International Brain Laboratory

Last updated

The International Brain Laboratory (IBL) is a collaborative research group that aims to develop the first global model of decision making in mice. [1] [2] In its first phase, IBL members are recording 100,000's of neurons across virtually all brain structures in mice performing the very same decision. IBL was officially launched in September 2017 [3] [4] thanks to a $10 million grant from Simons Foundation and a £10 million grant from the Wellcome Trust.

Contents

The first major scientific milestones for the project are the development of an open source data architecture for large scale neuroscience collaboration [5] and the replication of the behavior across all experimental labs. [6] In late 2019, the IBL released the behavioral data, containing close to 3 million mouse choices. [6] The subsequent milestone involves the assembly of a brain-wide map of activity. This map of activity is being obtained with Neuropixels probes, which allow recording up to 300-1000 neurons simultaneously. [7] Other recording technologies, such as calcium imaging, will be used in the second phase. These data will then be analyzed and integrated to produce the brain-wide model of decision making.

Origin

IBL was founded in 2016 by Zachary Mainen (Champalimaud Center for the Unknown), Michael Hausser (University College London), and Alexandre Pouget (University of Geneva). These scientists argued in a paper published the same year [8] that, given the complexity of the questions in neuroscience and the scale of the technical challenge, it seems unlikely that the research performed by individual labs will be sufficient to understand how the brain works. Inspired by the remarkable success of large scale collaborations in physics such as CERN or LIGO, they proposed creating similar focused collaborations in neuroscience based on several core principles:

  1. A shared ambitious, yet realistic, goal (e.g. a brain-wide model of decision making in a single species),
  2. Tight coordination between theorists and experimentalists.
  3. Standardization of the behavioral tasks, hardware and data analysis to ensure reproducibility and allowing pooling of data,
  4. Open access to data and resources within and outside the collaboration, and
  5. A relatively flat hierarchy and a collaborative decision-making process.

These principles are at the heart of the IBL collaboration. [1]

Membership

Mainen, Hausser and Pouget were joined in 2016 by

David Tank and Carlos Brody (both at Princeton University) joined in 2016 but withdrew in 2017 due to conflicts of interest. Nick Steinmetz (University of Washington) joined in 2019, and Tatiana Engel (Cold Spring Harbor Laboratory) in 2020.

The Blue Brain Project is a Swiss brain research initiative that aims to create a digital reconstruction of the mouse brain. The project was founded in May 2005 by the Brain and Mind Institute of École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. Its mission is to use biologically-detailed digital reconstructions and simulations of the mammalian brain to identify the fundamental principles of brain structure and function.

Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of biochemical signaling pathways. In systems neuroscience, the ability to control the activity of a genetically defined set of neurons has been used to understand their contribution to decision making, learning, fear memory, mating, addiction, feeding, and locomotion. In a first medical application of optogenetic technology, vision was partially restored in a blind patient.

Anne K. Churchland is a neuroscientist at University of California, Los Angeles. Her laboratory studies the function of the posterior parietal cortex in cognitive processes such as decision-making and multisensory integration. One of her discoveries is that individual neurons in rodent posterior parietal cortex can multitask i.e. play a role in multiple behaviors. Another discovery is that rodents are similar to humans in their ability to perform multisensory integration, i.e. to integrate stimuli from two different modalities such as vision and hearing.
