  1. 1. Optimisation of parallel k-d trees using heuristics for neuron touch detection task

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Daniel Benedí García; [2022]
    Keywords : ;

    Abstract : Neuroscience has benefited from neuronal network simulation and an important task in the simulation is finding points in space where two neurites approach each other so a synapse could be formed. The task of finding the touching points could be seen as similar to the ray collision in ray tracing in computer graphics. READ MORE

  3. 2. Micromagnetic Study of Current Induced Domain Wall Motion for Spintronic Synapses

    University essay from Uppsala universitet/Energimaterialens fysik

    Author : Dimitrios-Petros Petropoulos; [2021]
    Keywords : computational physics; micromagnetism; micromagnetic simulations; Mumax3; current induced domain wall motion; domain wall driving; spin current; spin transfer torque; synapse; memristor; Neuromorphic computing; spintronic; brain inspired computing; Permalloy; nanowire; nanostrip; notches;

    Abstract : Neuromorphic computing applications could be made faster and more power efficient by emulating the function of a biological synapse. Non-conventional spintronic devices have been proposed that demonstrate synaptic behavior through domain wall (DW) driving. READ MORE

  4. 3. Analyzing the scalability of R*-tree regarding the neuron touch detection task

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Brask; Filip Berendt; [2020]
    Keywords : ;

    Abstract : A common task within research of neuronal morphology is neuron touch detection, that is finding the points in space where two neurites approach each other to form a synapse. In order to make efficient use of cache memory, it is important to store points that are close in space close in memory. READ MORE

  5. 4. Simulating Facilitation in a Spiking Neural Network

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Alexander Kuzmin; [2020]
    Keywords : Biology and Life Sciences;

    Abstract : Many insects are able to detect, isolate and track small targets that move quickly against a dynamic background. This ability is enabled by a group of neurons called small target motion detectors (STMD). These neurons, among other properties, have a type of short term memory called response facilitation.

  6. 5. Monte Carlo Optimization of Neuromorphic Cricket Auditory Feature Detection Circuits in the Dynap-SE Processor

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Mattias Nilsson; [2018]
    Keywords : Neuromorphic engineering; Spiking neural networks; Pattern recognition; Feature detection; Training protocol; Software tools;

    Abstract : Neuromorphic information processing systems mimic the dynamics of neurons and synapses, and the architecture of biological nervous systems. By using a combination of sub-threshold analog circuits, and fast programmable digital circuits, spiking neural networks with co-localized memory and computation can be implemented, enabling more energy-efficient information processing than conventional von Neumann digital computers.
