Noninvasive Brian stimulation
9 important questions on Noninvasive Brian stimulation
What can you do t=with corticospinal excitability ?
- Can apply one pulse to the brain
- create motor evoked potential
- increase muscle response (stimulate right spot)
What info does the measure of the motor evoked potential give you?
- the higher the motor cortex excitability is, the less stimulation you need
What did the study by Muller-Leinsz et al. 2018 say/do?
- Let people play game with farm or unfair players
- first ultimatum game then dictator game
- inhibiting of right cortex led to fairer behaving rate in the 2nd game
- direct effect of TMS is to the cortex
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How does tDCS work?
- Use a weak current (A) that will leak into the brain cause it is constantly on
- very small amount of electrical signal --> small number of neurons will respond to this leak
- has very big field not very precies
What is Anode stimulation?
- Affects the resting state potential
- likelihood of neuron to fier/increase
What anodes en cathodes do in tACS?
- Will create a current in a wavy and alternating way
- similar to neuronal patterns
What can oscillatory potentials create?
- Neural synchronization
- neurons will start to move the same way as in the current
When can you use TMS in the clinic?
How do they use TMS in depression?
- Place coil over right prefrontal part of the brain with 20Hz in order to excite neurons in this area
- might help depressed people to be less sensitive to punishment and motivate approach behavior
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
