Q&A

Question 1

TMS and TES in causing neural activity

Answer 1

TES officially doesn’t cause neural activity. it’s a perturbation method but it changes electricity, though not neural activity.

Question 2

Basilar membrane

Answer 2

Basilar membrane move, causing the stereo cilia to move. It’s not due to vibration of the fluid per se.

Question 3

Difference between color contrast and color constancy

Answer 3

Contrast: Waves that reach your eyes are identical but experienced differently.

Constancy; Patches with very different waves are experienced as the same.

Question 4

Cause of lateral inhibition

Answer 4

Due to connectivity in bipolar cells lateral inhibition exists. Ganglion cells have the receptive fields. It’s the bipolar cells that project onto the ganglion.

Question 5

Multivoxel pattern analysis (MVPA)

Answer 5

Getting a fine grain detail to what a certain area responds to. Like the fusiform face area. You can’t see it in fMRI as it all lights up. A certain pattern of voxels within the area can be related to a specific stimulus.

Question 6

Voxel

Answer 6

fMRI image is 3 dimentional. within this you have 1mm cubes that are stacked. These are voxels.

Question 7

Spatial patterns

Answer 7

Systematic pattern of voxel activity. Can be illustrated with specific patterns per category.

Question 8

Robust findings

Answer 8

Need to use meta analysis in order to do so

Question 9

R TPJ in involuntary system

Answer 9

It’s the circuit breaker, if focusing on something and the right TPJ is stimulated, it breaks attention and tends it toward the TPJ signal. Explains contralateral neglect
