Program

First day | 8^th April: Lectures covering different topics in neuroengineering.

Second day, optional | 9^th April: Hands-on practical sessions on basic lab techniques in neuroengineering.

The hands-on practical sessions are targeted for students (MSc and PhD), but are in fact open to everyone. Every practical session has a duration of 3h and each participant can only choose (register) one hands-on practical session. The list of available practical sessions is presented below.

Please notice that the number of available seats in some sessions are very low. The minimum number of participants per session is 2.

Hands-on Practical Sessions

S1 – Basics of Neuronal Cell Cultures

[Responsible: Cátia Lopes, NCN - INEB/i3S]

Cell culturing techniques are widely used in neuroengineering studies and have significantly improved our understanding of the physiological and pathological processes of living organisms. This workshop session is intended to provide an introductory training in the basic requirements for successful cell culturing. With this hands-on training session, the participants will get acquainted with a number of valuable resources and guidelines required to establish and maintain a cell culture, as well as the basic principles of sterile technique and laboratory safety issues.

S2 – Memristive artificial synapses: from device principles to neuromorphic applications

[Responsible: Catarina Dias, IFIMUP]

Neuromorphic devices use the brain's structure and operation principles as a promising solution for modern computational storage and processing demands. Memristors, a new class of electronic devices, resemble properties similar to neural synapses. They behave like resistors whose resistance depends on the current that passed through the device. This session will start with an introduction to the memristor and then followed by the electrical characterization of some real examples. Finally, the results will be analyzed to characterize and distinguish different devices.

~~S3 – Principles of patch-clamp electrophysiology~~ (FULL)

[Responsible: Liliana Luz, IBMC/i3S]

Electrophysiology is the biomedical field dealing with the study of the electrical properties of cells and tissues. The patch-clamp technique is a major tool in electrophysiology which allow us to study cell excitability, functions and pharmacology of ion channels. Understanding how neurons respond to electrical stimuli is an essential element in the design of systems capable of modulating the activity in neuronal populations. In this practical session participants will learn the very basics of patch-clamp electrophysiology and will have to possibility to record the activity of neurons subject to electrical stimulation.

S4 – Introduction to the NEURON modeling software – in silico neuroscience and detailed simulations of neurons in a computer

[Responsible: Paulo Aguiar, NCN - INEB/i3S]

Neurons are cells specialized in transmission, storage and processing of information. Understanding the complexities of neuronal dynamics in normal conditions, in order to devise correction strategies in pathological conditions, requires detailed modeling and computer simulations. This hands-on practical session gives an introduction to the NEURON simulation environment, a well-established tool for in silico neuroscience and the workhorse software of the Human Brain Project. Participants will learn how to perform biophysically detailed simulations of single neurons and small neuronal circuits. Participants are requested to bring their laptop for the session.

~~S5 – Principles of multielectrode arrays (MEAs) electrophysiology~~ (FULL)

[Responsible: José Mateus, NCN - INEB/i3S]

Multielectrode array (MEA) technology is at the forefront of recording electrical activity from large neuronal ensembles. MEAs enable electrophysiological recordings of hundreds of neurons simultaneously, thus are of great use in both basic and clinical/applied neuroscience. Furthermore, different microelectrodes can be used to both record and stimulate neuronal activity in the same experiment. In this practical session, the participants will get acquainted with the principles of MEA experiments and have the possibility to evoke and record extracellular signals from in vitro neuronal networks.

~~S6 – Imaging neuronal activity with Calcium dyes~~ (FULL)

[Responsible: Miguel Aroso, NCN - i3S/INEB]

During electric activity of neurons, the cytoplasmatic calcium concentration rises transiently to values that can be 100x higher than in resting state. Calcium dyes are used to monitor neuronal activity by accessing these intracellular changes of Ca2+ concentration. The calcium dyes are typically organised by two parts: a chelator that binds to free Ca2+ and a fluorophore that emits fluorescent light and when it bind to Ca2+ the emitted fluorescence increases. Fluorescence is commonly recorded by an optical imaging system (microscope) with a high-speed camera, however, advanced imaging processing methods are required to extract precise neuronal activity measurements. In this session, participants will have the opportunity to record neuronal cell cultures labelled with a commercial calcium dye and analyse the acquired data with a software developed in-house.

S7 – Introduction to basic concepts of neuronal morphometric analysis in imageJ

[Responsible: Ana Gerós, NCN - INEB/i3S]

In neurons, shape and function are intimately related. Quantification of morphological characteristics (morphometrics) is therefore an important step in the evaluation of many experimental conditions. This practical session gives an introductory crash course on neuronal morphometric analysis for people with little or no knowledge in the subject. The following case studies with 2D fluorescence images, and associated image analysis workflows, will be addressed: a) neurite tracing and total fiber length; b) detecting and counting spines; c) automatic cell body segmentation and area calculation; d) Sholl analysis; in addition to a few others. Participants should have already some experience with imageJ/Fiji.
