Module 1 Flashcards
what are the three sub-disciplines of motor behviour?
motor control, motor learning/acquisition, motor development
define motor behaviour
consequence of constraints
what are advantages of using EEG?
good temporal resolution - can see immediate changes
what are disadvantages of using EEG?
only captures activity at cortical surface so its spatially limited, we can’t
see specific brain regions
what does MRI measure?
BOLD signal (Blood Oxygen Level Dependent) during
“activity”
what are the advantages of using MRI?
high spatial resolution
(deep resolution in the brain)
what are the disadvantages of using MRI?
poor temporal resolution - can’t see immediate changes, expensive as hell
what does transcranial magnetic stimulation do? (TMS)
generates a pulsed magnetic field to de/hyperpolarize specific regions of neurons in the brain, creating temporary lesions
what does transcranial Direct Current Stimulation (tDCS) do?
Generates low-level
electrical current, excite/inhibit areas of the brain before an activity
how do brain probing tools help us?
they allow us to see if certain parts of the brain are involved in certain activities
what are two examples of brain probing devices?
TMS and tDCS
what are the three main constraints on motor behaviour?
personal/individual, task, environment
what are three reasons we study motor behaviour?
- helps us to teach efficiently to promote skilled performance (sport, clinical, military)
- Aid in (re)learning human movements (physio.,
occupational therapy, rehabilitation) - facilitate understanding of why & how they act to prevent errors (human factors/work place safety
