Personal Website

About

I created the website you are currently browsing from scratch, using Hugo, a static site generator written in Go. The website is hosted on Github pages, and the source is available at https://github.com/m0ose01/m0ose01.github.io.

Event Related Potentials during the Boston Naming Task, and their Changes in ALS (Conference Poster)

About

This poster was presented at the 2024 BrainBox Initiative conference in London. It is based on work from my bachelor’s thesis on language impairment in amyotrophic lateral sclerosis.

You can view the poster on the BBI 2024 or McMackin lab websites.

Abstract

Background

  • ALS: a chronic, terminal neurodegenerative disease, causing progressive paralysis and death within 3-5 years.
  • Language impairment is common in ALS, and is associated with worse outcomes, e.g., shorter survival.
  • The Boston Naming Test (BNT) is an picture naming test on which many people with ALS show impairments.
  • Biomarkers for improved diagnosis, prognosis, and disease monitoring are needed for improved treatment/clinical trials
  • We used electroencephalography (EEG) to record neural activity during a language task.
  • Advantages over other measures (e.g., fMRI)
    • Directly measures neural activity
    • Low cost
    • High temporal resolution

Aims

  • To investigate whether event related potentials (ERPs) can be detected during the BNT.
  • To see whether people with ALS display abnormalities in these ERPs, and whether this relates to language function

Tic Tac Terminal

About

For my CS50x final project, I created a TUI-based Tic-Tac-Toe game, with ncurses, written in C. The user can create a board of arbitrary size, so long as there is space on the screen.

Installation

See the github page for more information on how to install tic-tac-terminal. See also the rust rewrite.

CFS/pythonCFS

About

The Cambridge Electronic Design File System (CFS) is the file format used by the Signal Software Suite to record electrophysiological data, such as data from Transcranial Magnetic Stimulation experiments.

CED distributes a C library to read and write these files. However, this library only compiles on Windows. This library is an attempt to reimplement part of CED’s CFS library using only platform-agnostic code compliant with the C standard. Some outdated features will be dropped, such as support for MS-DOS, or near/far pointers for 16-bit segmented memory architectures
