#Neural Interfaces

How do neural networks actually learn? They use weights and biases that are initially randomized but are tweaked during the training process. This involves the chain rule and partial derivatives of the loss function with respect to weights and biases.

Neurons & Neural Connections Neurons are specialized cells in the nervous system responsible for transmitting electrical and chemical signals. They consist of a cell body, dendrites that receive signals, and an axon that transmits signals to other neurons or muscles. Synapses are junctions between neurons where neurotransmitters are released, facilitating the transmission of signals from one neuron to another or to a target cell.

Desde os 15 anos, vivo uma aventura no campo de pesquisas das interfaces cérebro-máquina: uma receita da ciência e da engenharia ou da neurociência e inteligência "artificial" de como fazer programas de computador ou robôs/máquinas serem controlados por pensamentos humanos. . . . Nosso cérebro funciona com eletricidade, muito menor do que aquela que tem na bateria de um celular, mas ainda capaz de produzir ondas que antenas muito sensíveis conseguem pegar em uma touca na cabeça da pessoa. . . . O legal é que pensamentos específicos como "pensar em andar" ou "pensar em estalar os dedos" produzem o mesmo tipo de sinal cerebral toda vez e ele se parece com aquelas ondas que vemos em gravador de voz! . . . Do mesmo jeito que um programa consegue aprender quando a sua voz quer dizer "Ok, Google" ou "Hey, Siri", ele também consegue aprender qual é o sinal que o cérebro da pessoa produz para um pensamento ou outro e assim conseguimos "ler a mente" das pessoas usando inteligência artificial. Essa "leitura" pode servir para acionar próteses, andadores robóticos e, no caso da pesquisa que coordeno, tentar tornar possível a identiciação e comunicação com pessoas completamente paralisadas, confundidas com pessoas em coma! . . . Quer ver onde isso vai dar? Então siga aqui para os próximos capíltulos!!! . . . #ciência #engenharia #tecnologia #neurociência #electronics #pcb #dasilvaborges #bci #neuralink #bci #braincomputerinterface #brainmachineinterface #brain #writing #inkpen

#biodigitalconvergence It is a scientific review published in the journal ACS Applied Materials & Interfaces in 2022, titled: “Optoelectronic Neural Interfaces Based on Quantum Dots” by Mertcan Han, Onuralp Karatum, and Sedat Nizamoglu Published in: ACS Appl. Mater. Interfaces, Vol. 14, pp. 20468–20490 What is it about?

Artificial brain cells, also known as artificial neurons, are synthetic constructs designed to replicate the behavior of biological neurons in the brain. These neurons aim to mimic the way biological neural networks process, store, and transmit information. Advances in this field blend neuroscience, biotechnology, and artificial intelligence to develop computational systems and biotechnological applications. Key Developments in Artificial Brain Cells: 1. Neuromorphic Computing Artificial brain cells are a key component in neuromorphic chips, which mimic the structure and functioning of the human brain. Companies like IBM (with TrueNorth) and Intel (with Loihi) have made significant advancements in this area. 2. Synthetic Biology Scientists create lab-grown neurons using stem cells or other biological processes. These neurons can interface with electronics to study brain functions or repair damaged neural tissues. 3. Organoid Development Researchers grow mini-brain organoids (3D brain-like structures) to study neurological diseases, such as Alzheimer’s or Parkinson’s. 4. AI-Driven Models Machine learning models simulate neuron-like behavior, processing data in ways inspired by biological systems. These models have revolutionized AI technologies, such as deep learning. 5. Brain-Machine Interfaces (BMIs) Artificial neurons are being integrated into BMIs to restore lost functions in patients, enabling motor control, vision, or even memory restoration. Promising Applications Medical Therapies: Artificial neurons can replace or repair damaged cells, treating conditions like epilepsy, spinal cord injuries, or neurodegenerative diseases. AI Systems: Mimicking brain-like processing for faster and more efficient computational systems. Ethical Cognitive Studies: Investigating how synthetic brain cells can help understand consciousness, learning, and decision-making.

From brain signals to robotic control 🧠🦾   Step inside Chalmers’ Neural Bionics Lab – a research environment established just 1.5 years ago to help improve life for people with neurological conditions.   Here, Assistant Professor Giacomo Valle and his team develop neurotechnologies and test different assistive devices that can interact directly with the human nervous system. Their mission is to support people who have lost movement or sensation and help restore important functions.   From brain–computer interfaces and wearable neurotech to digital models that simulate how nerves communicate, the team explores how technology can connect the brain with external devices. This could allow users to control robotic arms or even experience sensory feedback again.   The lab collaborates with international partners and Swedish clinical specialists, and works closely with participants and patients whose experiences help guide the future of neurotechnology.   🎥 Watch the full video on our Youtube channel @ChalmersUniversityofTechnology   #ChalmersUniversityofTechnology #NeuralBionicsLab #Neurotechnology #AssistiveDevices #Innovation #BrainComputerInterface #WearableTech #Engineering #Gothenburg
