    Sammanfattning : A major area of research in neuroscience is the effect of stimulating nerves into activation from extrinsic stimuli. This is commonly done with electric currents and external skin-contact electrodes. LÄS MER

  4. 3. Expanding multilayer perceptrons with a brain inspired activation algorithm : Experimental comparison of the performance of an activation enhanced multi layer perceptron

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Karar Wajud Abdul Aziz; Kim Emil Leonard Gripenberg; [2022]
    Nyckelord :Multi layer perceptron; neural network; biological neuron; activation algorithm; inactive active neurons;

    Sammanfattning : Machine learning is a field that is inspired by how humans and, by extension, the brain learns.The brain consists of a biological neural network that has neurons that are either active or inactive. Modern-day artificial intelligence is loosely based on how biological neural networks function. LÄS MER

  5. 4. Validation of micro-platelet LED for subcellular optogenetic activation in primary cell cultures

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Daniel Jaghobi Pourshalmani; [2018]
    Nyckelord :Optogenetics; epilepsy; microplatelet; LED; primary cell cultures; adhesion proteins; electrophysiology; Medicine and Health Sciences;

    Sammanfattning : Epilepsy is to this day still a serious neurological diseases where treatments such as pharmaceutical agents and surgery can at most alleviate the symptoms, but not cure it. This disease is still not fully understood at a cellular and network-level, but the recent advancements in the field of optogenetics can serve as an alternative way of studying the brain and diseases such as epilepsy.

    Sammanfattning : Deep Brain Stimulation (DBS) is a treatment of movement disorders such as Parkinson's disease and essential tremor. Today it has been used in more than 80.000 patients. Electrical stimulation is administered by an implanted pulse generator through an electrode surgically placed in a target brain area specific to the treated disease. LÄS MER
