“Why serotonin is critical for brain development”

 My talk on serotonin will cover 5 main points.

 1)  Serotonin is being utilized by the sensory system during early development

2)   Early manipulation of serotonin either via drug application or genetic mutation may alter sensory function and even global network function

3)   Axonal myelin maturation and oligodendrocyte integrity is also affected by serotonin

4)   Activation of immune cells such as microglia can be induced by early manipulation of serotonin

5)   Intense early auditory training has the ability to reverse such deficits

"Neural circuits underlying pattern completion"

Our brains must continually make cognitive inferences based on putting together information from different sources to orchestrate perceptions, decisions and behavior. The mechanisms underlying such integrative processes are critical to cognition. In this talk, I will discuss the magic behind pattern completion in the context of visual recognition. Recognition of objects from partial information presents a significant challenge for theories of vision because it requires spatial integration, extrapolation from prior knowledge and inference. I will present invasive neurophysiological recordings from the human ventral visual and psychophysical measurements during object completion. Responses along the ventral visual stream remained selective despite showing only a small fraction of objects. These visually selective signals emerged ~100 ms later for partial versus whole objects, consistent with similar behavioral delays that accompany object completion. Computational modeling shows that the performance of a family of purely bottom-up architectures is significantly impaired by heavy occlusion and that this effect can be partially rescued via the incorporation of top-down and/or recurrent connections. These results provide spatiotemporal constraints on theories of object recognition that involve recurrent processing to recognize objects from partial information and take initial steps towards elucidating how neural circuits can implement intelligent inference.

Professional Development Colloquium Series presents Vicki Ahlstrom
March 20, 2015

Careers with the US Government: A Professional Development Workshop for Graduate Students and Postdoctoral Fellows in Psychological Sciences and Neuroscience

 Vicki Ahlstrom, Engineering Research Psychologist Federal Aviation Administration (FAA)

Friday March 20, 2015, 115 Wilson Hall, 4:00-6:00 p.m.

Vicki Ahlstrom is an Engineering Research Psychologist and Technical Lead for the Federal Aviation Administration (FAA) in the Human Factors Branch at the William J. Hughes Technical Center in Atlantic City. She is responsible for research and standards development related to air traffic systems. Vicki was in the graduate program in Psychology at Vanderbilt from 1992-1997 under the guidance of Randolph Blake. In addition to talking specifically about her own career path and past and present job responsibilities working for the FAA, she will talk in general about some of the kinds of jobs available for those with graduate degrees in psychology and neuroscience with federal government agencies, careers in government, how jobs are advertised, how job applicants are evaluated, and general tips when considering this possible career path.
