Applications of Neuroscience Flashcards
What is a BCI?
Brain Computer Interface
What is the neurodegenerative disease that is typically linked with BCI use?
Amyotrophic Lateral Sclerosis (ALS)
What type of EEG brain response does Birbaumer et al. (1999) utilise in their spelling BCI?
Slow Corticol Potentials
What type of learning potentially leads to effective control of Birbaumer et al.’s (1999) spelling BCI?
Operant/Instrumental Learning
Name at least two other EEG brain responses which have been used (or investigated for potential use) in BCI devices
Sensorimotor rhythm and P300
Name two invasive approaches that been used (or investigated for potential use) to collect brain activity for BCI use?
Action potentials and electrocorticograms
Name two advantages of non-invasive BCI approaches over invasive BCI approaches?
No surgery and cheaper
Name two advantages of invasive BCI approaches over non-invasive BCI approaches?
Fast learning and application, difficult to knock out of place.
What is machine learning?
Imposes the main load of the learning task to the learning machine
What is the main advantage of machine learning relative to the type of learning associated with Birbaumer et al.’s (1999) spelling BCI?
Faster training and collobration period, less effortful for the user.
How successful have BCI devices been for facilitating communication in those who are CLIS?
Low success.
Describe the additional fMRI study by Perth et al (2015) for detecting deception.
Guilty intention group
Guilty action group
informed innocent group
ppts answered a series of questions in the fMRI which were neutral, to do with the planning phase of the crime or the execution phase of the crime.
The classifier ‘support vector machine’ was sensitive to detecting crime related memories vs neutral memories.
