  1. 1. Attending to the now : A systematic review of the neural correlates of trait mindfulness

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Ellen Vesterlund; [2021]
    Keywords : Trait mindfulness; fMRI; MRI; wellbeing;

    Abstract : Trait mindfulness refers to the tendency of being mindful in everyday life. Individuals characterized with high trait mindfulness have reported high subjective wellbeing and are less prone to depression and stress. The aim with this systematic review was to investigate the neural correlates of trait mindfulness. READ MORE

  2. 2. Psychedelic oscillations : A systematic review of the electrophysiological correlates of classic psychedelics

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Shabo Annerud Awrohum; [2021]
    Keywords : Electrophysiological; psychedelic; signal diversity; spectral analysis; functional connectivity;

    Abstract : Background: Recently there has been a revitalization in research on classic psychedelic substances. This class of drugs has been found to produce intense and profoundly meaningful experiences, and offers a unique opportunity to study the neural correlates of the sense of self. READ MORE

  3. 3. Measurement of timescales of cortical neuronal activity in behaving mice

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

    Author : Sasa Lekic; [2021]
    Keywords : Neural activity; prefrontal cortex; visual cortex; Timescale; Spike trains; Functional hierarchy; Neural aktivitet; PFC; Timescale; Spike train; Funktionell hierarki;

    Abstract : Electrical activity is omnipresent throughout the brain, and it varies dependant on the brain region. Areal hierarchy has been suggested to be one of the main principles of the organization of the brain, but there is not a lot of evidence available related to the specialization of the brain’s regions in the temporal domain, that is, how the activity evolves over time.

  4. 4. Estimating the relative phase-difference in EEG using the matched phase reassigned cross-spectrogram

    University essay from Lunds universitet/Matematisk statistik

    Author : Maria Åkesson; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : In brain connectivity research the relative phase between two EEG oscillations is particularly relevant, as it could provide information about the conduction delay between two regions. However, due to EEG signals containing large amounts of noise and spurious connections, the relative phase is seldom estimated. READ MORE

  5. 5. Functional connectivity analysis in the human brain using ultra-high field MRI

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Theodor Rumetshofer; [2021]
    Keywords : Biology and Life Sciences;

    Abstract : Introduction: Functional magnetic resonance imaging (MRI) is a non-invasive method which uses a combination of a strong magnetic field and radio frequency pulses to image magnetic difference between oxygenated and deoxygenated blood in the human brain. This contrast differences can be used to identify areas in the brain when subjects performing an active task in the MRI scanner. READ MORE
