a sister group to eutherians that diverged early in mammalian evolution?

We examined the cellular composition of the brain of ten species of marsupials. We showed that brain structure mass scales with numbers of non-neuronal cells, and numbers of cerebellar neurons scale with numbers of cerebral cortical neurons, comparable to what we have found in eutherians. These shared scaling relationships are therefore indicative of mechanisms that have been conserved since the first therians. In contrast, while marsupials share with non-primate eutherians the scaling of cerebral cortex mass with number of neurons, their cerebella have more neurons than non-primate eutherian cerebella of similar mass, and their rest of brain has fewer neurons than eutherian structures of similar mass. Moreover, Australasian marsupials exhibit ratios of neurons in the cerebral cortex and cerebellum over the rest of the brain, comparable to artiodactyls and primates.

Our results suggest that Australasian marsupials have diverged from the ancestral Theria neuronal scaling rules, and support the suggestion that the scaling of average neuronal cell size with increasing numbers of neurons varies in evolution independently of the allocation of neurons across structures.

Detecting Intervention Effects in a Cluster Randomized Design

using Multilevel Structural Equation Modeling for Binary Responses

 

Multilevel modeling (MLM) is frequently used to detect group differences, such as an intervention effect in a pre-test-post-test cluster-randomized design. Group differences on the post-test scores are detected by controlling for pre-test scores as a proxy variable for unobserved factors that predict future attributes. The pre-test and post-test scores that are most often used in MLM are summed item responses (or total scores). In prior research, there have been concerns regarding measurement error in the use of total scores in using MLM. To correct for measurement error in the covariate and outcome, a theoretical justification for the use of multilevel structural equation modeling (MSEM) has been established. However, MSEM for binary responses has not been widely applied to detect intervention effects (group differences) in intervention studies. In this talk, the use of MSEM will be demonstrated for intervention studies. Further, the consequences of using MLM instead of MSEM will be discussed in detecting group differences.

The Program for Music, Mind & Society at Vanderbilt: Annual Symposium
September 12, 2016

The Program for Music, Mind & Society at Vanderbilt announces a Call for Poster Abstracts for our Annual Symposium on September 12, 2016. Additionally, the Program is happy to announce that registration is now open. Please share the following information widely within your department and with other colleagues.

Proposal Submission Information:

Abstract content: Brief abstracts (100 words) should summarize one or more research projects related to systematic and scientific study of how music works in the mind and/or in society.  Poster content should be targeted to a broad scientific audience; as such, some posters may include data, while others may describe an emerging line of research. Both are encouraged. 

Who can submit: Submissions are welcome from the Vanderbilt community as well as other institutions. Cross-disciplinary work is encouraged, including but not limited to submissions from the fields of Education, Psychology, Neuroscience, Communications, Medicine, Music, and Sociology.  

How to submit an abstract: Submit your abstract online here until Friday, July 22.

Presentation guidelines: At least one representative from each poster should be available to present at the poster session during the symposium. 

Registration: You do not need to present in order to attend! We do ask that all attendees (including presenters) register at this link: https://is.gd/MMSregistration. There is no cost to register for the symposium. Registration allows us to calculate an accurate headcount so that we can plan appropriately for supplies, food, A/V needs, etc. So we greatly appreciate you registering in advance.

More event details, including lodging information is on the symposium website.

Key dates:

Poster Abstract Submission Deadline:   Friday, July 22

Symposium registration deadline:         Tuesday, September 6

Event date:                                         Monday, September 12 

Event Leadership:

Program Chair, Sara L. Beck, PhD candidate, Program for Music, Mind & Society at Vanderbilt

Symposium Chair, Reyna L. Gordon, PhD, Director, Music Cognition Lab, Vanderbilt University Medical Center

Questions/Mailing list:

Contact VanderbiltMMSEvents@gmail.com with questions.

If you are interested in keeping abreast of all Program for the Music, Mind & Society at Vanderbilt events or updates, please join their list serv. To do so, e-mail MUSICANDBRAIN@LIST.VANDERBILT.EDU and ask to be added to the Music and Brain listserv.
