[visionlist] Postdoc position in visual systems neuroscience and high density recording throughout the brain

[Pieter Roelfsema]

Pieter Roelfsema's group at the Institut de la Vision (IDV) in Paris is seeking a highly motivated postdoctoral researcher to investigate the function and organization of the visual brain using ultra-high-channel-count neural interfaces in the macaque brain. This project aims to make significant contributions to visual neuroscience and advance the development of devices that enable large scale, high-density recording and stimulation across the macaque brain.

Understanding visual processing and the link between vision and action

The postdoctoral researcher will use ultra-high-channel-count electrode arrays to record neural activity from cortical and subcortical brain regions of macaque monkeys during behavior. We will develop a flexible high-channel-count electrode array developed in collaboration with a partner lab to measure neuronal responses to visual stimuli, and relate the activity to attention and working memory, throughout the brain. We also aim to test the effects of electrical brain stimulation and examine how their effects spread through the networks of the brain, offering new insights into the neural mechanisms of visuomotor and conscious perception (e.g. van Vugt et al., Science, 2018). This project is linked to the labs of Pieter Roelfsema at the Netherlands Institute for Neuroscience in Amsterdam and Serge Picaud at the Institut de la Vision in Paris. This is a fully funded position with possibility to acquire personal grants.

Mandatory requirements:

  *   PhD in Neuroscience, Biology, Engineering or equivalent relevant background
  *   Experience in measuring of neuronal activity in living brain tissue (electrophysiology or microscopy)
  *   Strong coding skills
  *   The candidate should be proficient in written and oral English and have experience with writing scientific texts
  *   Personal skills will be emphasized. The candidate should be able to work independently and interactively in a team setting, be motivated and responsible, and have a great work capacity and enthusiasm for research.

The ideal candidate would have additional skills, such as:

  *   Experience in training animals on behavioral tasks
  *   Analysis of large data sets
  *   Hands-on experience in new electrophysiology techniques (Neuropixels, etc)
  *   Experience in other brain recording techniques (electrophysiology, EEG, fMRI, fUS, …)
  *   Surgery and chronic implant management experience
