Pangolin Scales project with Anouk Wipprecht 🥰🥰! Anouk has crafted a dress with 64 integrated actuators (32 movable scales, 32 LEDs), and g.tec has connected it to our 1024-channel BCI system, realized with g.Pangolin 🥰🥰🥰. The g.Pangolin electrodes comprise grids with 16 channels each. By situating 64 channels on the human scalp, we can record from 1024 EEG channels. Initially, EEG data from Megi was recorded to calibrate the BCI system, and then, through the dress's API, the actuators were controlled in real-time. 👉To learn more about the Pangolin Dress: https://lnkd.in/d2H2g-uc 👉To read more about the BCI system: https://lnkd.in/dP_Y4iGm 👉To learn more about g.tec: https://lnkd.in/gnZryzQQ 👉To get an offer for the setup: https://lnkd.in/dPuTcsWA #BCI #EEG #gtecmedical #neurotechnology #neuroscience #braincomputerinterface

📚 An Overview of Neurons 🧠 Neurons are the fundamental units of the nervous system, responsible for transmitting information throughout the body. Here is an overview of their key structures and functions ⤵️ 🧠 Cell Body (Soma): The soma contains the nucleus and organelles like the rough ER and ribosomes, which are vital for protein synthesis and energy production. It regulates the neuron’s function and keeps it alive. 🌿 Dendrites: Dendrites are the branched extensions that receive electrical signals from other neurons. They transmit these signals to the soma for processing. 📡 Axon: The axon sends signals away from the soma to other neurons or muscles. Its myelin sheath and nodes of Ranvier help speed up signal transmission. 🔗 Synapse: Neurons communicate at synapses, where neurotransmitters cross the synaptic cleft. These chemicals bind to receptors on other neurons, enabling signal transmission. 🛠️ Microtubules and Neurofibrils: These structures provide the neuron with internal support. They also help transport materials throughout the neuron. #Neuroscience #Science #Biology #Education

Day 2️⃣ at #FENS2024 Did you know that 🐭 are skilled climbers? 📌 The importance of vertical activity in rodents is often an underestimated aspect in motor function and #behavior, and hence the analysis of XY position only is a limitation in many current studies. To overcome this limitation, Ugo Basile has engineered the unique and innovative Climbing Test. The device, developed in collaboration with the laboratory of Prof. Sidney Negus from Virginia Commonwealth University, provides valuable insights into #physiology, behavior, and responses to environmental and #genetic factors, making it an essential component of biological and #biomedical studies involving these rodents. ➡️ Learn more about Climbing Test by Ugo Basile: https://lnkd.in/dbw2Z3s7 📍Join us at Federation of European Neuroscience Societies - FENS Forum 2024 to learn more about our revolutionary Climbing Test. Visit us at booth 201 to discover more about our innovative solutions! #Neuroscience #ResearchInnovation #ClimbingTest #MotorFunction #ScientificExcellence

🚀 Thrilled to Share! 🚀 We're proud to announce our latest review paper, "Basic Models to Advanced Systems: Harnessing the Power of Organoids-Based Microphysiological Models of the Human Brain," is now published in #Biofabrication, IOP Publishing ! Understanding the complexities of the human brain in health and disease remains a significant challenge in neuroscience. Traditional animal models fall short in accurately mirroring human biology, necessitating the development of more predictive models. Our review explores the evolution of advanced in vitro systems like organoids, assembloids, and microphysiological systems (MPSs), which bridge the gap by offering more accurate representations of human brain biology. Special thanks to all the authors: Katherine Boylin, Grace Aquino, Michael Purdon, Kimia Abedi, and Magdalena Kasendra. This milestone is particularly significant for Katherine Boylin, who recently graduated in BME - University of Cincinnati while performing her Co-OP research project at Cincinnati Children's, as this is her first peer-reviewed publication. Congratulations, Katherine! 🎉 📖 Read it here: https://lnkd.in/eRGdsGYs #Neuroscience #Organoids #MicrophysiologicalSystems #Biofabrication #ScientificResearch #OrganOnChip

Project 19: Controlling servo claw using eye blinks Basic Concept: Detecting the EOG signals (biopotential signals from eye movements) using BioAmp EXG Pill and taking it as a trigger to control the servo claw What is Electrooculography (EOG)? Electrooculography (EOG) is a technique for measuring the corneo-retinal standing potential that exists between the front and the back of the human eye.The resulting signal is called the electrooculogram. Where can we use this concept in real world scenario? Please mention your ideas in the comments. About the series of projects: We started a series of posts where we will be sharing step by step guide on how to make various HCI and BCI projects using our BioAmp Hardware. So anyone who is a beginner and wants to explore neuroscience can follow along and learn how the biophysiological signals (EEG, EOG, EMG, ECG) are being produced in body and how can we use them in making some real world applications.

A recent study by Wang et al. has unveiled new insights into how the biological clock, located in the #suprachiasmatic nucleus (SCN), encodes the time of the day. This was achieved through interdisciplinary research applying machine learning methods to large-scale calcium imaging data of SCN neurons. The study reveals that population-level #calcium signals predict hourly time and that there are distinct functional subtypes of neurons, visible as modular ripple-like patterns, in the SCN space. All SCN #neurons contribute uniformly in time computation, and each module has a unique representation of time features. These findings provide a deeper understanding of the mechanisms underlying the function of the mammalian central circadian pacemaker and shed light on the organization of time representation in the SCN.
