Seminar: Dr Grace Lindsay

Principles of Science Writing that Can Help Your Science

Friday 15 March, 4pm at the Sherrington Library, Sherrington Building, Oxford

 

The Cortex Club is delighted to host Dr Grace Lindsay, computational neuroscientist at Columbia University, New York City, and science communicator involved in the podcast series Unsupervised Thinking and other outlets.

Dr Lindsay will be talking to us about how principles of science communication can benefit scientific thinking in an academic context. Please join us on March 15th at the Sherrington Library, located in the Sherrington Building of the Department of Physiology, Anatomy and Genetics.

If you would like to arrange a personal meeting with Dr Lindsay please contact Tai-Ying Lee at tai-ying.lee [at] dpag.ox.ac.uk or join us at the pub after the talk for an informal meeting.

 

 

Abstract

The goals of communicating science and of doing science are not directly aligned. This doesn’t mean, however, that scientists have nothing to learn from the principles of science writing. In this talk I’ll pull from established science writing principles as well as my own experience as both a scientist and science communicator to demonstrate how these principles can assist in scientific thinking. This will include ideas about doing literature research, thinking about narratives, pulling together disparate concepts, and keeping the bigger picture in mind.

Abstract

Several lines of evidence, including recent GWAS, have suggested that schizophrenia may be a disorder of impaired synaptic plasticity, particularly in the hippocampus. Traditionally, hippocampal synaptic plasticity (e.g. long-term potentiation) has been thought to subserve the formation of associative memories. Yet schizophrenic subjects are often considered to be more, rather than less, likely to form associations, which is thought to underlie the generation of their false beliefs and delusions. I will present data showing that ablating key glutamate receptor subunits involved in hippocampal synaptic plasticity (and implicated in schizophrenia) leads to deficits in a form of non-associative short-term memory that underlies the habituation of attention. This generates aberrant salience, hyperdopaminergic responses and increased theta coherence, and an increased (rather than decreased) propensity to form associations, reminiscent of what is seen in schizophrenic patients. The implications of these results for understanding synaptic homeostasis during sleep will also be discussed.

Abstract

The early auditory system decomposes incoming sounds into a collection of sine waves with different frequencies. But we would not describe our everyday experience of hearing sound as one of “perceiving frequencies”. Rather, we hear complex features such as a familiar voice or a musical melody. My research group examines how the auditory cortex integrates the frequency and timing components of sounds into more behaviourally relevant features, such as “pitch”. Pitch is our perception of the tonal quality of sounds that allows us to experience musical melody. We are using a combination of electrophysiological, behavioural and 2-photon calcium imaging techniques in ferrets to better understand how populations of auditory cortical neurons encode a sound’s pitch. Our results have provided insights into the mechanisms used by individual neurons and neural populations to produce our perception of pitch across a wide range of complex sounds. This work helps explain how we can recognize a familiar tune on a violin or piano.

Q&A: A/ Prof Theresa Burt De Perera

Navigating in a three-dimensional world

Friday 15 February, 1pm at the Large Lecture Theatre, Sherrington Building, Oxford

 

The Cortex Club is excited to presents Associate Prof Teresa Burt De Perera from the Zoology Department, Oxford, who, as part of the DPAG Head of the Department seminar series,  will be talking to us about her work on how animals deal with navigation in a three-dimensional world. Please join us on February 15th at the Large Lecture Theatre, located in the Sherrington Building of the Department of Physiology, Anatomy and Genetics.

We are hosting a Q&A session after the talk from 2.00 to 3.00 to which students and staff are warmly invited. Please sign up at: https://goo.gl/forms/S0UIVrkeKGwe9drY2

 

 

Abstract

The ability to navigate efficiently is fundamental to animals’ survival and success; enabling them to find mates, avoid predators and find their way home. To orient around their local environment, animals must recognise their own position with respect to a goal. This task can be achieved through a representation of space in their brain, built upon learning and remembering environmental features that are inputted through multiple sensory systems. A substantial research effort has sought to understand how animals navigate, but this has been focused on horizontal movement, despite the real world being three-dimensional. Indeed, most animals have some kind of vertical component to their movements, and there are both quantitative and qualitative reasons why navigating through environments with a vertical axis might be different to navigating purely in 2D. This is pushed to the extreme in volumetric environments, such as those inhabited by many fish. By using experimental and theoretical approaches, we consider how pelagic and benthic fish deal with 3D navigation; from the sensory input, to what information is learned and remembered. This not only allows us to unpick the mechanisms that underpin this important behaviour, but can also inform us about the processes behind learning and memory themselves.
