Visual Reactive Programming – Bonsai 0121

Visual Reactive Programming – Bonsai is a Cajal NeuroKit. NeuroKits are hybrid courses that combine online lectures about fundamentals and advanced neuroscience topics, with hands-on and physical experiments.
Researchers from all over the world can participate thanks to the course material sent by post in a kit box containing all the tools needed to follow the online course. 

Course overview

Modern neuroscience relies on the combination of multiple technologies to record precise measurements of neural activity and behaviour. Commercially available software for sampling and controlling data acquisition is often too expensive, closed to modification and incompatible with this growing complexity, requiring experimenters to constantly patch together diverse pieces of software.

This course will introduce the basics of the Bonsai programming language, a high-performance, easy to use, and flexible visual environment for designing closed-loop neuroscience experiments combining physiology and behaviour data.

This language has allowed scientists with no previous programming experience to quickly develop and scale-up experimental rigs, and can be used to integrate new open-source hardware and software.

Course Teaser

What will you learn?

By the end of the course you will be able to use Bonsai to:

– create data acquisition and processing pipelines for video and visual stimulation.
– control behavioral task states and run your closed-loop experiments.
– collect data from cameras, microphones, Arduino boards, electrophysiology devices, etc.
– achieve precise synchronization of independent data streams.

The online material will be soon found here.

Extracellular Electrophysiology Acquisition 0321

To apply to the second edition of this course please visit this webpage

Extracellular Electrophysiology Acquisition is a Cajal NeuroKit. NeuroKits are hybrid courses that combine online lectures about fundamentals and advanced neuroscience topics, with hands-on and physical experiments.
Researchers from all over the world can participate thanks to the course material sent by post in a kit box containing all the tools needed to follow the online course.

Course overview

Any data we collect has been shaped by the system we used to record it. Understanding the tools involved in data acquisition gives you the confidence to make informed experimental design choices, and the freedom to combine and try new approaches while building your dream setup.

In this course, we will develop your understanding of electrophysiology data acquisition. In terms of hardware, you will learn how acquisition systems can amplify tiny signals and filter out noise. You’ll test this understanding by building your own system to measure muscle and heart signals. In software, you will encounter synchronisation considerations, as we add incoming datastreams and build an increasingly complex experimental design.

Don’t be discouraged if you secretly panic at the mention of capacitance, this course starts from the very basics. Advanced students can make the final project as challenging as they like.

Designed by Open Ephys and Open Ephys Production Site, this course will have an open-source flavour and encourage you to try new ideas, share your insights, and connect with the open-source community.

Ageing cognition

Course overview

The normal aging process is associated with reduced performance on cognitive tasks that require one to quickly process or transform information to make a decision, including measures of speed of processing, executive cognitive function, working and relational memories. Structural and functional alterations in the brain correlate with these age-related cognitive changes, such as loss of synapses, and dysfunction of neuronal networks. It is crucial to develop new approaches that consider the whole neuroanatomical, endocrine, immunological, vascular and cellular changes impacting on cognition.

This 3-week course will cover the fundamentals of cognitive aging -including inter-individual differences, cognitive and brain reserve and risk factors- and highlight the newest functional imaging methods to study human brain function. The Faculty will share the state-of-the-art molecular, optical, computational, electrophysiological, behavioral and epidemiological approaches available for studying the aging brain in diverse model systems.

Students will learn the potential and limitations of these methods, through practical experience in a combination of lectures addressing aging in both humans and animal models and hands-on-projects. They will acquire sufficient practical experience to model, design and interpret experiments and brainstorm on novel technologies and hypotheses to explore the aging of the brain using more integrative and creative approaches.

Experimental Neuroscience Bootcamp

NeuroKits are hybrid courses that combine online lectures on advanced neuroscience topics with hands-on experiments by sending a kit containing the course material wherever you are.

Course overview

This course provides a fundamental foundation in the modern techniques of experimental neuroscience. It introduces the essentials of sensors, motor control, microcontrollers, programming, data analysis, and machine learning by guiding students through the “hands on” construction of an increasingly capable robot.

In parallel, related concepts in neuroscience are introduced as nature’s solution to the challenges students encounter while designing and building their own intelligent system.

Course Partners

Voight-Kampff

What will you learn?

The techniques of experimental neuroscience advance at an incredible pace. They incorporate developments from many different fields, requiring new researchers to acquire a broad range of skills and expertise (from building electronic hardware to designing optical systems to training deep neural networks). This overwhelming task encourages students to move quickly, but often by skipping over some essential underlying knowledge.

This course was designed to fill-in these knowledge gaps.

By building a robot, you will learn both how the individual technologies work and how to combine them together into a complete system. It is this broad-but-integrated understanding of modern technology that will help students of this course design novel state-of-the-art neuroscience experiments.

Programme

The course will be held from 14:00 to 18:00 CEST

Day 1 – Sensors and Motors

What will you learn?

You will learn the basics of analog and digital electronics by building circuits for sensing the environment and controlling movement. These circuits will be used to construct the foundation of your course robot; a Braitenberg Vehicle that uses simple “algorithms” to generate surprisingly complex behaviour.

Topics and Tasks:

  • Electronics (voltage, resistors, Ohm’s law): Build a voltage divider

  • Sensing (light-dependent resistors, thermistors): Build a light/temperature sensor

  • Movement (electro-magentism, DC motors, gears): Mount and spin your motors

  • Amplifying (transistors, op-amps): Build a light-controlled motor

  • Basic Behaviour: Build a Braitenberg Vehicle

Day 2: Microcontrollers and Programming

What will you learn?

You will learn how simple digital circuits (logic gates, memory registers, etc.) can be assembled into a (programmable) computer. You will then attach a microcontroller to your course robot, connect it to sensors and motors, and begin to write programs that extend your robot’s behavioural ability.

Topics and Tasks:

  • Logic and Memory: Build a logic circuit and a flip-flop

  • Processors: Setup a microcontroller and attach inputs and outputs

  • Programming: Program a microcontroller (control flow, timers, digital IO, analog IO)

  • Intermediate behaviour: Design a state machine to control your course robot

Day 3: Computers and Programming

What will you learn?

You will learn how a modern computer’s “operating system” (Linux) coordinates the execution of internal and external tasks, and how to communicate over a network (using WiFi). You will then use Python to write a “remote-control” system for your course robot by developing your own communication protocol between your robot’s linux computer and microcontroller.

Topics and Tasks:

  • Operating Systems: Setup a Linux computer (Raspberry Pi)

  • Networking: Remotely access a computer (SSH via WiFi)

  • Programming: Program a Linux computer (Python)

  • Advanced behaviour: Build a remote control robot

Day 4: (Machine) Vision

What will you learn?

You will learn how grayscale and color images emerge and how to work with them in a Python environment. By mounting a camera on your robot, you can live-stream the images to your computer. You will then use background subtraction and thresholding to program an image-based motion detector. You will use image moments to detect and follow a moving light source, and learn about “classical” face detection.

Topics and Tasks:

  • Images: Open, modify, and save images

  • Camera: Attach and stream a camera image

  • Image processing: Determine differences in images

  • Pattern recognition: Extract features from images

Day 5: (Machine) Learning

What will you learn?

You will learn about modern deep neural networks and how they are applied in image processing. You will extend the intelligence for your robot, by adding a neural accelerator to the robot. We will deploy a deep neural network for face detection and compare it to the “classical” face detector. Ultimately, you will create and train your own deep neural network that will allow your robot to identify it’s creator, you.

Topics and Tasks:

  • Inference: Implement a neural accelerator (Google Coral USB EdgeTPU)

  • Deployment: Deploy and run a deep neural network

  • Object detection: Finding faces using a deep neural network (Single Shot Detector)

  • Object classification: Train a deep neural network to identify one’s own face (TF/Keras)

Registration

Registration fee: 450€ per person (includes shipping of the course kit, pre-recorded and live lectures before and during the course, full attendance to the course, and course certificate).

Optogenetics, chemogenetics and biosensors for cellular and circuit neuroscience

Course overview

Spatio-temporally precise manipulation and read-out of brain circuit function has been one of the longest-standing challenges in neuroscience. The recent explosion in the field of genetically encoded tools to control and measure neuronal activity has greatly facilitated investigation of brain function, ranging from single synapses to large-scale circuits. Both control and readout of neuronal activity can now be achieved over orders of magnitude in space and time, ranging from micrometers to entire brain regions and from milliseconds to days.

This course will provide participants with the opportunity to gain hands-on experience using the latest genetically encoded tools and state-of-the-art equipment for brain circuit investigation. A particular focus will lie on multiplexed manipulations and read-out of brain circuits. Participants will be familiarized with the biophysical principles behind the sensors and actuators, and given training complementary to their background in the technical aspects of experimental approaches.

Hands-on experiments will employ optogenetic and chemogenetic actuators, including excitatory and inhibitory ion channels, pumps, enzymes and G-protein coupled receptors. These actuators will be complemented by genetically encoded indicators of neural activity, including calcium and voltage indicators as well as indicators for neurotransmitters and neuromodulators such as glutamate, dopamine and norepinephrine.

The course will cover a wide range of experimental systems with an emphasis on functional brain circuits in vivo. Finally, participants will be guided through data analysis and conceptual interpretations of their experiments.

In addition, the Cajal Programme will not, as far as possible, request the registration fee from selected applicants until the course has been secured and confirmed. Nevertheless, should the course be cancelled before the course dates and the registration fees already collected, participants will be reimbursed.

Extracellular Electrophysiology Acquisition 1221

This is a Cajal NeuroKit course that combines online lectures about fundamentals and advanced neuroscience topics with hands-on and physical experiments.

Researchers from everywhere can participate because the course material is sent home in a kit box.

This course is now at its second edition.

Course overview

Any data we collect has been shaped by the system we used to record it. Understanding the tools involved in data acquisition gives you the confidence to make informed experimental design choices, and the freedom to combine and try new approaches while building your dream setup.

In this course, we will develop your understanding of electrophysiology data acquisition. In terms of hardware, you will learn how acquisition systems can amplify tiny signals and filter out noise. You’ll test this understanding by building your own system to measure muscle and heart signals. In software, you will encounter synchronisation considerations, as we add incoming datastreams and build an increasingly complex experimental design.

Don’t be discouraged if you secretly panic at the mention of capacitance, this course starts from the very basics. Advanced students can make the final project as challenging as they like.

Designed by Open Ephys and Open Ephys Production Site, this course will have an open-source flavour and encourage you to try new ideas, share your insights, and connect with the open-source community.
