Neuro Synthesia quiz

Meissner's corpuscles

smaller multiple mechanoreceptors around the hand that allow you to feel the different textures of an object on one finger vs the other

Pacinian corpuscles

larger mechanoreceptors around the hand that are just a big area that doesn't allow you to distinguish much between difference in texture/feeling

Mechanoreceptors

receptors on the body that take stimuli and convert them into readable electrical signals

Two-Point discrimination

distance to where you can tell that something is two points touching you versus your brain thinking only one thing is touching you since the two points are so close to eachother

Thermoreceptors

neurons sensitive to temperature that adapt overtime and have less frequent action potentials as they adapt

Synesthesia

the 5 senses get mixed up instead of remaining separate

Cross wiring/activation

happens in the brain were neighboring brain regions don't inhibit another region's activity like they normally do, this chemical imbalance of the stuff that reduces the inhibition would cause activity in one area to elicit activity in another

Most common case of synesthesia

associating numbers with colors by actually seeing the colors

Agnosia

inability to recognize objects even though general sensory systems are normal

Neglect syndrome

part of body or part of world is neglected and its very existence is denied
