NeuroAI – Neuroscience and AI

Course overview

Modern deep learning methods provide some of the best tools to model behavior and brain function today. Excitingly, AI systems have become the first artificial models capable of matching human performance in sophisticated cognitive tasks, such as visual recognition, language processing, and strategic planning. This unique capability makes them a key test bed for neuroscience research: by studying how these AI systems solve complex problems, we can generate and test hypotheses about the computational principles that biological brains might use. Moreover, thanks to amazing progress in neuroscientific experimental recording techniques over the last decade, we now have access to vast amounts of complex data, which can be used in computational modeling, across multiple modalities – from neural activity of thousands of neurons, to anatomical details of neuronal circuits, to whole brain neural recordings during complex behavior of humans and animals. These exciting developments—in both AI methodology and neuroscientific recordings—have inspired an emerging area of research at the intersection of neuroscience and AI.

The course gives a hands-on introduction to modern AI methods, including deep learning, and how it can be used for analyzing and modeling brain activity and behavior. Experts in the field will teach the basics of AI, and how to use them as models of the brain, cognition, and behavior.

Students will design projects applying machine learning methods to neural recording and behavioral data sets.

Datasets

We encourage course faculty to bring datasets that can be used for projects. Here are some examples of datasets that will be available for project work

  • Calcium imaging data from mouse primary visual cortex in response to natural images and videos from the SENSORIUM competitions 2022 and 2023
  • Large dataset of human choices on a 4-armed drifting bandit task.
  • Data from foveal V1 of free-viewing marmosets along with continuously monitored gaze. Data from Marmoset retina with the same eye traces.
  • Publicly available data from the Brain-Score benchmark (vision and language). The vision data include non-human and human primate electrophysiology and fMRI recordings spanning the visual ventral stream and associated object recognition behaviors. The language data are human neuroimaging and reading time measurements. Meta-data from thousands of model alignment scores on all of the Brain-Score benchmarks.
  • A dataset with over 29,000 neurons responding to up to 65,000 natural image presentations in mouse V1. The neurons were expressing jGCaMP8s and we recorded their activity using two-photon calcium imaging at a rate of 30Hz.
  • Neuropixels speech dataset comprising spiking activity from >500 single neurons in awake human participants undergoing brain surgery. Neurons were recorded while participants listened to simple English sentences. Associated metadata for each neuron such as its anatomical position along the superior temporal gyrus and cortical depth will also be provided.

Techniques

Through hands on tutorials and project work, students will have the opportunities to learn about computational approaches in NeuroAI such as:

  • Deep learning models for vision and language (CNNs, transformers)
  • Reinforcement learning algorithms
  • State space models for neuronal time series
  • Machine learning for biophysical models of neuronal circuits

Completed in 2010, the Champalimaud Centre for the Unknown is a state-of-the-art centre that houses the Champalimaud Clinical Centre and the Champalimaud Research, with its three parallel programs – the Champalimaud Neuroscience Programme, the Physiology and Cancer Programme, and the Experimental Clinical Research Programme.
Initially focused on a system and circuit approach to brain function and behavior, the Centre expanded to incorporate molecular and cell biological expertise. The Centre comprises 26 research groups (circa 400 researchers) leading independent curiosity-based research.

Facilities
The Centre provides Facilities dedicated for Training, some in their entirety, for use by the CAJAL Advanced Neuroscience Training Programme. These include the Teaching Laboratory, a fully equipped open lab space for 20-30 students that can be dynamically reconfigured to support a full range of neuroscience courses. It also overlooks, via floor to ceiling windows, a tropical garden and the river. The experimental spaces include: Imaging Lab: A dark-room containing a full size optical table is used for advanced imaging setups (two-photon microscopy, SPIM, etc.) and custom (course-designed) optical systems.

Machine learning for neuroscience

Course overview

Neuroscience has played an important role in the history of Artificial intelligence and Machine learning. Artificial neural networks are inspired by neuronal physiology and are today the core of Deep Learning. This common history continues today. Machine Learning methods are developed into tools that allow for a higher quality of data processing in the study of animal behavior and brain activity. Machine Learning is also used to model the brain as it can solve similar problems to what brains solve and the basic units of processing may be comparable.

The course gives a hands-on introduction to Artificial Intelligence and Machine Learning and how it can be used for data acquisition, analysis and modeling brain activity and behavior. Experts in the field will teach the basics of Machine Learning and how to apply it to Neuroscience and will also discuss the limits of the field, and what are the boundaries of application and how Neuroscience and Psychology could inform new systems.

Students will design projects applying machine learning (ML) methods to neural recording and animal behavior data sets. Neural recording data sets provided will be from a variety of techniques, including electrophysiology, calcium imaging, and fMRI. Behavior data sets provided will be from video. Students may focus on developing new ML algorithms for improving automated tracking, segmentation, categorization, or representation learning. Alternatively, they may focus on applying these ML methods to large data sets to discover new biological insights. A third option is to explore ML-based computational models of neural activity or behavior. Through these projects, students will gain hands-on experience using modern ML approaches, coding in PyTorch, and gain a deeper understanding of the power and potential failures of ML.
