Advancements in multielectrode recording techniques in neurophysiology: From wire probes to Neuropixels
Join us for a comprehensive introduction to multielectrode recording technologies for in vivo neurophysiology. Whether you are new to the field or have experience with one type of technology, this webinar will provide you with information about a variety of technologies, with a main focus on Neuropixels probes.
Partnering with the BNA, this webinar will take place on Thursday 12th August, 5-6pm BST and is free of charge.
Dr Kris Schoepfer, US Product Specialist at Scientifica, will provide an overview of multielectrode technologies available to record from one or more brain areas simultaneously, including:
- DIY multielectrode probes
- Tetrodes / Hyperdrives
- Silicon probes
Keynote speaker, Dr Sylvia Schröder, University of Sussex, will delve deeper into the advantages of Neuropixels, highlighting the value of channel depth and the types of new biological insights that can be explored thanks to the advancements this technology brings. Presenting exciting data from the optic tract and superior colliculus, Sylvia will also discuss how Neuropixels recordings can be combined with optogenetics, and how histology can be used to identify the location of probes.
About Dr Sylvia Schröder
Sylvia obtained a Bachelor in Cognitive Science from University of Osnabrueck (Germany). Her interests in neural mechanisms then led to a Master in Neural Systems and Computation at the Institute of Neuroinformatics in Zurich (Switzerland). In the lab of Kevan Martin, she used electrophysiology to study the functional diversity of neighbouring neurons in cat primary visual cortex. The surprising differences of neurons’ responses to natural visual stimuli, sparked Sylvia’s interest in the relevance of neural codes during natural behaviour.
With the support of a Marie Curie Fellowship, Sylvia joined the Cortex lab of Matteo Carandini and Kenneth Harris at UCL (UK) to study how behaviour affects early visual processing in the retina and the superior colliculus. Using two-photon imaging and Neuropixels probes in mice, she discovered that retinal output and the activity of downstream neurons are modulated by the animal’s level of arousal and its running speed.
Since January 2021, Sylvia is a Sir Henry Dale Fellow and Group Leader at the University of Sussex. She will continue to use two-photon imaging and high-density electrophysiology recordings with Neuropixels probes to investigate the purpose and the mechanism of the behavioural modulation in the early visual system.
